Electric car when the motor when the stop, how to repair? There are six major failures!

Electric vehicles as a result of economic convenience has become the preferred public transport vehicles, in the use of electric vehicles in the process, the occasional riding when the motor when the time to stop the situation, which is what causes it, how to repair?

Troubleshooting 1: The controller controls the voltage close to undervoltage protection.

In order not to damage the battery, the controller will "set" a certain voltage protection value, once violated immediately power off! General 48-volt battery undervoltage protection value of 41-42 volts, 60-volt battery undervoltage protection value of 52-53 volts, when the battery power to close to the undervoltage value, the power to pick up, riding a section of the road back to the Pressure point, there will be riding when the turn does not turn the phenomenon! When the battery is no electricity, it should immediately power, forced by the rebound voltage driving, will hurt the battery.

Solution: the battery does not cause the motor when the motor when the stop, you can implement the electric car quickly charge.

Eliminate fault 2: caused by motor phase loss.

General brushless motor is divided into three phases, the lack of any phase, the motor is not normal operation, and some riding trembling, and some motor work abnormalities, noise, forced riding because of lack of phase and let the motor fever, riding " Knock Deng Deng knock Deng "when it should be promptly repaired, do not because of small problems caused by motor scrapped! Phase error is mostly motor Hall, the original motor is a magnet control sensor, it can detect changes in the magnetic field, through the controller according to the Hall to collect the signal to control the controller's three-phase output, so that Motor normal operation, once one of the Hall "strike", the motor inside the "messy", and lead to the lack of motor when the time does not turn or jitter!

Solution: replace the fault Hall, restore the motor inside the normal "order", so that the rotation does not shake.

Troubleshooting three: electric car line due to water.

Electric car by the line lap transmission, the line connector has a number of connectors for plugging, if the water will cause contact when not in contact, the electric car will be when the time to stop, especially the handle to connect the connector and brake power Connectors and motor Hall connector water short circuit caused by rainwater weather as far as possible do not go to the depth of the water ride, trample the water, splashed on the line, may "power outage."

Solution: connectors are easy to encounter places with water insulation to isolate, as far as possible to the height of the fixed, so as not to suffer from water "bullying."

Troubleshooting four: speed caused by the failure.

Turn the handle is an important part of the control speed, often turn, the damage rate also increases, when the speed of the damage is likely to cause the electric car does not turn or intermittent turn. Turn the line is generally three lines, the red is to turn the positive 5 volt power, black line is negative, the green line is the signal line, the speed will disconnect the plug, with a multimeter red pen contact controller plug side of the red line, black If the measured voltage is five volts, it means that the controller is normal for the power supply, plug the plug with a multimeter's black pen to touch the black line of the metal sheet red pen touch the green metal sheet, turn the speed control, Multimeter transferred to 20 volts stalls, if the change with the description of 1-4 V to turn the normal, otherwise turn to a fault.

Workaround: replace the speed control! After the wear and tear caused by poor contact, resulting in time to stop.

Troubleshooting five: the controller internal failure caused.

The controller is the command of the electric car, control the motor running speed, is the electric car's core components of the electric system, the controller drives the motor rotation, under the control of the handle can change the motor drive current, to adjust the speed of the effect The The controller has a certain over-current protection, when the load overload will automatically power, to protect the controller and the motor from damage, there will be time to stop when the phenomenon! In addition, some manufacturers do not pay attention to the details of the controller is not fixed, encountered bumpy road is easy to control the internal "components" welding point Britain "virtual access", resulting in short circuit, resulting in the motor does not turn or when the time to stop.

Solution: replace the controller, its fixed, to avoid bad.

Troubleshooting 6: Poor battery connection and fuse.

The battery is in series, a battery connected to a piece of which the battery pile on the cable connection is not good when the power will not power, the car will be the time to stop, so the best way to repair in time, or " Easy to spontaneous combustion and easy to burn the battery pile, the solution: re-welding, welding solid, it is best to use the insulation tape on the tape wrapped, the second insurance to prevent the line from the battery pile again fall off. The fuse in the battery once the load current is large, the battery line from the heat, the line will be short-circuit will "melt" off insurance, the line, the battery play a protective role, but when the fuse is bad, it is easy to chargers, Charging the fuse from the heat burning, will also lead to poor contact resulting in the time to stop.

Solution: Replace the entire fuse holder and fuse.

Electric car to bring convenience, usually have to care for electric cars, failure to resolve in a timely manner, so as to avoid major problems of major problems. Electric car when the stop can not be forced to ride, electric car repair division to help you solve problems! Let the original depressed electric car, rebuild glory, restore power!
