The basic working principle of the car jump starter:
1. When the AC is input, it can be automatically restored to start the vehicle through automatic switching (mutual switching device). At the same time, the system controller will charge and manage the AC through the charger. In general, the vehicle charging or household charging capacity of the vehicle emergency start power supply is generally 1/10 of the product’s own capacity, which only provides supplementary functions for the product and does not provide inverter current. Under the system regulation of the controller, the inverter will stop working. The input AC will supply power to the car or other live electronics through an inter-switching device (auto-switching and auto-recovery).
2. When the AC power supply is interrupted or overvoltage, the controller system sends a command to the mutual switching device and converts it to the inverter to supply power, and the inverter will use the power saved by the battery to supply power to other products.
3. When the input AC voltage is normal, the controller system will send a command, and the inverter will switch to the shutdown state. At this time, the switchover device starts to switch from the inverter to the AC bypass power supply. Charge other products and provide AC power. It also charges the battery pack.
Car batteries are generally 9V~16V. When the car is started, the engine starts to work. At this point, the car battery is about 14V. The car’s battery is around 12V when the engine is off.
