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.
本发明公开了一种电池高压检测装置、电池、动力系统及汽车,电池高压检测装置包括:彼此分离设置的高压检测模块和主控制器。高压检测模块包括:采集电路、从控制器和第一无线通讯模块。采集电路采集电池的高压回路的电信号,并将电信号转换为数字信号并传送至从控制器。主控制器具有第二无线通讯模块,第二无线通讯模块接收来自第一无线通讯模块的数字信号。由于电池高压检测装置将高压检测模块和主控制器设置于不同的电路板上,这种结构的设置相比于将高压检测模块和主控制器设置于同一个电路板上的方式而言,避免了高压检测模块对主控制器的电磁干扰。使得主控制器计算出的高压回路的电压值也较为精准,保证了汽车的安全稳定运行。
