Speaking of the emergency starting power, its main work is to start the ignition power equipment for a short time to the car when the car battery fails to start due to power failure or necrosis.
The working principle system of automobile emergency starting power is mainly inverter function, which is also the core function of the product. It includes discharging and charging, power storage, etc. Easy to carry and operate is the original intention of automobile emergency design. The shell made of PVC and ABS is adopted, and the polymer electric core of high magnification aeromodel is adopted. Digital LED power display. The vehicle emergency starting power can be charged by car charging and home charging. The product is equipped with automatic reverse charging and overcharging functions. It can protect the circuit of starting power. Constant light, explosion flash, SOS emergency light can be turned on only by lightly pressing the white button.
Basic working principle of vehicle emergency starting power:
1. When the alternating current is input, it is used to start the car through the automatic switching and automatic recovery (mutual switching device). At the same time, the system controller will charge the alternating current through the charger and manage it. Generally, the capacity of the car or home charging of the emergency starting power is 1 / 10 of the product's own capacity, which only provides supplementary functions for the product, but does not provide inverter current. Under the control of the controller, the inverter will stop working. The input AC power will be supplied to the car or other charged electronic products through the mutual switching device (self switching and self resetting).
2. In case of interruption or overpressure of alternating current, the controller system will send instructions to the mutual switch device and switch to the inverter for power, and then the power stored in the battery will be used to power other products.
3. When the input AC voltage is normal, the system of the controller will issue a command, and the inverter will switch to the off state. At this time, switch on the mutual switch device to start the conversion from the inverter to the AC bypass power. To charge other products and provide alternating current. It also charges 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 off, the battery of the car is about 12V.
