Air conditioner air volume distribution control method and system under special working condition
By acquiring vehicle and battery status information and optimizing the air conditioning airflow distribution, the problem that electric vehicle air conditioning cannot simultaneously meet battery heating and passenger compartment heating needs under low battery and low temperature conditions is solved. This achieves effective thermal management power distribution under low temperature and low battery conditions, improving the heating effect of the passenger compartment and user experience.

AI Technical Summary
In low battery and low temperature conditions, the air conditioning of electric vehicles cannot simultaneously meet the needs of battery heating and passenger compartment heating. Existing technology has failed to effectively allocate thermal management power, resulting in poor heating effect in the passenger compartment.
By acquiring vehicle status information and battery status information, combined with the SOC and battery temperature change rate, priority is given to ensuring the heating needs of the driver's area, and the air conditioning air volume distribution is adjusted, including adjusting the blower speed and the opening of the air vent damper, and optimizing the thermal management power distribution.
In low temperature and low power conditions, the air conditioning air volume distribution was optimized, the heating effect of the passenger compartment was improved, the user experience was enhanced, the control capability of the air conditioning was expanded, and the charging rate and the heating demand of the passenger compartment were balanced.
