Speaking of car jump starter, its main job is to start the ignition power supply device to the car for a short time when the car battery is dead or dead and cannot be started. In recent years, most cars have frequently experienced battery loss. It is precisely because of this that the domestic automotive emergency power supply industry is booming. Next, Our company will take you to understand the working principle of the power supply. The working principle of the automobile emergency starting power supply system is mainly the inverter function, which is also the core function of the product. It includes discharge and storage, etc.
Easy to carry and easy to operate is the original intention of the car's emergency design. The shell is made of PVC and ABS materials, and the high-rate HM polymer batteries are used. Digital LED power display. The car emergency starter can be charged by car charger and home charger. The product is equipped with automatic reverse charging and overcharging functions. It protects the circuit of starting the power supply. Constant light, flashing, SOS emergency light can be turned on by simply pressing the white button.
The basic working principle of the multi-function car jump starters:
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 issues instructions to the mutual input device to switch to 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.
