Problems solved by technology

However, the disadvantage of the above solution is that when a large current passes through a large current control device, heat loss will be generated, which will reduce the energy efficiency of the entire system
At the same time, in the process of turning on or turning off the high current, a surge of high current will be generated, which will damage the battery management system
In addition, the high current control device itself frequently turns on or off the high current, which will reduce its life

Abstract

A battery management system is used for determining whether a battery device is enabled to supply power for a load. The battery management system comprises a discharging return circuit and a main discharging control module. The discharging return circuit is used for achieving connection between the battery device and the load. The main discharging control module is used for detecting the state of the battery device and producing corresponding control signals when the battery device is in an abnormal state, so that the load is forced to stop working and then the load is forced to cut off the electrical connection between the battery device and the load in an initiative mode. Therefore, the battery management system is simple in structure, low in cost and high in reliability due to the adoption of dual protection of the main discharging control module and an auxiliary discharging control module.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a battery management system and a corresponding electronic system. Background technique [0002] In the process of battery application, because loads, such as high-power electric motorcycles, etc., usually require high current to work, therefore, in the process of turning on and off the high current, it will produce current shock and large heat consumption , In addition, it will also damage the large current control device. [0003] The current main solution is to use large relays or contactors to directly turn on or off large currents. However, the disadvantage of the above solution is that when a large current passes through a large current control device, heat loss will be generated, which will reduce the energy efficiency of the entire system. At the same time, during the turn-on or turn-off process of a large current, a surge impact of a large current will be gen...
