Abstract

The present invention provides a battery module assembly system, including a plurality of standard battery modules and a battery management system host computer; wherein, the battery management system host computer is connected to the communication interface of the standard battery module; A battery pack is formed through series connection, parallel connection or series-parallel hybrid connection; any one of the standard battery modules has a mechanical structure; adjacent standard battery modules are detachably connected through the mechanical structure. The standard battery module in the present invention has a circuit breaker and a soft start circuit, which can ensure the safety of each standard battery module, which is superior to the integrated battery pack in the prior art, and can only perform circuit breaker protection for the entire battery pack, while the battery module does not have The circuit breaker function cannot switch the battery module.

Description

technical field [0001] The present invention relates to a battery pack, in particular to a battery module combination system. Background technique [0002] Electric vehicles, solar energy storage devices, wind power generation energy storage devices, electric energy peak-valley adjustment devices and other power generation or power-driven equipment mostly require power storage. Most of the power storage devices use battery modules, such as lithium batteries, nickel For hydrogen batteries, lead-acid batteries, etc., energy storage devices are composed of dozens to hundreds or thousands of batteries in series or in parallel to achieve the required voltage and power. [0003] Usually, the capacity of the battery cells is expanded by parallel connection. After the battery cells are connected in parallel, the voltage remains unchanged and the battery capacity increases. By changing the number of parallel connections, the required capacity is achieved. Single cells extend the vol...
