Abstract

The invention provides a control system for realizing parallel-connection circulating charging of multiple sets of lithium batteries and a method of the control system. The control system at least comprises a charger, the multiple sets of lithium batteries, a charging loop and a communication line set, wherein the multiple sets of lithium batteries and the charger are connected in parallel through the charging loop, and the charger communicates with each lithium battery through the communication line set. The control system for realizing parallel-connection circulating charging of the multiple sets of lithium batteries and the method of the control system can guarantee that each set of lithium batteries is fully charged with electricity under an unattended condition, can obviously reinforce the durability of the lithium batteries, prolong the recycling service life of the battery packs, and meanwhile obviously improve the utilization rate of the charger on the premise of not increasing the control complexity of a charging system and development cost.

Description

technical field [0001] The invention relates to a control system and method for battery charging, in particular to a control system and method for realizing parallel cycle charging of multiple groups of lithium batteries. Background technique [0002] With the continuous development of microelectronics technology, miniaturized equipment is increasing day by day, so higher requirements are put forward for the power supply used. Lithium batteries have the advantages of high energy, long service life, high rated voltage, high power tolerance, low self-discharge rate, light weight, and environmental protection, so they are widely used in mobile phones, notebook computers, electric vehicles and other miniaturized devices . Accordingly, there is a need to provide a more efficient and faster lithium battery charging method. [0003] At present, the charging method of lithium battery is mainly for charging a lithium battery. If a single set of multiple lithium batteries is charge...
