6.1 Structural inspection

6.1.1 Sharp edges

Use visual inspection and finger touch to check whether the rider's body can touch the electric scooter.

6.1.3 Active clearance

Use a go gauge to measure the active clearance of the electric scooter.

6.1.4 Internal wiring

Use visual methods to check the internal wiring of the electric scooter.

6.2 Performance test

6.2.1 Performance test conditions

6.2.1.4 Test vehicle

The test vehicle is a fully assembled electric scooter; and the battery is fully charged according to the method described by the manufacturer, The battery capacity during the test is no less than 90% of its rated capacity.

6.2.2 Maximum speed

The driver (6.2.1.3) drives the test vehicle to accelerate from rest, keeping the speed knob at the maximum opening, so that the driving speed reaches the maximum speed and remains unchanged; passes through the 5m test section; and records the speed value of the test section.

The test is repeated twice and the average value is taken.

6.2.4 Braking performance

6.2.4.1 Braking structure

The braking system of the test vehicle is visually inspected.

6.3 Electrical safety testing

6.3.2 Short circuit protection

Check whether the battery charging circuit and battery output circuit of the test vehicle are equipped with protective devices such as fuses according to the circuit diagram. Check the charging circuit, battery output circuit, or circuit board, if necessary.

6.3.5 Charging lock

Use the adapter charger to charge the test vehicle battery when it is powered off. During the battery charging process, turn on the power switch and check the operation of the motor of the test vehicle.

6.3.6 Braking power off

Lift the driving wheel of the test vehicle off the ground; connect a DC ammeter in series to the battery output terminal; turn on the power; and record the current value (standby current) when there is no torque output on the driving wheel.

6.3.7 Charging port protection

Check whether the charging port of the test vehicle and the charger output interface are the only connection methods; if not, try to reversely connect the charger to the charging port of the test vehicle to check whether the reverse connection protection is effective.

6.4 Mechanical safety test

6.4.1 Pedal static strength

Apply 3 times the maximum load (G) specified by the manufacturer to the center of the pedal through a support with a cross-sectional size of 150mm×150mm, as shown in Figure 2; and maintain for 5 min.

6.4.2 Entire vehicle load drop

Apply and fix the maximum load (G) specified by the manufacturer on the pedal of the test vehicle. Fix the rear wheel and raise the front wheel. When the front wheel is 200mm above the test surface, drop it onto a concrete or similar hardness flat surface, as shown in Figure 3. Repeat the drop for 3 times.

6.4.3 Pull-off force

The pull-off force test is carried out in the following manner.

6.4.4 Static load strength of handlebar

The handlebar strength test is carried out in the following manner.
