Multi-battery pack hot plug management system and method

The invention discloses a multi-battery pack hot plug management system and method, the system comprises an MCU, one or more batteries, battery control output circuits, a battery voltage sampling circuit and a load circuit, each battery is correspondingly provided with a battery control output circuit, and the battery control output circuit comprises a battery control output circuit A and a battery control output circuit B; and the MCU performs on-load voltage detection on each battery in a time-sharing manner by using a quick polling mode so as to judge whether the voltage of the battery meets the discharge requirement, and if the voltage meets the discharge voltage requirement, the MCU controls the corresponding battery control output circuit to conduct and discharge. The system solves the problem of lack of an intelligent management system in the application of a multi-battery hot plug technology, can effectively manage the discharge and access of the batteries of the battery pack, facilitates the circuit
