Improving the efficiency of new energy vehicles through thermal management

In the past, people measured the world with their feet, but now they travel around the world with their wheels. With the development of technology, the automotive industry is developing rapidly, especially the development of new energy vehicles. With the accelerated landing of new energy vehicles and the continuous improvement of battery energy density, higher requirements have been put forward for thermal management. The continuous singing of new energy vehicles is inseparable from the unstoppable technological development behind them.

Summary of the Development of Thermal Management Industry

With the development of electrification and intelligence in automobiles, electric vehicle thermal management systems are also moving towards integration, intelligence, and precision. The higher the integration level of thermal management system design, the higher the requirements for control logic. For electric vehicles, thermal management systems not only affect the driving comfort of passenger cars, but also involve the issue of range. How to achieve a balance between driving range and comfort in the actual environment of electric vehicles is one of the problems that need to be solved in the design of electric vehicle thermal management systems.
With continuous technological and structural updates, the thermal management industry is developing rapidly, and the development of electric vehicle thermal management system technology is also driving the development of the new energy vehicle industry in the opposite direction.

One stop solution for assembly and testing of automotive thermal management products

The rapid development of the new energy vehicle industry is also a continuous challenge and a great challenge for equipment manufacturers in the industry chain. As an integrator of a one-stop assembly and testing production line for automotive thermal management products, Zhongke Motong follows the development path of the industry, continues to innovate, and empowers the upgrading of the thermal management industry.
At present, Zhongke Motong has rich project experience in the thermal management industry, with advanced intelligent assembly lines such as integrated module assembly lines, electronic water pump assembly lines, electronic water valve assembly lines, electronic expansion valve assembly lines, electric compressor assembly lines, and third-generation EOL testing technology.

From traditional to new energy, thermal management opens up new space

Fast charging of batteries puts forward higher requirements for thermal management. With fast charging, the heat generation of batteries increases, leading to an increased demand for thermal management. During fast charging, it is necessary to heat the battery cell in advance, but too high a temperature can exacerbate the aging of the battery cell. Therefore, a thermal management system is needed to ensure that the battery cell is within a reasonable temperature range.
Heat pump air conditioning is gradually replacing pure PTC, increasing range
Heat pumps consume less energy than PTC, increasing the range of electric vehicles. PTC heating uses direct conversion of electrical energy into heat, which is then fed into the passenger compartment by an electronic fan, resulting in high electrical energy consumption. Heat pump heating uses refrigerant to absorb heat outside the vehicle through a heat exchanger, and brings the heat into the vehicle to provide heating. Compared to PTC heating, it has lower electrical energy consumption and can significantly increase the range of electric vehicles. However, its heating effect is poor in low-temperature environments. Heat pumps consume less energy than PTC, increasing the range of electric vehicles. Taking Model 3 as an example, compared to PTC heating method, the average power consumption of heat pump air conditioning per 100 kilometers is reduced by 2.2-2.5 kWh. Assuming a battery capacity of 50 kWh, it can increase the range by about 35 km, an increase of 14%.
The thermal management of the entire vehicle not only involves the use of air conditioning in the passenger compartment, but also takes into account the heating and insulation or cooling of the components of the vehicle, as well as the thermal energy management of the entire vehicle system. The key to thermal management is the "three major components" of thermal management - heat pumps (integrated modules), electronic water pumps, and water valves. For the "three major components" of thermal management, Comoton also has rich experience in automation equipment projects. Regarding water pumps, water valves, and integrated modules... please wait for the continuous updates of the thermal management thematic series.
