Abstract

The invention relates to the management of rechargeable batteries, and proposes a distributed battery management system and management method, including a battery pack data sampling module and a battery sampling management module. Sampling is performed, and the sampling value of each battery is output to the battery sampling management module, and the battery sampling management module responds to the output of at least two battery pack data sampling modules and performs corresponding processing. The battery pack data sampling module realizes the primary protection of the battery pack, and the battery sampling management module realizes the secondary protection of the battery pack. The invention has a good sampling speed, realizes real-time monitoring of a single battery or a battery pack, and realizes multi-level and fast battery protection response actions, and has low cost, so that mass production can fully meet requirements in terms of cost and performance.

Description

【Technical field】

[0001] The invention relates to a management system and a management method for sampling and managing the voltage, current, capacity and temperature of batteries, in particular to a distributed real-time management system and management method. 【Background technique】

[0002] With the increase of electric equipment, the application of rechargeable battery packs is becoming more and more extensive. During the application process of battery packs, it is necessary to monitor the battery packs and collect the current, voltage, temperature and remaining capacity of each battery. The sampling values ​​are compared and analyzed. When the situation exceeds the threshold range, the control protection module takes action to protect the battery.

[0003] The usual battery pack sampling management methods are the following two:

[0004] 1. Centralized battery pack management method, as shown in Figure 1. The advantage of this method is that the structure is relativel...
