What is your understanding of the automobile emergency power supply？
Have you ever encountered a situation where you were ready to go to work in the morning, only to find that the car that was still fine last night could not start, which is probably because the battery of the car was dead or damaged? There is no need to worry when the car is out of power. Today, I will teach you some practical techniques, and after learning it, you can start your car with other people's batteries. You can drive your car to the repair shop without having to pay for the trailer. For drivers with poor hands-on ability, it's better to call for help, because it is a technical job to start a car with jumper cables, and it is necessary to know something about the circuit of the car. Moreover, this work is also dangerous, and it will cause great trouble if the car is burned.
What is automobile emergency starting power supply? Automobile emergency starting power supply is a multifunctional mobile power pack developed for car owners. Its characteristic function is to start the car when the car is out of power or unable to start for other reasons. When you forget to turn off the lights all night, the outdoor temperature is too low in cold weather, the battery is seriously fed, the car is idle for a long time, or the battery is seriously aged, etc., you will be embarrassed that you can't start the car.Up to now, there are two kinds of emergency starting power sources in the market: one is lead-acid battery and the other is lithium polymer. The emergency starting power supply of lead-acid batteries is more traditional, which adopts maintenance-free lead-acid batteries, with large mass and volume, large battery capacity and starting current, and inconvenient to carry. Lithium polymer automobile emergency starting power supply is novel, light in weight and small in size, which can be mastered by one hand. These products are generally not equipped with an air pump, and have functions such as overcharge and shutdown. Compared with lead-acid batteries, they are more practical and have higher cost performance.A key sign to judge whether an emergency start-up power supply is excellent is ignition ability and storage time, and storage time is often the place that old drivers care most about.
When the battery power is insufficient, this method can be used for emergency starting. At present, many kinds of emergency starting power sources for vehicles can be found on the market, and their volume and weight are equivalent to the size of batteries, which is also very convenient to use. The specific operation steps of jump start are as follows.
1. Close the two cars until the jumper cable is enough to connect the positive and negative poles of the two batteries. Attention should be paid to ensure that the two cars are not in contact, and only cables with sufficient bearing capacity and insulating sheath are allowed to be used. If the installation position of the battery supplying power on the vehicle is inconvenient for direct jumper, the battery must be removed with tools.
2. Determine the positive pole (+) and negative pole (-) of the two batteries, and connect the positive pole with the positive pole and the negative pole with the negative pole by cables. Pay attention to the positive and negative poles of the battery, and ensure the reliable connection of cables. Arrange the direction of cable to prevent the cable from scratching with adhesive tape or fan during starting.
Turn off all auxiliary electrical equipment on the vehicle, start the vehicle where the battery providing power is located, and make its engine run for several minutes to ensure sufficient power. Then start the vehicle without electricity in the normal way. After starting, lightly step on the accelerator pedal to make the engine run at 2000r/min for several minutes.
At the end, the newly started car can be kept in the starting state. Put in neutral for 5 minutes, and then put in neutral or other gear for 20 minutes before turning off the engine. This will give enough electricity to the dead battery. If this doesn't work, it is very likely that the battery or generator is broken.
