AI Technical Summary
Existing testing methods for the charging and discharging efficiency of plug-in hybrid vehicle batteries cannot accurately reflect the efficiency during actual vehicle use, and there are differences between independent testing and actual use.
In the laboratory, various real-world operating conditions are simulated. By testing the charging, driving, and charging processes on a plug-in hybrid vehicle, the power consumption and charging amount are recorded. The charging and discharging efficiency under different operating conditions is calculated, and combined with the contribution ratio, the overall efficiency of the power battery is obtained.
The testing method can more accurately reflect the overall efficiency of power batteries under actual use conditions, taking into account the influence of electrical components, and providing a more realistic efficiency assessment.
