How to make your own car jump start power tutorial

Buy a three-string lithium battery pack or four-string lithium iron phosphate battery pack with more than 10Ah (preferably more than 20Ah).

group, the protection board uses 100A, the positive and negative outputs are connected to the power clamp, and the faulty car is connected to the starter car.

Understand, use the ordinary protection board to connect the ordinary equipment and charging (start the car, without the protection board), start the positive and negative poles of the power clamp without passing through the protection plate, directly from the positive and negative poles of the battery pack to connect a 60A fuse to lead out, so that the operation of the starting car, pay attention to the battery capacity.

Not less than half.

Good professional knowledge is a must.

1. Generally speaking, the instantaneous current of electrical appliances when starting in BAI will be much larger than the normal working current, and the instantaneous current of the car will reach more than 200 amperes when starting, and the general power bank can not withstand such a large current, and there is no interface to adapt to the wire, and this kind of car emergency starting power supply can support the maximum current of 200A-400A.

2. After dismantling this ultra-high current power bank, the equipment inside is different from the conventional power bank, and it is not a 18650 power plant, but a larger lithium battery, which is professionally called: high-rate power polymer cell. The wire of the dedicated interface for starting the car is much thicker than other lines, and it is the basis for bearing a large current, which is also an important difference from ordinary power banks.

3. Its use is very simple, basically the same as the daily use of the power bank, but the output is changed to a battery clamp, and the positive and negative poles of the battery corresponding to the battery clamp are clamped on the terminal post of the battery when in use.

Press the switch on the emergency start power supply of the car to make the power supply in the state of on, and the state at this time is equivalent to the state of the traditional power method, and the next step is to start the rescued vehicle.

1. Turn off high-consumption equipment such as navigation and air conditioning, then clean up the dust of the car's power connector, and start the power display of more than 3 bars.

2. Use the red clip on the emergency starting power supply to clamp the positive pole of the car power supply; A black clip clips to the negative pole of the car's power supply.

Start the car within seconds, immediately unplug the battery clamp, and remove the emergency starting power supply. It should be noted that if the car is started once, the product indicator lights are all turned off, and the illusion of no electricity occurs, because the output current of some cars is too large, the emergency starting power supply starts the internal protection system, and the emergency power supply can be activated by charging it for 3 seconds.

4. After starting, charge the battery at 1500 rpm, after 20 minutes, it can be used for starting once, and after 30 minutes, it can be used for starting once the next day.

The car emergency starter power supply is a multi-functional mobile power pack, which is a bit similar to our mobile phone power bank. When the car loses power, it is very convenient to use this power supply in an emergency. It can be said to be one of the must-have items for outdoor travel.

Since the car emergency starting power supply is so easy to use, how to use it correctly? What are the precautions?

The specific use method of automobile emergency starting power supply.

1.Start by finding the location of your car's battery, and then connect the emergency start power harness to your car's battery. Generally, the positive pole of the battery is connected with a red clip, and the negative pole of the battery is clamped with a black clip.

2.After clamping, turn on the start switch of the car emergency starting power supply, and then insert the connector of the battery clamp into the interface of the automobile emergency starting power supply. It is important to make sure that the emergency power is in the "off" state and then turn the emergency start power switch to the "on" state.

3.After doing these jobs, check again whether the anode and cathode are connected incorrectly and whether the clamp is clamped. Finally, you can get in the car and start the vehicle. It is best to unplug the emergency power supply within 30 seconds after the vehicle is started to avoid heating.

and other reasons.

Precautions for the use of automobile emergency starting power supply.

1.For some traditional lead-acid batteries.

The current is generally relatively large, so you must take protective measures when using it, otherwise it is easy to hurt yourself. In addition, do not disassemble the emergency starting power supply of the car without permission to avoid accidents or damage to the power supply. There are also some lithium polymer batteries.

The power is relatively low, but pay attention to the voltage when initiating the ignition in an emergency. If the voltage is insufficient, it will be difficult to start successfully, and the power in the emergency power supply will be wasted.

2.When the car emergency power supply is not in use, it must be placed out of the reach of children to avoid children from touching or using the car emergency starting power supply. The best place to store it is to choose a cool, dry place away from direct sunlight.

3.When not in use, the emergency power supply should be fully charged. Although the emergency power supply can provide starting power for the car, it belongs to the mobile power supply after all.

If it is not suitable for storage for too long, the battery will automatically drop. Therefore, most of the time when not in use, it needs to be recharged from time to time to keep the power supply fully charged, thus extending the life of the emergency power supply. Generally speaking, it can only be charged once in three months.

In addition, when charging, you need to use a specially equipped charger.

4.Pay attention to the frequency of use of the emergency power supply. Because the power in the emergency power supply is also limited, sometimes after the car battery is powered off, the emergency power supply may not start successfully at one time, and even if the start fails, it will consume power.

Generally speaking, a lithium polymer power supply can only be used 5-10 times when fully charged, while a lead-acid power supply can only be used due to its large size and current intensity.

Large, can only be used about 30 times. If it fails to start several times, it is best to fully check whether the vehicle cannot be started due to the power supply.

1.There are several ways to use the emergency starting power supply of the car: first turn off the high-power consumption equipment such as navigation and air conditioning, and then clean the dust of the car power connector, and the starting power supply will display more than 3 grids of power supply.

2.Clip the red clip on the emergency start power supply to the positive end of the car's power supply, and the black clip to the negative end of the power supply.

Start the car in seconds and immediately unplug the battery clamp and emergency start power. It should be noted that if there is a starter, the lights of this product will all go out, and there will be the illusion of no power. Because the output current of some cars is too large, the emergency starting power supply starts the internal protection system, and the emergency power supply can be activated for 3 seconds.

4.After the vehicle is started, it will be charged at 1500 yuan. It can be started once after 20 minutes and the next day after 30 minutes.
