Abstract

The invention belongs to the technical field of power battery control, and in particular relates to a battery pack control circuit and a battery pack control system. The battery pack control circuit includes: a connector connected to a battery management system for connecting the battery The management system transmits the charge and discharge control signal, and transmits the switching control signal to the control switching circuit; the battery management system, the battery management system is powered by a battery pack, and is used to control the on-off of the switching circuit; the control switching circuit, the The control switch circuit is used to realize the control switch of the switch circuit according to the switch control signal; and the switch circuit is used to control the charging and discharging of the battery pack. The battery pack control circuit provided by the present invention can prevent the problem that the forklift suddenly loses power due to external power failure affecting the power supply of the electric management system, and ensures the stable power supply of the battery pack during the operation of the forklift.

Description

technical field [0001] The invention belongs to the technical field of power battery control, and in particular relates to a battery pack control circuit and a battery pack control system. Background technique [0002] In recent years, battery power systems have been widely used in industries, transportation, shopping malls, banks, public security and smart residential quarters, and are an important part of modern power systems. [0003] Generally speaking, the power battery system consists of the following parts: battery pack, BMS (abbreviation for BATTERY MANAGEMENT SYSTEM), electrical circuit; some systems also include heating and cooling devices. Usually, the power battery system must have a complete charge and discharge control circuit. Once an abnormal situation occurs at the alarm point, the power battery system BMS can automatically cut off the circuit and store the alarm record. [0004] However, in the existing power battery control system, an external power suppl...
