When purchasing a Hydraulic Dumping Tricycle, you should consider the specific situation.

1. Observe the reverse pressure control ability of the Hydraulic Dumping Tricycle.

Choose a vehicle with a larger power, unplug the battery, select a charger to power the Hydraulic Dumping Tricycle, connect the E-ABS enable terminal, and ensure that the brake switch has good contact. Slowly turn the handlebar. If it is too fast, the charger cannot output a large current, which will cause undervoltage. Let the motor reach the highest speed, brake quickly, and repeat it many times. MOS damage should not occur.

When braking, the voltage at the output end of the Hydraulic Dumping Tricycle charger will rise rapidly, testing the instantaneous voltage limiting ability of the controller. This test is basically ineffective if tested with a battery. This test can also be performed when going downhill quickly, and the car brakes when it reaches the highest speed.

2. Current control capability

Connect a fully charged battery, the larger the capacity, the better. First, let the motor reach the highest speed, short-circuit any two motor output lines, repeat for more than 30 times, and no MOS damage should occur; then let the motor reach the highest speed, short-circuit the positive pole of the battery and any motor line, repeat for 30 times, this is more severe than the above test, there is one less MOS internal resistance in the circuit, the instantaneous short-circuit current is larger, and the controller's current fast control capability is tested.

Many controllers will be embarrassed in this link. If damage occurs, the number of times the two controllers successfully withstand short circuits can be compared, the fewer the worse; unplug one motor line and pull the handle to the maximum. At this time, the motor will not run. Quickly connect another motor line, the motor should be able to rotate immediately. Repeatedly plug and unplug one of the motor lines while the motor is rotating, and the controller should work normally. This part of the experiment can verify the reliability design of the controller software and hardware.

3. Check the efficiency of the controller. Turn off the overspeed function, if any, and test the maximum speeds reached by different controllers in the same vehicle without load. The higher the maximum speed, the higher the efficiency and the longer the range.
