Leiditech recommends protective devices and schemes for automobile Charging station
The Charging station is generally composed of charging module, power device, IGBT module, filter, relay, display screen, etc. The input end of the Charging station is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. When the charging system is working, the main circuit and the control circuit interact to realize the safe, fast and intelligent charging function of the Lead–acid battery.
People can perform corresponding charging methods, charging times, and other operations by scanning the QR code. The GPRS communication module communicates with the MCU through UART to achieve data upload. The display screen can display data such as charging amount, cost, and charging time. The voice module can prompt the user about the charging situation.
IGBT module plays a vital role in Charging station, and is the core technical component of Charging station and other equipment. IGBT module accounts for about 20% of the cost of Charging station. IGBT module is used as switching element in Charging station.
IGBT combines the advantages of GTR and MOSFET, and has good characteristics. IGBT module is applied in the control circuit of Charging station: mainly composed of DSP controller, extended RAM, IGBT drive protection circuit, IGBT temperature monitoring circuit, Depolarization discharge circuit, three-phase current and voltage monitoring circuit, battery status monitoring protection circuit, etc., with the purpose of realizing intelligent charging.
