The controller component battery powered mountain bikes burnout reason

1, in use, battery powered mountain bikes reverse the positive and negative power supply,
2, the controller water, causing a short circuit element burned out,
3, the battery powered bicycles controller circuit board components or bad,
4, sealing off the circuit board components, Weld.

battery powered mountain bikes Chargers continue to heat up

Battery powered mountain bikes spontaneous combustion during the charging process, the charger because the majority of the short-circuit, short circuit due to overheating, due to overheating of the battery operated tricycle charge time is often too long. An industry source said that at present the majority of electric car chargers do not have to use the automatic power-off protection, although many battery powered bikes chargers on the market are equipped with fans and other cooling devices, "in the charging process, the fan will rotate ; However, after fully charged, the fan will stop. "Then, after the electric car charger fan stops have much influence on the charger? According to reports, although the full charge, the charger will automatically turn on the green light, but in fact the input power is still slow, if not promptly cut off the power supply, it will cause the charger to overcharge. Test was done under overcharge cases, chargers will continue to heat up, not only easily lead wire aging, but also easily lead to a short circuit due to overheating, sparking a fire.

battery operated bicycles charging machine use and maintenance

1, electric powered bicycles AC power outlet must plug the AC charger matched.
2, should be more stable AC voltage variation should not exceed 10% of the 220 ​​persons.
3, before using the battery operated bicycles charger, please read the instructions carefully charger.
4, the charging procedures: electric lock switches off the vehicle, charger plug into the battery of the total output DC plug, then the AC input plug the charger into an AC power outlet.

battery operated bicycles manual cleaning

In the shade until the battery operated tricycle body temperature drops below 40 degrees Celsius, and then cleaned.
With a battery operated bicycles hose to wash away loose dirt;
Wash with a mild cleaning agent for battery powered bicycles, cleaning agent should be mixed according to the manufacturer's instructions, with a soft cloth moistened with cleaning fluid, do not rub hard, so as not to damage the paint.

battery operated bicycles disc repair

Determine runout is caused by what . Inspection methods: support from a large front wheel off the ground , light hand turn the wheel, find much resistance areas. That point grinding disc , battery powered bicycles marked with a red marker . And in the three bolts marked 1,2,3, serial number , and remember the original installation location.
1 , remove the front wheel . Then remove the battery powered bikes disc . This is the most troublesome , is a bit difficult , screwing the bolt must be struck with a hammer in front of three hexagonal , or hexagonal plate wring also screwed down.
2, the discs get clean , put on a clean glass , the disc without side down stairs . With a thin piece of paper next to the hard disc plugs, as are stuffed into, explained the disc is not deformed , said Mingrui face runout caused by the wheels .
3 , the Electric Bicycles disc must be relatively flat deformation . This is not difficult , you have friends in the machine shop of the most easy.
4 Wheel Swiss uneven surface will use the compensation method . That method in 1.2.3 plus sheet position among the added sheet , the sheet is cut into the skin of cans ( thickness 0.12MM). Combination of the above grinding disc plus point to determine the location of the sheet , depending on everyone's analyzes .

battery powered bikes several advantages

With the rise in oil prices in recent years, battery operated bicycles industry wells:
The following briefly say the advantage of battery powered bikes:
1 low price, nice
2 operating threshold is low, no driving license, driver's license.
3 high security performance, when speed is not more than 50KM, maximize reduce accidents,
4 battery tricycles closed, convenient travel, the elderly and children to reduce wind and rain
5 green, pollution-free.

How to quickly find faults battery powered bike

  Repair of Flyhorse battery powered bikes in two steps, namely, troubleshooting and repair. The premise and the key is to quickly find fault repair.
 First, the car does not turn (ie, the motor does not rotate)
    1, the use of electric vehicles detector test whether the voltage of the motor leads can immediately determine the fault lines and control lines. Measurement result is voltage, then determine: bad motor or motor controller to the lead circuit fault and should be excluded. No voltage measurements, it is determined: control line failure, the next step should be checked.
     2, the brake controller plug off, and then turn the power switch to. Turn the car, then the judgment: brake switch is bad, has caused a short circuit fault, you should get a new brake switch. If the car does not turn, you then transfer to a good governor, replacing the original transfer. As the car rotates, the judgment: the original to the governor is bad, causing the electric car does not turn, should get a new controller.
     3, measuring the battery compartment contacts can be judged immediately by causing the car does not turn the power section of the fault. If no voltage is displayed, turn the power locks, dashboard lights are not lit, determine: Fuse Fuse broken, should be replaced by fuses, wires off, welded wire breakage or should be renewed. If the voltage is displayed, turn the power locks, dashboard light does not shine, it is judged, power locks broken, the lock can be renewed without electricity.
 Second, turn on the power lock, turn the car stop (surprise car phenomenon), brake car
     Detection method is to control the speed regulator turn off the plug, can be determined to the governor or controller failure immediately.
 If the plug is disconnected to the governor, open the electric door lock car does not turn, determine: the governor to have been bad; If you disconnect the governor put the plug, open the electric door lock, the Flyhorse battery electric bicycle still turn, determine, control is already bad and should be replaced.
