Why is the electric car battery so hot when charging?

The electric vehicle heats up during charging. Possible causes are:

1. Battery problems: Battery aging, increased internal resistance, electrolyte drying, internal short circuits, etc. can cause heating. These problems can be solved by adding water, desulfurization and depolarization. If the battery heats up due to short-circuiting, it is recommended to replace the battery with a new one.

2. Charger problem: Ordinary chargers on the market cannot detect the internal resistance of the battery in time. Even if they can detect it, they cannot make timely charging adjustments or provide the best charging plan. These are the reasons why the battery heats up during the charging process.

Where is the electric vehicle certificate number?

The vehicle certificate number is under the barcode on the upper right of the inner page of the large green cover "Registration Certificate". The vehicle certificate is a legal document printed by the motor vehicle manufacturer and sent with the vehicle to prove the vehicle's qualification. In layman's terms, the vehicle certificate is the "identity card" of the vehicle, and a new car without a certificate is equivalent to a "black account". At the same time, the certificate is also a valid certificate for vehicle registration and insurance purchase. Without a certificate, the vehicle cannot be registered normally, and some insurance types cannot take effect.

How to register an electric vehicle online

Electric vehicles purchased online need to ask the store to issue a purchase invoice, so that car owners can take the purchase invoice, ID card, and vehicle certificate to the relevant department for registration. If the electric vehicle purchased online does not meet the standards, it cannot be registered, so friends should pay attention.

As the number of electric vehicles increases, some bad phenomena have emerged. Many friends do not obey traffic rules when riding electric vehicles. Therefore, in order to uniformly manage these electric vehicles, the relevant departments require electric vehicles to be licensed.

It is recommended that friends obey traffic rules and wear helmets when riding electric bikes, which will help improve the safety of riding. When riding an electric bike, do not occupy the motor vehicle lane, which may cause traffic jams and may also cause traffic accidents. When riding an electric bike, obey traffic lights. When using an electric bike, you must take anti-theft measures. There are many criminals who will steal the batteries of electric bikes for profit, so riders must pay attention. There are generally two types of batteries used in electric bikes, one is lead-acid batteries and the other is lithium batteries. The price of lithium batteries is relatively expensive.
