Embodiment Construction

[0009] refer to figure 1 , The device of the present invention mainly includes a central processing unit 1 , an internal resistance capacity measurement module 2 , an expert database module 3 , a sampling module 4 , an online balance activation module 5 and a storage battery management module 6 . In addition, it may also include various communication components, man-machine operation components, and the like.

[0010] Central processing unit 1 is the main part of this device data processing and control. The sampling module 4 is used to collect the parameters of the battery pack and each single battery. The battery management module 6 can control the connection and disconnection of each single battery.

[0011] The internal resistance capacity measurement module 2 is used in conjunction with the expert database module 3 to measure the internal resistance capacity of the storage battery. The expert database module 3 stores the calculation data based on the one-to-one correspon...

Abstract

The invention discloses a storage battery on-line balanced and activating device based on handshaking technology communication. The storage battery on-line balanced and activating device comprises a central processing unit, an internal resistance measuring and calculating module, an expert database module, a sampling module, an on-line balanced and activating module and a storage battery management module. The central processing unit sends communication orders through software handshake and controls simultaneously through hardware handshake; the modules send responses to the central processing unit after receiving orders, and perform relative functional process; and the modules send the hardware handshake to the central processing unit after functional process is finished, and the central processing unit decides whether to communicate with the modules or not according to data busy degrees and utilizes the software handshake to send relative responsive orders to the modules. With the storage battery on-line balanced and activating device, each function can be integrated effectively and can be combined and point-to-point managed simultaneously, unstable operating conditions of intelligent storage battery set maintenance devices are eliminated, and overall back-up source system break down caused by instability in maintaining of storage batteries by the intelligent storage battery maintenance devices can be avoided.

Description

technical field [0001] The invention relates to the technical field of storage battery operation, in particular to an online balancing and activating device for storage battery packs based on handshake technical communication. Background technique [0002] At present, a charger is widely used to charge a group of battery packs in series online. When one of the batteries in the battery pack is activated or necrotic, we often have to replace the entire battery pack. This charging method cannot guarantee the balanced charging of each battery in the battery pack, and the battery is often overcharged or undercharged due to the change (higher or lower) of the terminal voltage of a certain battery in the battery, the increase in internal resistance, and the decrease in capacity. Long-term overcharging or undercharging greatly reduces the performance and service life of the battery pack. Therefore, maintaining the stability of the battery pack, keeping the voltage, internal resista...
