Problems solved by technology
[0002] Traditional lithium-ion battery modules are mainly connected by bolts or welding. After processing, the battery module has been finalized, and its capacity, voltage, charge-discharge rate and other specifications cannot be changed. Therefore, the application of each module has great limitations. At the same time, the charge and discharge rate has been determined, and the charge and discharge time has also been determined, which is not suitable for occasions that need to change the charge and discharge time at any time

The present invention discloses a switch-type lithium ion battery module which comprises a battery module, an electrical driven switch base and an electrical driven switch upper cover, wherein the battery module consists of N lithium ion battery monomers, and is divided into at least two half battery modules; an anode and a cathode are respectively led out of each half battery module; the input end of the electrical driven switch base is respectively connected with the anode and the cathode of each half battery module, and the output end of the electrical driven switch base is used for outputting a voltage result after the plurality of half battery modules are connected in series or in parallel; the electrical driven switch upper cover is connected with the electrical driven switch base; and by regulating relative positions of the electrical driven switch upper cover and the electrical driven switch base, serial-parallel switching is implemented among the plurality of half battery modules. The switch-type lithium ion battery module has the advantages that a switch switching structure is applied to the lithium ion battery module, so that the battery module is switched among different serial-parallel numbers, thereby completing regulation on dynamic capacity, a voltage and a charge-discharge rate specification of the battery module and meeting different requirements for voltages, power, time and the like.
Description
technical field [0001] The invention relates to a lithium ion battery module, in particular to a switchable lithium ion battery module and a switching method thereof. Background technique [0002] Traditional lithium-ion battery modules are mainly connected by bolts or welding. After processing, the battery module has been finalized, and its capacity, voltage, charge-discharge rate and other specifications cannot be changed. Therefore, the application of each module has great limitations. At the same time, the charge and discharge rate has been determined, and the charge and discharge time has also been determined, which is not suitable for occasions where the charge and discharge time needs to be changed at any time. To this end, a Li-ion battery module with switchable dynamic specifications was developed. Contents of the invention [0003] The purpose of the present invention is to provide a switchable lithium-ion battery module and its switching method, which applies t...
