A replaceable battery control system for electric vehicles

Abstract

The invention provides a changeable battery control system for an electric automobile and belongs to the technical field of electric automobile battery changing. The problems that the power capacity of a fixedly arranged battery pack is hard to guarantee and the battery life cannot be rapidly prolonged in the prior art are solved. The changeable battery control system for the electric automobile comprises a controller, an electronic switch module, a detachable first battery pack, a fixed second battery pack, a first charging module, a charging port and a discharging port; and through the electronic switch module, the discharging port is supplied with power by using the first battery pack and / or the second battery pack. The changeable battery control system for the electric automobile further comprises a second charging module; the second charging module is supplied with power by using the first battery pack and used for charging the second battery pack; and the controller is used for controlling the second charging module and the electronic switch module. According to the changeable battery control system for the electric automobile, the power capacity in the fixedly arranged battery pack is preferentially kept.

Description

technical field [0001] The invention belongs to the technical field of battery exchange for electric vehicles, and relates to a control system for a replaceable battery of an electric vehicle. Background technique [0002] Based on the requirements of environmental and energy factors, new energy vehicles are the main direction of development now, and electric vehicles are the main force of new energy vehicles. The length and replenishment of mileage are major factors restricting the development of electric vehicles. Current electric vehicles generally have problems such as time-consuming mileage replenishment and short cruising range. [0003] At present, there are three main ways to solve the mileage of electric vehicles. One is to improve the mileage of new energy vehicles by developing battery technology and increasing the energy density of batteries; the other is to realize the improvement of mileage by developing fast charging. Quick replenishment, thereby greatly shor...

Problems solved by technology

Although this patent can increase the total capacity of the battery pack, it needs to be charged for a long time, and the backup battery pack can only be used after the main battery pack is used up, that is, the backup battery pack can only be replaced when both battery packs are completely exhausted. , and even if the backup battery pack is replaced, the main battery pack still needs to be charged at the charging station, which takes a lot of time, so it cannot be replaced quickly to achieve the purpose of fast battery life
