For example, in the charging scenario, only the vehicle controller, battery management system, DCDC, water pump controller, etc. are in working state, and the motor controller does not need to be woken up, so that it can be managed by partitions and reduce power consumption. It is also possible to extend the use time of the controller. Figure 7. Working conditions of different domains under different power modes. Processor and Network Loading Another important architectural consideration is the loading of each controller’s processor, network bus, and gateway.
