The safety guarantee of electric tricycles starts from the time of purchase. It can be seen that to ensure the safety in the use of electric tricycles, consumers should pay attention to it when purchasing. The protection systems of formal manufacturers are relatively complete, and the circuit materials and interfaces of various components are relatively formal. Consumers should not be greedy for bargains. They must choose electric tricycle models from formal manufacturers or well-known brands.

In addition, consumers should also pay attention to the standard operation of electric tricycles and batteries in the process of use to prevent overcharge and overcharge. After the battery of electric tricycle is heated, cooling measures shall be taken, and the battery can be charged only when the battery temperature of electric tricycle returns to normal. The installation position of electric tricycle battery shall ensure good heat dissipation as far as possible. In case of overheating, stop charging, and check the charger and electric tricycle battery. The charging time should be shortened when the battery discharge depth of the electric tricycle is shallow or the ambient temperature is high

The motor vehicle must be equipped with at least one permanent product label. The fixing method, location, size and type of the label shall comply with the provisions of GB/T 18411. The specific location shall be specified in the product manual. For refitted vehicles, the product label of the original chassis shall not be removed.

All motor vehicles shall be marked with the manufacturer's license plate, vehicle model, manufacturing date, manufacturer's name and place of origin on the product label. See Table 1 for other items that shall be marked on the product labels of various motor vehicles. The content indicated on the product label shall be standard, clear, durable and easy to identify, and the project name shall be in Chinese

Water leakage inspection

During engine operation and shutdown, water tank, water pump, cylinder block, cylinder head, heating device and all connecting parts shall be free of obvious water leakage.

Oil leakage inspection

The continuous driving distance of the motor vehicles shall not be less than 10 km. After stopping for 5 minutes, observe that there is no obvious oil leakage

4.13 Indication error of speedometer (except for motor vehicles with maximum design speed less than or equal to 40km/h)

The relationship between the indicated vehicles speed V1 (unit: km/h) of the speedometer and the actual vehicle speed V2 (unit: km/h) shall conform to the following formula:

0≤ V1-V2≤ V2/10 +4
