The impact of liquid cooling systems and technologies on new energy vehicles

Under the strategic deployment of carbon neutrality, the domestic and public use of new energy vehicles has become more and more in-depth and extensive. When talking about the liquid cooling system of new energy vehicles, we have to think of its important role in electric vehicles. As an advanced and era-leading high-tech temperature control method, liquid cooling technology is mainly used to regulate the temperature of batteries, motors, and electronic control systems to ensure that new energy trams can operate efficiently and safely. The impact of liquid cooling technology on fast charging First, let us first understand the advantages of liquid cooling technology in terms of fast charging. During the fast charging process, the battery will generate a lot of heat due to the high current. If heat is not dissipated in time, excessive battery temperature will affect performance and safety. The liquid cooling system can quickly transfer the heat generated by the battery to the coolant and quickly discharge it through the cooling system, ensuring that the battery temperature is always maintained within a safe and ideal range. This not only greatly improves the efficiency of fast charging, but also significantly enhances the safety of the charging process. The impact of liquid cooling system on the life of new energy batteries Liquid cooling technology plays a key role in the life of new energy batteries. The operating temperature of a battery is one of the key factors affecting its lifespan. Too high or too low temperature will accelerate battery a

How does liquid-cooling tube help thermal management of electronic equipment?

Liquid-cooling tube, also known as cooling serpentine tube, is a heat exchange component commonly used in cylindrical batteries. The liquid-cooling tube uses a unique hollow structure pipe and is developed with high precision manufacturing quality. It has a large inner surface area can achieve more efficient heat conduction, so it is often used in battery packs with cylindrical cells. As we all know, high temperature is the invisible killer of electronic components, integrated circuits, etc. High temperature will not only shorten the service life of the equipment, cause unstable system operation, and even cause problems such as component burnout. Therefore, heat dissipation treatment of electronic components and integrated circuits cannot be ignored. There are many types of heat dissipation methods, such as liquid cooling, air cooling, and evaporator air cooling. Among these heat dissipation methods, liquid cooling stands out for its excellent heat dissipation efficiency, low space occupation and silent characteristics, and has been widely used. Liquid cooling devices usually use pumps to circulate the coolant in the liquid cooling tube and dissipate heat. Therefore, the liquid-cooling tube is an important part of the liquid cooling device. It can not only serve as a channel for the coolant to flow without contacting the heating element, but it can also serve as a heat transfer pipe, directly in contact with the heating element, absorbing the heat of the heating element and transferring the heat to the coolant.

BYD's billion India plant: on or not?

Recently, it has been reported that Chinese electric vehicle manufacturer BYD's plan to build a factory in India has been canceled. This news has garnered widespread attention and speculation in the industry. It is understood that BYD originally planned to invest around $2 billion in India to establish a large-scale electric vehicle manufacturing plant to meet the country's demand for electric vehicles. However, due to a series of reasons, BYD has decided to cancel this plan. Firstly, the Indian government's policies are not supportive enough of the development of the electric vehicle industry. Despite the Indian government's promotion of electric vehicles, the support in terms of infrastructure and subsidy policies is not strong enough, which has raised doubts about the investment prospects of building a factory in India for BYD. Secondly, the demand for electric vehicles in the Indian market is not strong. Despite being the second most populous country in the world, the sales of electric vehicles in India have been low. According to statistics, electric vehicle sales in India only account for 1% of the overall automobile sales, which has raised concerns about the return on investment for BYD in building a factory in India. In addition, competition from domestic electric vehicle manufacturers in India is also one of the reasons for BYD's cancellation of the plan. Indian domestic companies such as Tata Motors and Mahindra & Mahindra have achieved certain achievements in the field of electric vehicles. Compared to international brands, domestic companies have certain advantages in terms of brand recognition and sales network, which has put BYD in fierce competition in the Indian market.

High-power IGBT Heat Dissipation Looks Towards Liquid Cooling

High-power IGBT heat dissipation looks towards liquid cooling The insulated gate bipolar transistor (IGBT) is a key component in new energy conversion systems and high-voltage power switching devices, and is a representative platform device in high-power semiconductors. As a core functional device of a power electronic control circuit with high heat flow density, most of the failures of IGBT modules are related to thermal faults. The accumulation of heat can seriously affect the working condition and performance of the device, and if the temperature is too high (150°C), it can also pose a serious threat to the normal operation of the whole system module, or even damage it. Therefore, it is important to do effective thermal detection and management of IGBTs. Trumony has professional technical and design engineers who are able to design efficient, stable, compact and lightweight liquid-cooled heat transfer solutions for different IGBT projects. There are currently two types of IGBT heat dissipation: passive heat dissipation (heat dissipation by natural convection, which dissipates heat into the atmosphere without external forces) and active heat dissipation (such as air or water cooling). Passive heat dissipation includes Fin cooling: the heat generated by the IGBT will be dissipated by natural convection through the fins of the heat sink; Heat pipe cooling technology: heat pipes as two-phase heat transfer devices, with low heat transfer temperature difference, high heat transfer performance, high effective thermal conductivity advantages, simple working principle, no mechanical maintenance, purely simple and easy to operate passive method. (If fins are embedded, the efficiency of the heat dissipation will be increased even more) Phase Change Material (PCM) based heat dissipation:

Structural design of aluminium alloy battery pack casing

After the rapid development in recent years, China has now become the world's number one country in terms of production and sales of new energy vehicles. With the introduction of the national subsidy policy for new energy vehicles in 2019 and the increase in range requirements, higher requirements for the energy density of the battery system have been put forward. There are two paths to improve the energy density of the battery: one is to increase the specific energy of the single cell; the other is to lighten the structure of the battery pack. To increase the specific energy of a single cell is technically difficult, with long R&D cycles and large capital investment, while making the structure of the battery pack lighter is easier to achieve. The use of aluminium alloys in automobiles has been commonplace for a long time. Aluminium has many advantages such as low density, high specific strength, thermal stability, corrosion resistance and good thermal conductivity, non-magnetic, easy to shape and high recycling value, making it an ideal material for lightweight battery pack design. At present, the mainstream scheme for battery pack shell materials is extruded aluminium alloy shell + PP/glass fibre composite top cover. From the point of view of current developments, the aluminium alloy shell and plastic top cover solution has the prospect of lightweighting. The aluminium extrusion profile + stir friction welding + MIG welding solution is used for the housing, which has a low overall application cost, meets the performance requirements and enables the integration of the circulating waterway for water-cooled batteries. The top cover uses a non-metallic top cover, mainly using PP/glass fibre + LFT-D moulding process, which can improve the efficiency of production and also meet the requirements of flame burning and sealing perfor

A milestone breakthrough! --Condensed Battery

A milestone breakthrough! --Condensed Battery The introduction of CATL's 'Condensed Battery' will greatly promote the further development of battery technology and is expected to be widely used in new energy vehicles, energy storage, aviation and other fields in the future, further enhancing China's position and competitiveness in the global new energy industry, which is a major innovation that has been in the making for a long time, but also a It is a milestone breakthrough that is future-proof and fully meets the all-round requirements of electrification. With the gradual maturation of lithium-ion battery technology, its energy density is approaching its theoretical limit. This means that the traditional battery upgrade route faces many technical and manufacturing challenges. To meet full electrification and carbon neutrality targets, the industry urgently needs more advanced electrochemical material systems to achieve breakthroughs in higher energy densities. Of course, higher energy densities also mean greater risks and challenges, such as higher demands on battery safety. Therefore, the search for more advanced electrochemical material systems is the core crux of battery technology to achieve new breakthroughs. This new condensed battery is an innovation using solid-state battery technology, the core technology of which is the design and manufacture of condensed electrolytes. Traditional lithium-ion batteries use liquid electrolytes, which are flawed by the need to withstand extreme operating conditions such as high temperature and pressure and violent impacts within a short period of time, easily causing safety problems such as leakage and combustion. The condensed electrolyte, on the other hand, is a new type of electrolyte developed by CATL - high power bionic condensed electrolyte, which is a combination of various functional materials, with a combin

Five ways to keep power batteries out of thermal runaway!

Five ways to keep power batteries out of thermal runaway! Thermal runaway means that the battery generates a large amount of heat during operation and the temperature rises rapidly beyond the safety range, thus causing a fire or explosion. As one of the core components of a new energy vehicle, the power battery provides electricity to ensure the normal operation of the electric vehicle, and whether it can be kept away from thermal runaway directly affects the safety, service life, charge and discharge times of the power battery. How to keep the battery away from thermal runaway is a common concern of new energy vehicle users. To this end, TRUMONY has compiled the following methods to ensure the safety of the power battery and avoid thermal runaway from happening. 1. Adopt liquid cooling technology The liquid cooling system can be highly integrated with the battery pack, easy to install on site, occupying a small area, without worrying about dust, water vapour condensation and other problems. In the event of a thermal runaway, liquid cooling solutions can rely on a high flow of cooling media to force the battery pack to dissipate heat and redistribute heat between battery modules, which can quickly inhibit the continuous deterioration of thermal runaway and reduce the risk of runaway. Liquid-cooled panels, which are more commonly used in new energy vehicles, work by transferring excess heat generated by battery operation through contact with the surface of the plate type aluminium device. The liquid-cooled system uses the large heat transfer coefficient of liquid flow to transfer high levels of heat, which is eventually carried away by the coolant passing through the internal flow channels of the device. 2. Battery Management System A battery management system (BMS) is a system that monitors the status of the battery. It monitors parameters suc

The development of the stamping process in the automotive industry

The automotive stamping process is one of the most important and time-consuming steps in automotive manufacturing. The automobile mainframe includes four major processes: stamping, welding, coating and general. Among them, the stamping process can be basically divided into the parts of drawing, punching, trimming and shaping. Depending on the structural characteristics and complexity of different parts as well as the process characteristics of the vehicle company, the forming process varies from 4 to 6 course sequences. With the continuous development of the automotive industry, the stamping process is also being optimised and upgraded. Firstly, there is automation. Automation in the form of robots, automated guided vehicles and other machines will reduce the need for manual labour, resulting in faster production, more precision and fewer errors, and a better grasp of precision and quality throughout the stamping process. At present, the stamping line with the highest production speed is the German servo press line, with a continuous production speed of up to 17 times/minute for the whole line, while the domestic Jiji line can also reach 13 times/minute, which means lower production costs and higher profits. So 17 times/minute is certainly not the limit, and the future will certainly be towards higher production efficiency. At the same time, as consumers' personalisation needs become stronger and stronger, model changes are becoming more and more frequent, so the future of mould flexibility. Low cost is the main direction of development in the future. In addition, the speed and efficiency of stamping processes will increase in the future. new technologies such as 3D printing and laser cutting will enable more precise and faster production, less scrap consumption and, above all, greater flexibility, meaning that moulds can be dispensed with and individualised. This will allow manufacturers to produce parts quickly, reducing waiting times

Do you know what are the main components of an EV power pack?

Power packs are the only source of power for purely electric vehicles and the range that an electric vehicle can travel depends on the power of the pack. The market is using high capacity cells or using more cells as a way of boosting the power pack electrical energy, however this can drive up the cost of the pack, so the focus needs to be on optimising the structure of the pack during the design process of the power battery, so what are the main components of an EV power pack? 1. Power Cell Module The role of the power battery module in the power pack is to store and release energy, which is the power source of the electric vehicle. The power battery module can be understood as the power battery monomer combined into multiple PACKs through series-parallel connection, PACK is a single component, which means packaging, encapsulation and assembly, and its process procedure includes three major parts: processing, assembly and packaging. After the power battery module has been structurally designed, it can be combined with the power battery management system and thermal management system to form a more complete power battery pack. The power battery pack is designed in a fixed position with the help of technology and structure, and together they play the function of electrical energy charging and storage. The fundamental role of the module is to fix, connect and secure the pack. Power battery cells and batteries are divided by positive materials, including lithium cobaltate, lithium manganate, lithium iron phosphate and lithium nickel cobalt manganate ternary materials.

BTMS Simulation

Definition of Simulation. Finite Element Analysis (FEA) uses mathematical approximation to simulate real physical systems (product models, loads, working conditions). It decomposes the model into a limited number of interconnected sub-regions, namely units, and uses a limited number of units to approximate the real system, and simplifies the original complex system to obtain an approximate solution that can meet the requirements of engineering applications and scientific research. How simulation works in product development A product, from conceptual representation to drawings, models, to the actual product landing, needs to consider a variety of different materials, numerous production processes, or simple or complex production processes. The transition from unstable samples to stable and reliable batch products that can adapt to production changes requires a large number of tests and verifications that meet design parameters. Design and selection of materials, manufacturing and processing, testing and verification, each stage is accompanied by the consumption of time, manpower and material resource. The simulation can test the performance of the product under different conditions by modeling the product model, loading different material parameters and environmental conditions. The product materials required for actual production, the production process of actual operation, and one or more experiments, which are originally in reality, are moved to the computer in a simulated way, and after simulation, we will get the required data result. Through the simulation-aided design and development, the pre-design of the product can be effectively demonstrated, and the loss caused by the design error can be avoided. Simulation can guide design and e

What is Battery thermal management?

Power battery is the core component of energy storage for new energy vehicles. It has relatively high requirements for working temperature. If the temperature is too high or too low, it will affect its performance and service life. Tests have shown that when the power battery is continuously charged and discharged at a charging speed of 1c for more than 50 times in an environment above 55°C, the battery capacity will be significantly reduced, and the battery life will be shortened accordingly. When the ambient temperature exceeds 60°C, the battery will have the risk of overheating, burning and explosion due to excessive temperature rise. Therefore, controlling the battery temperature so that it can work in a relatively better temperature range is an important part of new energy vehicle battery management. The power battery of a new energy vehicle contains a large number of battery cells, like the power battery pack of a Tesla electric vehicle, which is composed of more than 7,000 batteries. The battery has internal resistance. When charging and discharging, there is current flowing inside the battery, so it will generate heat and increase the temperature of the battery. With so many batteries, if the heat generated during their work is not managed, and the heat is not released in time, it is likely to cause the battery to run out of thermal control, shorten the battery life, and even cause a combustion accident. At present, there are four main ways for battery manufacturers to dissipate heat from batteries, namely, natural heat dissipation, air-cooled heat dissipation, liquid-cooled heat dissipation, and refrigeration heat dissi
