Disc-type power battery module for electric vehicle

Abstract

The invention provides a disc-type power battery module for an electric vehicle. The disc-type power battery module comprises a disc-type frame, single battery modules and a lock buckle; the disc-typeframe is of a cylinder disc structure, and is divided into a plurality of equal sub-spaces, the unit battery modules are disposed in the sub-spaces, and the end of a partition plate of the disc-typeframe is provided with the lock buckle. The disc-type module is divided into six separate battery modules, each of which can be separately disassembled; when the module is mounted on the electric vehicle, as the module can be rotated, the battery module can be replaced at any time by forming a battery exchange port in the side of the electric vehicle, the operation is simple and convenient, thereis no need for large-scale power-changing equipment and a large number of manpower, the owner can replace the full-cell battery module by himself, if the owner needs to travel for a long time and thelocation information of a battery exchange station is unknown, he can prepare additional battery modules in advance according to the journey, when the power needs to be replenished, the single batterymodules can be replaced by himself, which is simple and convenient, and solves the problem of insufficient battery life.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a power battery module of a wheel-type electric vehicle. Background technique [0002] With the intensification of the global energy crisis, oil resources are facing depletion, and the air pollution and global warming caused by the consumption of fossil fuels have seriously affected human life. People's favor, the future direction of automobile development is also gradually moving closer to electrification. As the core power part of electric vehicles, power batteries limit the development of electric vehicles to a certain extent due to high technical requirements. When the power is exhausted, there are two ways for electric vehicles to replenish energy, one is charging, and the other is battery replacement (replacing the battery module). [0003] The charging method takes a long time and cannot satisfy the instant power replenishment of electric vehicles d...

AI Technical Summary

Problems solved by technology

[0003] The charging method takes a long time and cannot satisfy the instant power replenishment of electric vehicles during driving intervals. Moreover, charging piles at charging stations are limited. Compared with traditional fuel vehicles, the charging efficiency of electric vehicles is far lower than the refueling efficiency of fuel vehicles, which is also one of the main problems restricting the promotion of electric vehicles in the market

The battery replacement method takes less time and can immediately meet the customer's demand for power. However, since the battery replacement operation requires professional equipment and personnel to operate, the owner needs to go to the power station for replacement, and the staff will replace the entire battery module. Currently, , the penetration rate of battery replacement stations is very low, and at the same time, the design of battery modules of different models is not uniform, which brings a lot of trouble to battery replacement. In addition, many car owners run out of power on the way when they travel long distances, and there is no charging nearby. station and changing the power station, resulting in helplessness and can only call a tow truck, which brought a lot of trouble and added extra work to many departments
