Drive control apparatus for fluid heater and control method thereof

The present invention relates to a drive control apparatus for a fluid heater for battery temperature control and a control method thereof, and more particularly, to such a drive control apparatus for a fluid heater and a control method thereof, the connection configuration between the power supply unit, the first heating element, and the second heating element is set differently according to the value of the voltage supplied from the power supply unit so as to ensure that a peak current limit, a maximum heater heat value limit, and a maximum allowable power density are satisfied. And therefore, the application range of the voltage can be maximized and the stability of the heater can be satisfied at the same time. 本发明涉及用于电池温度控制的用于流体加热器的驱动控制设备及其控制方法，并且更具体地，涉及这样的用于流体加热器的驱动控制设备及其控制方法，其中，根据从电源单元供应的电压的值不同地设定电源单元、第一加热元件和第二加热元件之间的连接配置，以便确保满足峰值电流极限、最大加热器热值极限和最大允许功率密度，并且因此能够最大化电压的适用范围并且能够同时满足加热器稳定性。
