| description | The invention discloses a low-voltage lithium battery pack battery management system. The system comprises a power supply module, a current sensor signal sampling module, a switching value acquisitionmodule, a load relay driving module, a charging relay driving module, a temperature management relay driving module, a communication module, a single voltage sampling module, a module temperature acquisition module, a passive equalization module, a voltage monitoring module, an MCU module and a crystal oscillator module. The structure is simple, stable and reliable, the voltage consistency of thesingle battery cells is ensured, and meanwhile, single-battery overvoltage is avoided; sampling of voltage and resistance values is facilitated; the voltage value acquisition and calculation principle is simple, the cost is low and the reliability is high; connection and disconnection control of each load loop can be realized; heat dissipation or heating of a matched lithium battery pack is actively realized; and when ove |
