There are three general solutions to the problem of a car battery that won't turn on: start with a cart, start with a battery, and charge with a charger.
1. Trolley start:
Trolley start is only suitable for manual transmission cars, not for automatic transmission cars. , starting a stroller with a manual transmission relies on the principle that there is some battery left in the battery. You need to engage first gear, press the clutch, turn the car key to the start position, then push the cart forcefully. vehicle speed increases, quickly release the clutch. Due to inertia, the motor will fire successfully.
2. Start by powering up:
Prepare two battery lines and a vehicle with sufficient battery power. Find the positive and negative batteries of bothvehicles. . pole, connect the positive pole of the two car batteries with one battery wire, then use another wire to connect the negative pole of the two car batteries.
Be careful not to reverse the positive and negative poles. After assembling the battery cables, turn on the ignition and start the vehicle. Once the vehicle has been successfully started, carefully remove the battery cables one by one. do not touch the metal body or other parts.
3. Charger charging:
If the car battery is seriously exhausted and cannot be started electrically, the battery can only be charged with a charger. The charging method is constant voltage and constant current charging. Generally, car owners do not have a charger, so it is recommended to take it to a professional repair shop.
If the battery is used for a long timeiodine, it is recommended that you consider replacing it. Battery life is basically 2-4 years. If used for a long time, the phenomenon of power loss will occur. more and more frequent.
Note:
Shell protection, in order to prevent air from entering, lithium batteries are packaged in airtight containers and are generally equipped with a stainless steel shell. and aluminum alloy shell.
For example, Tesla's electric cars even use titanium alloy protective plates to prevent damage to the battery box when using the car, especially in road accidents. the road.
The diaphragm blocking protection not only prevents damage from external forces, but also prevents damage from inside the battery. Usually, in order to avoid that the electrodes positive and negative electrodes of the battery are in direct contact and cause a short circuit, there is a separator inside the battery, which on the one hand separates the positive and negative electrodes, and on the other hand leaves pass the charged ions.
However, in lithium batteries, the separator also performs another protective function. When the battery temperature is too high, the separator gap automatically closes, preventing the lithium ions from crossing over, thus ending the entire battery reaction. This avoids the problem of battery electrolyte vaporizing and generating high pressure due to excessive temperature, thereby damaging the battery sealing structure.
