Lithium battery system monitoring single board testing device

The utility model relates to a lithium battery system monitoring single board testing device which comprises a shell, and an all-in-one machine tool mainboard testing module, a current simulation board testing module, an LED board testing module, a power supply module and a display screen are installed in the shell in a matched mode. Wherein the all-in-one machine tool mainboard test module is used for simulating four-path DI signal reception or four-path DO output signals, the current analog board test module is used for simulating current output signals to test a current detection circuit of a monitored single board to be tested, the LED board test module is used for testing a dry contact of the monitored single board to be tested, and the power supply module is used for providing a matched power supply for other modules. The multi-channel automatic testing device can support multi-channel automatic testing and automatically judge and output testing results, is simple in structure and convenient to operate,
