Abstract

The invention discloses a battery high-voltage detection device, a battery, a power system and an automobile. The battery high-voltage detection device comprises a high-voltage detection module and amain controller which are separated from each other. The high-voltage detection module comprises an acquisition circuit, a slave controller and a first wireless communication module; the acquisition circuit acquires an electric signal of a high-voltage loop of the battery, converts the electric signal into a digital signal and transmits the digital signal to the slave controller; the main controller is provided with a second wireless communication module, and the second wireless communication module receives the digital signal from the first wireless communication module. Due to the fact thatthe high-voltage detection module and the main controller are arranged on different circuit boards of the battery high-voltage detection device, compared with the mode that the high-voltage detectionmodule and the main controller are arranged on the same circuit board, electromagnetic interference of the high-voltage detection module to the main controller is avoided. Therefore, the voltage valueof the high-voltage loop calculated by the main controller is accurate, and safe and stable operation of an automobile is guaranteed.
