The invention discloses a control method of a liquid heater and the liquid heater. The control method comprises the steps that the heating requirement of a whole vehicle heat management controller is received; determining the output power of the liquid heater according to the heating requirement; and the corresponding number of IGBT switches are controlled to be started according to the output power, so that the cooling liquid is heated. In the application, the liquid heater outputs the fixed power corresponding to the heating requirement, so that the influence caused by current fluctuation is avoided.

    本申请公开了一种液体加热器的控制方法以及液体加热器,控制方法包括:接收整车热管理控制器的加热需求;依据加热需求确定液体加热器的输出功率;依据输出功率控制对应数量的IGBT开关启动,从而对冷却液进行加热。本申请中,液体加热器输出与加热需求对应的固定功率,避免电流波动带来的影响。
