To solve the problems of online monitoring system for high-voltage battery pack in series, this paper states the design of a practical interface circuit. The circuit consists of PhotoMOS, MCU and electrical switch. The PhotoMOS controlled by MCU could connect the measuring battery to measuring circuit, meanwhile the other batteries are physically isolated from the measuring circuit, and has no influence to the measuring circuit. This method effectively lowers the complexity of circuit, and improves measurement precision. |
