Abstract

The invention discloses a dual-protection system and method for batteries. The dual-protection system comprises a hardware protection module, a software protection module, a drive module, a current sensing resistor and a protection switch, wherein the current sensing resistor is electrically connected with the negative electrode of a battery pack and then connected with the protection switch in series; the input end of the hardware protection module and the input end of the software protection module are electrically connected among the positive electrodes of all the batteries in the battery pack, the protection switch and the current sensing resistor, the output end of the hardware protection module and the output end of the software protection module are electrically connected with the input end of the drive module, and the output end of the drive module is electrically connected to the control end of the protection switch to control the protection switch to be turned off. The dual-protection system and method can improve the reliability of the battery pack and reduce the accident probability of the battery pack.

Description

technical field [0001] The invention relates to the technical field of battery protection, in particular to a battery double protection system and method. Background technique [0002] At present, the functions and computing power of various electronic devices are getting stronger and stronger. In order to ensure the reliable and stable operation of electronic devices, they are usually equipped with reliable and stable power supplies. In the field of communication, communication power supply, transmission equipment and switching equipment are the key equipment in the communication system. Taking the communication base station as an example, the communication power supply generally includes an AC power supply subsystem, a DC power supply subsystem, a distribution subsystem and a grounding subsystem, and both the AC and DC power supply subsystems require a backup power supply. The backup power of the AC power supply subsystem generally adopts an uninterruptible power supply s...
