AI Technical Summary
In high-altitude and frigid environments, the charging and discharging management and control of lithium batteries cannot ensure their safety and service life, and the low-temperature discharge capacity of lithium batteries is insufficient to meet the starting and combat readiness requirements of special vehicles.
A lithium battery charging matching control circuit based on high-altitude and cold environments was designed, including a lithium battery, a power generation system, a main distribution box, an external power interface, diodes and cables. The circuit adjusts the excitation current and controls the contactor through the generator controller to achieve charging current management of the lithium battery under different temperature conditions and provides an emergency power supply interface.
It improves the safety and lifespan of lithium batteries, ensures the stability of the power grid, meets the starting and combat readiness needs of special vehicles in high-altitude and cold environments, and provides reliable emergency power supply.
