Abstract

The invention discloses a system and method for parallel charging and balancing management of multiple cell modules. The system comprises a direct-current bus and multiple parallel cell modules. The positive electrodes of the cell modules are connected with the positive end of the direct-current bus, and the negative electrodes of the cell modules are connected with the negative end of the direct-current bus. The system also comprises a main control unit. Each of the cell modules comprises a cell unit, a balancing unit and a sampling unit. The sampling units are connected with the main control unit. The beneficial effects are that parallel charging and rapid and highly-efficient balancing management of the multiple cell modules can be achieved and charging efficiency and balanced charging efficiency are effectively improved.

Description

technical field [0001] The invention relates to a battery charging management method, in particular to a multi-battery module parallel charging and balancing management method. Background technique [0002] With the continuous promotion and development of drones in various fields, the application of high-rate batteries is becoming more and more common. However, during the high-current discharge process of high-rate batteries, as the number of cycles increases, the capacity difference between single cells and between battery packs becomes larger and larger. If sampling the traditional charging method, it will seriously affect the battery capacity. Module charging speed, user experience and service life. This poses a new challenge to the battery module charging method, that is, how to realize fast and intelligent multi-battery module parallel charging and cell balance management. [0003] Many of the existing battery pack chargers use a one-to-one mode, without equalization ...
