The invention relates to a PTC heater control method and device, an automobile and a storage medium. Wherein the PTC heater comprises a plurality of heating cores, and the plurality of heating cores are respectively arranged on different control branches. On the basis of the control method, the control method comprises the steps that a heating starting signal is responded, and different control branches are conducted in turn, so that the multiple heating cores work in turn. According to the PTC heater, the structure of the PTC heater is optimized, the multiple heating cores are arranged on the different control branches respectively, the optimized control strategy is combined, power is supplied to the heating cores in the PTC heater in turn, it is guaranteed that only one heating core works at the same time, abnormal sounds generated by the PTC heater can be reduced, and the service life of the PTC heater is prolonged. In addition, the current passing through the PTC heater can be stably changed, and the ripple current generated in the circuit is reduced.

    本申请涉及一种PTC加热器的控制方法、装置、汽车和存储介质。其中,PTC加热器包括多个发热芯,多个发热芯分别设置在不同的控制支路上。基于此,控制方法包括:响应制热启动信号,轮流导通不同的控制支路,以使得多个发热芯轮流工作。本申请对PTC加热器的结构进行优化,将多个发热芯分别设置在不同的控制支路上,并结合优化的控制策略,轮流为PTC加热器中的发热芯供电,保证同一时间只有一个发热芯在工作,不仅可以减小PTC加热器产生的异响,还能够使得通过PTC加热器的电流可以稳定变化,减小电路中产生的纹波电流。
