The embodiment of the invention provides a battery module control method and system, when a preset charging condition of a battery module is met, a main control module sends a battery wake-up signal to a valve control module, and sends a charging start signal to an energy control module and a power supply module. And the valve control module controls the first relay to be closed to trigger the battery module to enter an activated state. And the energy control module controls the second relay to be closed, and the power supply module is connected with the battery module. And the power supply module outputs current to the battery module. And the main control module sends a battery dormancy signal to the valve control module and sends a charging stop signal to the energy control module and the power supply module when charging of the battery module is completed. And the valve control module controls the first relay to be disconnected to trigger the battery module to enter a dormant state. And the energy control
