The electronic control system, often referred to as the brain of a new energy vehicle, is one of the three core technologies and primarily encompasses the motor control system and battery management system. A new energy vehicle's electronic control system generally includes the following components:
Battery Management System (BMS): Responsible for monitoring and managing the status of the battery pack, including charge, temperature, voltage, etc., and protecting and balancing the batteries.
Motor controller (MCU): controls the operation mode and output power of the motor, and outputs the corresponding drive torque according to parameters such as vehicle speed and acceleration.
On-board charger (OBC): Responsible for converting the AC power from an external power source (such as a charging station) into the DC power required by the battery for charging.
Auxiliary Power System (APS): Provides the necessary auxiliary power for the entire electronic control system, including power supply for equipment such as air conditioning and audio equipment.
Automotive network communication system: A communication system between various components used to transmit control commands, sensor data, and other information.
Interface and display system: Provides a human-machine interface, including a central control screen, a handle, etc., to facilitate driver operation and control.
These components work together to enable the electrification of new energy vehicles and achieve efficient use and conservation of electrical energy. From large-scale functions such as temperature management, charging load balancing, and vehicle acceleration and deceleration, to smaller functions such as air conditioning control, kinetic energy recovery management, and fuel injection, everything is controlled by the electronic control system. In short, the electronic control system actually determines how a car drives.
