Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0029] As mentioned in the prior art, the main components of the existing battery modules include a series and / or parallel connection of battery cells 110 such as lithium batteries, nickel-metal hydride batteries or a large battery such as a lead-acid battery, or a lithium-iron battery or Lithium iron phosphorus oxide battery, and other main batteries. Another main component is the battery management chip BMU. Most of them are charged through the CC-CV stage, and the CV stage is the most time-consuming, and the charged energy is not as good as the CC stage.

Abstract

The invention discloses a charging method for reducing the waiting time for charging and a battery module, the battery module at least comprises a main cell group used for providing the electric energy to load during discharging, a voltage conversion device, an auxiliary electric energy storing device, a battery management chip, wherein a first group control charge and discharge switch as well as a second group control charge and discharge switch are provided to the battery management chip, the first group control charge and discharge switch as well as the second group control charge and discharge switch respectively control the main cell group and the auxiliary electric energy storing device in an independent mode, when the battery module is charged by an external charger, the main cell group and the auxiliary electric energy storing device can be simultaneously charged, when the battery module disconnects the external charger, the auxiliary electric energy storing device is capable of continuously charging to the main cell group through the second group control charge and discharge switch as well as the voltage conversion device which can be taken as an internal charger, such as charging in a constant voltage mode can be carried out.

Description

technical field [0001] The invention relates to a battery module, in particular to a battery pack and method that can shorten charging waiting time, and standardize charging and discharging behaviors to improve charging and discharging safety. Background technique [0002] Today, with soaring oil prices and shouting for energy saving and carbon reduction for the effect of global warming, gasoline-electric hybrid vehicles, or electric vehicles, and electric vehicles have become the favorites that governments of all countries are trying to promote to their people. However, as far as "electric" vehicles are concerned, they must have a high-capacity battery, or at least a battery pack of multiple batteries connected in series or parallel. And the only way they can charge their internally stored electricity is by charging them with an indoor charger or an outdoor charging station. Instead of a gasoline and diesel engine driving a generator to generate electricity through a belt ...
