A power supply starting system for a lithium battery with automatic preheating function comprises a lithium battery 101, an output module 103 and output control module 102, a working power supply control module 104, a CPU master control module 105, an operation panel display function module 106, a heater module 108 and heater control module 107, an information sampling module 109 and a charging module 110, wherein the CPU master control module receives information from the sampling module, estimates real-time residual capacity of the battery and sends alarm information or a switching off instruction when abnormal voltage change occurs, distinguishes the connection status of an external battery apparatus and sends a corresponding instruction or a switching off message to the output control module when an error occurs, estimates the temperature of the battery and in the event of an anomaly in battery temperature raises an alarm or drives the heater control module to start heating and adjusts the heating power and total heating time with reference to the residual capacity of the battery. |
