Description

technical field [0001] The invention relates to a performance testing platform and a testing method of a battery management system, belonging to the field of system testing. Background technique [0002] Due to problems such as resource consumption and environmental pollution, many disadvantages of traditional vehicles have emerged during the use process. As a new energy vehicle, electric vehicles have attracted widespread attention due to their extensive energy sources and low environmental pollution. The power battery pack is a key component of electric vehicles. When the power battery pack encounters overcharging, over-discharging, etc., the service life of the battery pack will be shortened and safety problems may occur, endangering the vehicle. and occupant safety. In order to protect the power battery pack and prevent safety accidents, people add a battery management system to the power battery pack to monitor and manage the state of the battery pack. At present, man...
