How to judge the quality of the Hydraulic Dumping Tricycle controller?

The importance of the controller to the Hydraulic Dumping Tricycle is self-evident. It is like the heart and brain of the Hydraulic Dumping Tricycle, maintaining the basic operation of the Hydraulic Dumping Tricycle. A high-quality controller can ensure the normal operation of the Hydraulic Dumping Tricycle and maximize the safety of the user.

However, a low-quality Hydraulic Dumping Tricycle controller is like burying a time bomb for the Hydraulic Dumping Tricycle, which also poses a great threat to the safety of the driver. So, how do we judge the quality of the Hydraulic Dumping Tricycle controller?

Although the controller is not so intuitive in the buyer's sight, we can still observe the condition of the Hydraulic Dumping Tricycle controller from different angles. Here are a few methods that do not require a lot of equipment and are easy to operate.

1. Carefully observe the workmanship

The workmanship of a controller reflects the strength of a company. Under the same conditions, the workshop controller is definitely not as good as the products of large companies; the hand-welded products are definitely not as good as the wave-soldered products; the controller with exquisite appearance is worse than the product that does not pay attention to appearance; the controller with thick wire is better than the controller with shoddy wire; the controller with heavy radiator is better than the controller with light radiator, etc. The company that pursues materials and craftsmanship is relatively credible, which can be seen by comparison.

2. Compare temperature rise

Use the newly delivered controller and the original controller to conduct the stall heat test under the same conditions. Remove the radiator of both controllers, use a car, prop up the feet, turn the handle to reach the highest speed first, brake immediately, do not brake to death, so as not to let the controller enter the stall protection, maintain at an extremely low speed for 5 seconds, release the brake, quickly reach the highest speed, brake again, repeat the same operation, for example 30 times, and detect the highest temperature point of the radiator.

Compare the data of the two controllers, the lower the temperature, the better. The test conditions should ensure the same current limit, the same battery capacity, the same vehicle, and the same test starting from a cold car, with the same braking force and time. At the end of the test, the tightness of the screws fixing the MOS should be checked. The looser the screws are, the worse the temperature resistance of the insulating plastic particles used is. In long-term use, this will cause the MOS to be damaged prematurely due to heat. Install the radiator again, repeat the above test, and compare the radiator temperature, which can examine the heat dissipation design of the controller.
