Problems solved by technology

[0003] 1. Existing charging pile test equipment, when doing communication protocol BMS test, only protocol analysis is done. When the charging pile is tested on-site at the charging station and there is no electric vehicle, only the load with BMS protocol can be used. test
[0004] 2. It is impossible for existing electric vehicles to adapt to all types of charging piles when doing charging protocol testing. In order to fully test the adaptability of electric vehicles to charging piles, electric vehicle manufacturers can only purchase various types of charging piles for testing and comparison experiments
[0005] 3. In the electric vehicle 4S shop, when repairing electric vehicles, they do not have the conditions to install various types of charging piles

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging testing, in particular to a charging pile tester with a bidirectional simulation BMS protocol and a testing method thereof. Background technique [0002] With the promotion and application of new energy electric vehicles, the demand for BMS (Battery Management System) also appears. The battery management system needs to be bidirectionally matched with electric vehicles and charging piles to work properly. The current testing of the battery management system has the following problems: [0003] 1. Existing charging pile test equipment, when doing communication protocol BMS test, only protocol analysis is done. When the charging pile is tested on-site at the charging station and there is no electric vehicle, only the load with BMS protocol can be used. test. [0004] 2. It is impossible for existing electric vehicles to adapt to all types of charging piles when performing chargi...
