AI Technical Summary
Under extreme cold conditions, existing technologies cannot dynamically control the intermittent start-stop duty cycle of the heating device, resulting in serious waste of heating power consumption, and repeated heating fluctuations may cause lithium plating and aging problems in the battery.
By extracting the timing characteristics of surplus power during the charging process, the correlation characteristics between temperature and polarization state, and the coupling characteristics between energy storage capacity and power supply demand on cloudy and rainy days, the intervention power and duty cycle of the heating device are dynamically adjusted. Combined with polarization safety domain and lithium plating risk correction, a start-stop pulse sequence is generated, and the ramp-up and ramp-down rates of the duty cycle are adjusted during the pulse start and end phases.
It achieves the minimum self-consumption of heating power, avoids lithium plating and aging of batteries caused by heating fluctuations, and ensures the battery's endurance during continuous cloudy and rainy days.
