The invention provides a vehicle-mounted low-voltage lithium battery control system and method, and belongs to the technical field of low-voltage lithium batteries, and the method comprises a low-voltage lithium battery module which is used for obtaining lithium battery data and controlling a main loop switch to be switched off or switched on based on a control instruction, and a data conversion unit which is in communication connection with the low-voltage lithium battery module and is used for converting the data into data. The data conversion unit is used for receiving the lithium battery data, sending the lithium battery data to the whole vehicle domain control system, receiving a control instruction sent by the whole vehicle domain control system and forwarding the control instruction to the low-voltage lithium battery module, and the whole vehicle domain control system is in communication connection with the data conversion unit and used for matching the lithium battery data with a preset threshold value, determining the charging and discharging state of the lithium battery and sending the charging and discharging state to the low-voltage lithium battery module. And generating a corresponding control instruction based on the charging and discharging state. The technical problems that in the prior art, a battery management system in a low-voltage lithium battery is complex, and the maintenance cost is high are solved.
