What Voltage Should The Battery Of Electric Vehicle Choose

What voltage should be selected for electric vehicle battery?

The voltage rise will bring two biggest problems: safety and difficulty in the design of electrical components. However, DC is more dangerous than AC with the same voltage. Different countries have different laws and regulations. Generally, DC power less than or equal to 36V or 48V is considered as safe voltage, and over 60V voltage can cause harm to human body. In EU electrical regulations, products above 48V require additional electrical safety certification. Low pressure is recommended.

Precautions for battery replacement of electric vehicle:

1. In the process of electric vehicle license plate or battery replacement, some illegal vendors in order to save costs, steal the battery or charger, so that consumer products have potential safety risks, which will have to go to the regular manufacturers with credibility to replace and purchase.

Check whether the electric vehicle battery product marks are complete, including the manufacturer name, product specification and model, manufacturing date and trademark; check whether the internal and external marks are consistent, especially whether the product body has eye-catching identification and production date. Appearance of electric vehicle battery. Check whether there is deformation, crack, scratch and leakage trace. The battery terminal should be clean and free of rust, and the mark should be clear.

2. The battery model matches the electric vehicle,

It is feasible to replace the lead-acid battery and lithium battery with the same capacity and voltage. However, it is necessary to consider whether the size of the battery can still be installed in the original position, and whether it protrudes or is squeezed, because extrusion and damp will damage the internal part of the battery and cause short circuit. In addition, the voltage should be matched with the battery motor.

3. Battery brand model mismatch

The brand model registered on the electric vehicle certificate does not match the brand and model of the battery used in the electric vehicle. There is the possibility of replacing the original battery with the inferior one or using the renovated battery instead of the original battery, which is easy to cause spontaneous combustion and other hidden dangers.

4. Chargers that match the battery type must be used

The capacity and voltage of lead-acid battery and lithium battery are the same, so the charger should not be used indiscriminately, because the charging voltage and current of the two batteries are not equal in each stage. Therefore, choose and purchase the battery matching, with automatic control of intelligent charger. When the lead-acid battery is charged, the charger voltage is high. The lithium battery has high technical requirements, so when charging, the charger adopts constant current and constant voltage charging. Lead acid charging lithium battery will lead to overcharge and explosion risk.

5. When buying electric vehicles, you must check whether they are in the catalogue of electric bicycles. Do not buy illegally assembled electric vehicles for cheap prices.

6. Do not illegally refit electric vehicles
