What are the detailed steps for the brake performance test of an electric wheelchair?
The brake performance of an electric wheelchair is one of the key factors to ensure user safety. According to national standards and test methods, the following are the detailed steps for the brake performance test of an electric wheelchair:

1. Horizontal road test

1.1 Test preparation
Place the electric wheelchair on a horizontal road surface and ensure that the test environment meets the requirements. It is usually carried out at a temperature of 20℃±15℃ and a relative humidity of 60%±35%.

1.2 Test process
Make the electric wheelchair move forward at the maximum speed and record the time taken in the 50m measurement area. Repeat this process four times and calculate the arithmetic mean t of the four times.
Then make the brake produce the maximum braking effect and keep this state until the electric wheelchair is forced to stop. Measure and record the distance from the maximum braking effect of the wheelchair brake to the final stop, rounded to 100mm.
Repeat the test three times and calculate the average value to get the final braking distance.

2. Maximum safety slope test
2.1 Test preparation
Place the electric wheelchair on the corresponding maximum safety slope to ensure that the slope meets the design requirements of the electric wheelchair.
2.2 Test process
Drive from the top of the slope to the bottom of the slope at the maximum speed, the maximum speed driving distance is 2m, then make the brake produce the maximum braking effect, and maintain this state until the electric wheelchair is forced to stop
Measure and record the distance between the maximum braking effect of the wheelchair brake and the final stop, rounded to 100mm.
Repeat the test three times and calculate the average value to obtain the final braking distance.
3. Slope holding performance test
3.1 Test preparation
Test according to the method specified in 8.9.3 of GB/T18029.14-2012
3.2 Test process
Place the electric wheelchair on the maximum safety slope to evaluate its parking ability on the slope to ensure that the wheelchair will not slide without operation.
4. Dynamic stability test
4.1 Test preparation
The electric wheelchair shall meet the tests specified in 8.1 to 8.4 of GB/T18029.2-2009 and shall not tilt on the maximum safe slope
4.2 Test process
The dynamic stability test is carried out on the maximum safe slope to ensure that the wheelchair remains stable and does not tilt during driving and braking.

5. Brake durability test
5.1 Test preparation
According to the provisions of GB/T18029.14-2012, the brake system of the electric wheelchair is subjected to durability test to ensure that it can still maintain good braking performance after long-term use
5.2 Test process
Simulate the braking conditions in actual use and conduct repeated braking tests to evaluate the durability and reliability of the brake.
Through the above steps, the braking performance of the electric wheelchair can be fully evaluated to ensure that it can provide effective braking force under various conditions to ensure the safety of users. These test procedures follow national and international standards such as GB/T 12996-2012 and GB/T 18029 series standards
