Auto emergency start power working principle

Speaking of car emergency power supply, its main job is that when the car battery dead or dead can not start, you can start the car ignition power equipment for a short time. In recent years, most of the cars will have a regular battery loss of electricity, precisely because of this, the domestic auto start emergency power industry to flourish. Now I will take you to learn about the working principle of starting the power. Automotive emergency start power working principle The system is mainly inverter function, but also the core functions of the product. It includes charging, storage and so on.

    Easy to carry, easy to operate is the original intention of the car emergency design, the use of PVC material and ABS shell, high-rate model polymer batteries. Digital LED power display. Auto emergency start power through the car charger and charger, the product is equipped with automatic reverse charge, overcharge function. To start the power supply circuit to play a protective role. Constant light, flashing, SOS emergency light only need to tap the white button to open.

   Multi-purpose car emergency start power basic working principle:

    1. During AC input, the car is started by self-commutating (inter-switching device), while the system controller charges the AC power through the charger and manages it. Usually car emergency start power car charger or charger capacity is generally the product itself, the capacity of 1/10, only to provide additional product features, and do not have to provide the inverter 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 product through the crossbar device (self-turning on).

    2. When there is an interruption or overvoltage in the AC power, the controller system issues a command to the mutual-input device and shuts it down to power the inverter and then uses the stored power of the battery to power other products.

        3. When the input AC voltage is normal, the controller system will issue a command, the inverter will cut off to the state. At this point, the voter crossover unit initiates the conversion from the inverter to the AC bypass supply. Charge other products to provide AC power. At the same time it will also charge the battery pack.

 4 car battery is generally 9V ~ 16V, the car starts, the engine began to work, then the car battery is about 14V. Turn off the car's battery is about 12V.
