At present, the leading Oems have derived second and third generation technologies for motor thermal management, battery thermal management and cockpit thermal management, and each generation of technology has higher requirements for software and hardware integration. Taking the active liquid cooling technology of motor thermal management as an example, in order to quickly cool the motor, the on-board computer needs to adjust the coolant flow in the loop according to the preset program, and can decide whether to series the battery loop and motor loop through the four-way valve according to the battery pack heat, in order to achieve more efficient integrated thermal management control.
At present, major Oems are also constantly researching and upgrading thermal management systems. For example, the most typical Tesla Model Y thermal management system, Model Y is the fourth generation of Tesla thermal management system, using a new heat pump air conditioning system, can achieve a variety of modes of thermal management.
Byd new energy vehicles also have certain achievements in thermal management technology, pure electric models Han, Tang battery thermal management system using water cooling heat exchange, the use of air conditioning system electronic expansion valve and battery pack cooling, can meet the different priorities of air conditioning and battery cooling; Byd has also developed direct-cooling and direct-heating technologies for battery packs and enthalpy heat pumps, which allow cars to heat at lower temperatures.
The Toyota CHR EV, Prime Battery thermal management system uses air circulation through the air conditioning system evaporation box and blower to cool the power battery, and the heating system uses 12V lead battery power. In addition, GAC Aion V Plus, Geely Geometry G6, Xiaopeng P7i, Zero Run C11, Ideal L9 and the Q Jie M9 released in December all have their own thermal management technology, so thermal management is quite valued by the Oems.
