Problems solved by technology
[0002] At present, the static battery detection system can set the actions required for battery performance testing through flexible programming, and can conduct long-term battery performance testing, including SOC (state of charge) estimation, etc., and automatically record Experimental data, but the static system lacks dynamic simulation of battery operating conditions, and the realization function is limited
[0003] The dynamic battery detection system is installed on the electric vehicle, which can monitor the battery state during the actual operation of the battery. Its functions include SOC estimation, balanced charging, fault alarm and communication, etc., all of which are aimed at the needs of electric vehicles. Therefore, the The collected data can reflect the actual battery operating conditions during the operation of the vehicle. The disadvantage is that because the operation of electric vehicles relies on manual work, it is difficult to accurately control the actions required for battery testing when quantitative requirements are placed on battery performance testing.
