Problems solved by technology

Some manufacturers use the battery swap method to reduce the cost of the first car purchase, and at the same time, it can also solve the problem of mileage anxiety. However, due to the small market capacity of a single battery swap model, the operating cost of the battery swap operator is high, which directly affects the promotion of the battery swap model.

Embodiment 1

[0062] In this embodiment, a battery exchange system for sharing standard battery packs 7 for electric logistics vehicles is specifically disclosed, aiming to solve the problem that the electric logistics vehicles cannot be flexibly combined according to the weight of the goods and the distance of the transportation distance during the application process of the electric logistics vehicles. A variety of power sources can be generated, so that the same vehicle cannot meet multiple application scenarios.

[0063] In order to solve the current problems and realize corresponding functions, such as Figure 1-Figure 4 As shown, the power exchange system mainly includes: a standard battery pack 7, an installation frame 14, and an intermediate conversion controller 15 (ie: MCCU), wherein the number of the standard battery pack 7 has multiple backups to meet different application requirements. Select an appropriate number of standard battery packs 7, the standard battery packs 7 are eq...

Embodiment 2

[0079] Due to the different battery BMS communication protocols of various manufacturers and models, it is impossible to form a universally adapted shared battery swap system in the market, resulting in a huge waste of resources and a bottleneck in the promotion of battery swap logistics vehicles. In this embodiment, a battery exchange method for sharing the standard battery pack 7 of the electric logistics vehicle is specifically provided. In application, the CAN network of the whole vehicle is used as the communication medium, and the CAN network is connected with VCU, IP, MCCU, T-BOX, MCU and IPU, and data interaction is performed under the CAN network, such as Figure 5-Figure 8 As shown, the battery replacement method includes:

[0080]S1: Select a corresponding number of standard battery packs 7 according to different application scenarios and assemble them in place on the installation frame 14, and the battery pack BMS17 of each standard battery pack 7 establishes a com...

Abstract

The invention discloses an electric logistics vehicle shared standard battery pack battery replacing system and a battery replacing method, and belongs to the technical field of new energy automobiles, the battery replacing method can directly convert communication interaction between BMS of each manufacturer and vehicle controllers of different vehicles through a battery intermediate conversion controller, the problem that interconnection and intercommunication cannot be achieved is thoroughly solved. The problems that due to the fact that battery BMS communication protocols of various vehicle types of various manufacturers are different, common adaptation and shared battery replacement cannot be formed in the market, and great waste of resources is caused are thoroughly solved; meanwhile, the installation structure of the standard battery pack is optimally designed in the battery replacing system, so that the same vehicle can flexibly configure different numbers of standard battery packs in different scenes, various actual use scenes of users are met, the battery replacing vehicle type can utilize social resources to the maximum extent, and the win-win situation of cooperation of all participants is formed.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a battery replacement system and method for sharing standard battery packs of electric logistics vehicles. Background technique [0002] In recent years, the state has given many preferential policies to new energy vehicles, which has greatly promoted the development of new energy vehicles. But in actual use, there are still many unsatisfactory places. [0003] Electric logistics vehicles play the main role in the intra-city distribution business, with rich application scenarios. The car manufacturers of new energy vehicles tend to develop models with large battery capacity and long battery life, in order to meet more application scenarios. But it brings new problems, the cost of the whole vehicle remains high, and the power in some scenarios is excessively redundant. [0004] In practical applications, there is a lack of a battery exchange system for e...
