Battery chemical energy is converted into electrical energy: The lead-acid battery is composed of positive and negative plates and sulfuric acid electrolyte. During the charging process, electrical energy is converted into chemical energy and stored in the battery; when the car is ignited, the battery converts chemical energy into electrical energy through chemical reactions and releases it to provide power support for the car to start.
·Meet the power demand for car starting: When the car starts, the starter needs a large current to drive the engine. The lead-acid batteries of these two portable power stations can output large currents in a short time. Taking a common car as an example, a current of several hundred amperes is generally required for starting. Although 200W and 500W refer to the power of the power supply, at a voltage of 12V, the battery capacity of 30Ah and 50Ah can ensure that sufficient large current is provided in a short time to meet the working requirements of the car starter and enable the engine to start smoothly.
·Energy transmission through circuit control: The portable power station has a complex circuit control system inside, including a battery management system, a protection circuit, etc. The battery management system monitors the battery status in real time, such as voltage, current, and temperature, to prevent overcharging, overdischarging, overcurrent, and short circuit, and protect the battery and connected devices. When connected to the car battery, press the start button, and the control circuit will transfer the battery's power to the car's electrical system. At the same time, the protection circuit will quickly cut off the circuit in the event of abnormal conditions such as reverse connection, overtemperature, and short circuit to ensure safe use.
·Correctly connect to form a closed loop: Use a connecting wire with a clip to correctly connect the positive and negative poles of the portable power station to the positive and negative poles of the car battery to form a closed circuit, so that the energy in the energy storage power supply can be transferred to the car's electrical system to provide power for starting the car.
The starting current requirements of different models may be different. When using a portable power station to ignite a car, it is necessary to ensure that the specifications of the power station can meet the car's starting requirements to avoid damage to the equipment or failure to start the car normally.
