Problems solved by technology
The above-mentioned batteries are composed of a number of single cells to form a battery module, and are connected in series when installed on the electric vehicle to achieve the application voltage of the electric vehicle. However, as the number of charging and discharging of the battery increases, the The inconsistency of single battery parameters will gradually increase, and as a result, the output capacity of the battery module will gradually decrease, and the service life of the battery will be reduced, which will become a major problem restricting the practical application of new batteries

The invention discloses an electric switch type automatic equalization battery module comprising a module shell, a temperature detecting device, battery pack groups, a battery module status indication device and an electric equalization switch device, wherein the electric equalization switch device comprises an equalization switch base and an equalization switch contact group; the equalization switch base is provided with an insulated pull rod in which a spring plate slot is formed; the equalization switch contact group is provided with a moving contact spring plate arranged in the spring plate slot; the insulated pull rod is connected with a pull rod driving device. The electric switch type automatic equalization battery module has the beneficial effects that firstly, the battery pack groups of the module are in a serial connection status during normal work so that the requirement for output voltage of the battery module is met; secondly, when equalization is required, the serial connection status of the contact group is disconnected and is rapidly converted into a parallel connection status, so that battery monomers in the battery pack groups are kept equalized.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to an electric switch type automatic balancing battery module suitable for electric vehicles. Background technique [0002] In recent years, new energy electric vehicles have developed rapidly, and the power supply system, control system and power system have become the three core technologies of new energy electric vehicles, among which the power supply system is the key core technology for the application of new energy technologies. Traditional lead-acid batteries, due to the heavy weight of lead-acid batteries, short service life, and inability to achieve fast charging, have restricted the development of new energy electric vehicles. [0003] The above-mentioned batteries have the characteristics of light weight, long-lasting mileage, long service life, and fast charging, and are bound to replace traditional lead-acid batteries in the application of new energy electric vehicles...
