Standard battery pack battery replacement communication method suitable for new energy automobile

Abstract

The invention discloses a standard battery pack battery replacement communication method suitable for a new energy automobile, and belongs to the technical field of new energy automobiles. A battery pack BMS of each standard battery pack establishes communication connection with an intermediate conversion controller through CAN communication; according to the battery replacement communication method, the authentication message sent by each battery pack BMS is analyzed through the intermediate conversion controller, and the identity state information of each battery pack BMS is determined, and according to the battery replacement communication method, after protocols are called for different manufacturers and different vehicle types, interconnection and intercommunication between different vehicle types and different battery packs can be achieved through the intermediate conversion controller; therefore, sharing of the battery packs among the battery replacement vehicle models is realized, maximization of resource utilization is achieved, and benefit sharing and cooperation and win-win of all entities participating in the battery replacement service are further realized.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a standard battery pack replacement communication method suitable for new energy vehicles. Background technique [0002] The application of electric logistics vehicles is becoming more and more extensive, and the application scenarios are becoming more and more abundant. In order to meet the needs of users, most of the models launched by car manufacturers have high power and long battery life. time. [0003] However, due to technical obstacles, the existing battery swapping modes all serve a single model. Due to the large investment in power swapping stations, it is difficult for users to achieve profitability if they do not reach a certain scale. At the same time, the biggest technical obstacle is that the BMS communication protocols are different and cannot be interconnected, which restricts the promotion of shared power swapping technology. [0004] I...
