Abstract

The invention discloses a balancing application device and method for a chargeable battery pack. The device includes a plurality of temperature current acquisition modules, a plurality of digital potential regulators and a data acquisition and processing unit. According to the device and method for balanced application of the chargeable battery pack provided by the above technical schemes of the invention, application environments which tend to be consistent with each other can be maintained for batteries in a use process, and therefore, problems of uneven heat discharge and increasingly-large inner resistance difference of the batteries under different current can be solved, and the performance of the batteries can be maintained, and the service lives of the batteries can be prolonged. The device and method have a broad market prospect in popularization.

Description

technical field [0001] The invention relates to the field of new energy vehicle power rechargeable lithium battery packs, in particular to a device and method for balancing application of rechargeable battery packs. Background technique [0002] Since its launch in the 1990s, lithium-ion batteries have achieved unprecedented development in just over a decade due to their unique properties, and have been widely used in portable devices such as mobile phones, notebooks, and digital cameras. With the gradual improvement of the safety and cost performance of lithium-ion batteries and the continuous breakthrough of group technology, lithium batteries have gradually entered high-power applications, such as electric vehicle power sources, communication system backup power, railway auxiliary power and power system backup power, etc. Especially in the field of electric vehicle applications, the demand for lithium batteries is growing rapidly, and will gradually replace traditional le...
