The invention provides a series-parallel connection switching device and a battery pack comprising the series-parallel connection switching device. The series-parallel connection switching device comprises a series connection switching module and a parallel connection switching module. The series switching module connects the first battery module, the second battery module and the third battery module in series to form a battery module, and the parallel switching module connects the plurality of battery modules in parallel. A detection module is respectively connected with the first battery module, the second battery module and the third battery module, the detection module is connected with the controller, and the controller is respectively connected with the series switching module and the parallel switching module. According to the series-parallel connection switching device disclosed by the invention, the series connection relationship of a plurality of battery modules in the battery module can be changed; or the parallel connection relationship of a plurality of battery modules outside the battery module is changed, so that the voltage regulation or the capacity regulation ofthe whole battery pack is realized to adapt to chargers with different capacities and voltages, the influence of the damaged battery module on other battery modules is avoided, and the use efficiencyof the whole battery pack is improved.
Description
technical field [0001] The invention belongs to the technical field of series-parallel switching, and in particular relates to a series-parallel switching device and a battery pack including the series-parallel switching device. Background technique [0002] At present, new energy power lithium battery vehicles are constantly developing at a high speed. The car battery is composed of multiple battery modules connected in series and parallel. During the use of the vehicle, the power battery will inevitably fail, such as a lot of power reduction and part of the battery damage, and The capacity and voltage of batteries produced by different manufacturers are different, and the battery may encounter mismatched capacity and voltage chargers during charging, which will limit the driving of the car. Contents of the invention [0003] In order to solve the shortcomings of the prior art, the object of the present invention is to provide a series-parallel switching device and a batt...
