Automotive electronics

Companies of all sizes are using vehicle GPS positioning systems, and local governments and government agencies around the world are reducing operating costs and providing control over their most remote assets.

To maximize opportunities in a competitive growth market, one manufacturer is looking to improve GPS accuracy and reliability, in a standard solution that can span vehicles equipped with different vehicle battery systems. At the same time, the company needs to reduce the size of the system to simplify the installation. This increases the power level required by the design team by 33 %, and the available space is limited to the DC-DC converter printed circuit board. The design team is also looking for creative ways to save system battery life while improving the efficiency of power solutions. It is considered a potential area for improvement in light loading.

Description of the programme:

Electric vehicles mainly use batteries instead of fuel, provide energy to the motor, drive the operation of the car, and ensure the reliability of the system's work through the monitoring and management of the battery pack. Electric vehicles have the advantages of small environmental pollution, no noise, low noise, high efficiency, simple structure, and convenient use and maintenance.

Power supply:

The power supply module is mainly used in the IGBT in the motor drive, providing the driving power for the IGBT. At the same time, the BMS cell manages the information of the battery state and the drive voltage detection signal to isolate it, improve the accuracy of the system signal transmission, and ensure the safety of the use of electric vehicles.

Programme characteristics:

The BMS battery management system is the core of battery life in electric vehicles. It is achieved by monitoring the status of batteries and cells in the group in real time to control the charge, discharge, and other functions of the cells.
