Boost grouping method of storage battery module and boost grouping controller of storage battery module

Abstract

The invention discloses a boost grouping controller of a storage battery module. The boost grouping controller consisting of a storage battery module composed of a plurality of single storage batteries, a super capacitor, a discharge switch current-limiting voltage regulator, a charge switch current-limiting voltage regulator, a DC-DC (direct-current-direct current) power supply booster, a storage battery module monitor, a pulse transformer, a rectifier, an output power supply filter, a temperature regulator, a storage battery module charging and temperature regulation controller, a storage battery module charging and discharging controller and a micro controller. According to the invention, an operation method of storage battery module boost grouping is realized, thus the storage batterymodules can be isolated mutually and operate individually after grouping, the mutual influence of the storage battery modules after grouping can be avoided, the service life of a storage battery set is improved, and the boost grouping controller has the characteristic of convenience in implementation.

Description

technical field [0001] The invention relates to a battery module boosting group method and a battery module boosting group controller, which belong to the technical field of battery control. Background technique [0002] In the existing storage battery grouping method, in order to meet the requirements of the load voltage, the battery cells and battery modules are combined in series to boost the voltage. Due to the current production technology and process limitations of the battery, each cell The consistency of the technical indicators of the battery is poor, so the single battery and the battery module affect each other in the process of charging and discharging after being connected in series, so that some batteries in the series battery group are easy to overcharge or overdischarge, resulting in a long working life of the battery group. It is more common in the application of lithium-ion batteries than the working life of the single battery and the battery module; in the...

[0002] In the existing storage battery grouping method, in order to meet the requirements of the load voltage, the battery cells and battery modules are combined in series to boost the voltage. Due to the current production technology and process limitations of the battery, each cell The consistency of the technical indicators of the battery is poor, so the single battery and the battery module affect each other in the process of charging and discharging after being connected in series, so that some batteries in the series battery group are easy to overcharge or overdischarge, resulting in a long working life of the battery group. It is more common in the application of lithium-ion batteries than the working life of the single battery and the battery module; in the existing technology and solution, it is used to connect a The balance and measurement and control branch, under the monitoring control of the microprocessor and the measurement and control branch, makes the external characteristics of the single batteries in series tend to be consistent, thereby improving the life of the series battery pack; the disadvantage of this is: the balance and measurement and control branch The effective working range of the road is limited, so when the index difference and change of the single battery is too large, it will still affect the life of the entire series battery pack. If the single battery is directly boosted independently and then grouped, because the single battery The voltage of the battery is relatively low, and the direct use of electronic technology to boost the voltage will result in a decrease in the efficiency of the output power
