How to determine the cargo trikes merits of the controller

Back pressure control observed

      Select a cargo trikes , power can be bigger , unplug the battery charger for electric vehicles powered choice , connect terminals E-ABS is enabled , the switch to ensure good contact with the brake . Slowly turn the rotating , fast charger can not output large current will cause voltage, so that the motor reaches top speed , rapid braking, repeatedly, should damage occur MOS phenomenon during cargo electric bikes braking , the charger output terminal voltage will rise rapidly , the test controller instant pressure limiting the ability of this test if the battery test basically no effect. This test can also be performed in the fast downhill , when the car reaches the high speed braking.
Current control
Take full battery capacity the better , let the motor reaches top speed , optional two motor output line short , repeated more than 30 times, should not appear MOS damage ; let the motor reaches top speed , with the cargo bikes battery positive and optionally a motor line short , repeated 30 times , which is more severe than the test , a MOS circuit of less resistance, greater instantaneous short circuit current, rapid control of the test controller .
Many controllers fool in this part , if damaged, can compare the number two controllers successfully withstand a short circuit , the less worse ; unplug an electrical cord, turn to pull the maximum , then the motor will not run quickly turned the other motor lines, should be able to turn the motor immediately , the motor rotation in which a motor repeatedly plug wire , the controller should work . This part of the experiment to verify the controller software , hardware reliability design .

cargo trikes Battery Maintenance

Maintenance-free battery does not mean no maintenance. In fact, the origins of this term maintenance-free battery is for opening the cargo bikes battery (scientific name: dry-charged batteries) to be supplemented with the use of pure water comes, that is cargo electric bike maintenance-free batteries in the process does not require the use of additional pure water only, not it does not require maintenance. Maintenance-free battery has many advantages: for example, self-discharge, in use less water loss, good high-current discharge performance, acid does not overflow. However, maintenance-free batteries battery than the opening "stingy", mainly in the charging session. When we use the charging needs on the ground, such as the long-term over-discharge, less filling, etc., according to factory specification requirements must be charged, otherwise the cargo bicycles battery will be deformed, etc.; in the car charging voltage must be controlled at 13.8V-14.4V between, or the charge voltage is high, resulting in the rapid loss of water you can not pay; charging voltage is low, the battery may cause long-term due to charge the internal battery plate sulfation, the sulfated if severe, treatment is difficult, because it is sealed.

cargo electric bicycles motor classification

Throughout the Flyhorse cargo electric bikes motors, from the current situation in the industry to use point of view, there are two main motor: efficient rare earth permanent magnet brush motors and high rare earth permanent magnet brushless motors, Flyhorse cargo electric bicycles currently on the market, most have been from a brush Motor phase into phase brushless motor. Between the two, the brushless motor is better than a brush motor. According to current market research, brushless motor has basically replaced brushed motors. Electric vehicles will usher brushless motor stage.
     The first brush motor: brush motor with mechanical commutation, low technical requirements for the control system, the relative cost less than brushless motor, brush motor starting torque is slightly larger than the brushless motor. But the fatal weakness is: Life is short, noisy and inefficient. It is a serious long-term use brushes to wear, easier to damage. Meanwhile worn toner dust generated a lot of these dust falling gear oil, gear oil accelerates dry, Flyhorse cargo trikes motor noise is further increased. Use a brush motor to be replaced within a year or so brushes, you will find the charging time is less than two-thirds of the mileage when you bought a new car, but underpowered when climbing, but also burn the controller. This is because the replacement motor brushes, commutator also grind a groove, so that the contact area to reduce the carbon brushes will produce a spark after poor contact brushes and commutator energize and accelerate the oxidation of copper, lead above undesirable phenomena.
     The second brushless motor: brushless motor with electronic commutation replace mechanical commutation, technically superior to brush motor. Since the brushless motor without gear reduction device, or to reduce the wear of the motor is not reliable. Its efficiency within a certain range than current high brush motor efficiency. Brushless motor driving up almost no noise, and long life of more than 10 years.
