China Emergency Light Manufacturers introduces the basic working principle of car emergency starting power supply:
1. When the AC power is input, the auto-input and reset (mutual input device) is used to start the car. At the same time, the system controller charges and manages the AC power through the charger. Generally, the capacity of the car charger or home charger of the car's emergency starting power supply is generally 1/10 of the capacity of the product itself, which only provides supplementary functions for the product, and does not have the ability to provide inverter current. Under the system regulation of the controller, the inverter will stop working. The input AC power will supply power to the car or other charging electronic products through the mutual input device (self-input and self-recovery).
2. When the AC power is interrupted or overvoltage, the controller system sends instructions to the mutual input device to switch to the inverter power supply, and the power stored in the battery will be used to supply power to other products.
3. When the input AC voltage is normal, the controller's system will issue a command and the inverter will switch to the shutdown state. At this time, the mutual investment device starts to switch from the inverter to the AC bypass power supply. Provide AC power for charging other products. At the same time, it will also charge the battery pack.
4. The car battery is generally 9V~16V. When the car starts, the engine starts to work. At this time, the car battery is about 14V. When the engine is turned off, the car’s battery is approximately 12V.
