The invention provides a vehicle-mounted air purifier starting instant current overload protection method which comprises the steps that S1, a vehicle-mounted fan is started, the current value of the vehicle-mounted fan is detected, and after the current value of the vehicle-mounted fan is stable within a certain time, the output voltage of a DC-DC module is set to be the highest gear voltage value; s2, starting the ion generator, detecting the current value of the ion generator, and recording the current value if the detection fluctuation time is reached and the current value is stable during detection; s3, the PWM value for adjusting the rotating speed gear is calculated by adopting the set rated power and the current value of the ion generator; s4, the rotating speed of the vehicle-mounted fan is gradually increased according to the PWM value, and if the current value of the vehicle-mounted fan reaches a set current threshold value and is stabilized for a period of time, starting is completed; according to the method, the rotating speed of the fan is limited, then the ion generator is driven to be started, starting is completed in the mode that the actual working current of the ion generator is detected to adjust the rotating speed gear of the vehicle-mounted fan, and the problems of voltage drop and poor stability caused in the starting process of the fan and the ion generator are effectively solved.
本发明提供了一种车载空气净化器启动瞬间电流过载保护方法,其包括:S1:启动车载风扇,检测车载风扇的电流值,车载风扇电流值在一定时间内稳定后,将DC‑DC模块的输出电压设置为最高档位电压值;S2:启动离子发生器,检测离子发生器的电流值,检测时若检测波动时间到达、电流值稳定,则记录电流值;S3:采用设定的额定功率和离子发生器电流值,计算出调节转速档位的PWM值;S4:根据PWM值逐步提升车载风扇转速,若车载风扇电流值到达设定电流阈值且稳定一段时间后,则启动完成;本发明中通过限制风扇的转速,再驱动离子发生器启动,通过检测离子发生器的实际工作电流来调节车载风扇转速档位的方式完成启动,有效解决二者启动过程中导致的电压跌落、稳定性差的问题。
