An electric car repair shop maintenance staff replaces the battery for the customer

It is very common to replace and install batteries.

Yesterday, the reporter visited a number of electric vehicle repair shops, learned that the general replacement of high-power batteries are young people, and found that the installation of electric motors, batteries for electric vehicles is very common. The car is too slow, and the battery is running fast. Some people also go to replace the battery because of the long life of the electric vehicle and the aging of the battery.

The modified battery can only be used for battery life and cannot increase the speed.

"Refit is actually very simple, that is, the battery with the original voltage of 48 volts 20 amps, and then a group of batteries, the voltage and current of the electric car will increase." An electric car store maintenance staff said, but install the battery and Can not increase the speed of the car, can only improve the cruising range of the electric car.

"The speed of the car is related to the motor. It can be improved by changing the speed of the motor." The maintenance personnel said that even if the motor is replaced, the electric car can only reach the speed of the electric motor and will not exceed 60 km/h. "In fact, as long as the battery power is enough, there is no need to modify the speed."

After installing the battery, will it bring the risk of burning? "After the battery is replaced, the connected line should also be replaced.

Need to go to a professional agency for identification

Difficult to supervise

According to the "General Technical Standard for Electric Bicycles", the maximum speed of electric vehicles is not more than 20 kilometers, and the standard voltage of batteries should be no more than 36 volts. However, according to this standard, the above-mentioned modified electric vehicle is obviously a super-standard electric vehicle.

Then, how will these super-standard electric vehicles be supervised? In this regard, a staff member of the Luoyang City Administration for Industry and Commerce has told the reporter that the Industry and Commerce Bureau is in charge of the electric vehicle circulation field, and the electric vehicles are generally modified after the sale.

“Few people report or complain about the private modification of electric vehicles, so it is difficult to supervise.” The staff said, in addition, whether the electric vehicle exceeds the standard requires identification by a professional organization, which makes the supervision more difficult. At present, Luoyang City Industrial and Commercial Bureau can only increase management in the quality and sales of electric vehicles.

Swimming Pool Heat Pump

Compared to other heating methods, inverter pool heat pumps are generally more energy-efficient and cost-effective in the long run with advanced technology. They can also operate in a wider range of temperatures and can heat water more gradually and evenly, which can lead to a more comfortable swimming experience. UWO offers a wide range of high-efficient inverter pool heat pumps for above ground pools.
