Fault analysis of electric vehicles

( 1 ) insufficient tire pressure will increase tire friction and road surface , thereby reducing Continued mileage ; handlebar rotation flexibility will enable to reduce the impact of riding comfort and safety. Should be less pressure to replenish pressure, tire pressure should be in accordance with the provisions of the "electric bicycle manual " in the recommended tire pressure or surface pressure .
( 2 ) handlebar rotation is not flexible, catching point when stiff or tight spot , should be timely lubrication or adjustments. Lubrication general use butter , calcium or lithium grease ; Electric Bicycles adjustment , release fork lock master , rotating fork stop , when the handlebars turn the flexibility to meet the requirements , you can lock nut locking fork .
( 3 ) the flexibility of front and rear wheels turning bad , will increase the rotational friction, increase power consumption , thereby reducing Continued mileage . Therefore, once the fault should be timely lubrication and maintenance , lubrication general use butter , calcium or lithium grease ; If the shaft skin fails, you can replace the ball or shaft skin , if the electrical fault should go to a professional repair unit maintenance.
( 4 ) circuit inspection, turn on the power electric scooters switch , check the circuit is smooth, solid and reliable connectors are plugged , whether the fuse is working properly, especially connected with the output terminal of the battery cables are secure and reliable. Found fault should be immediately removed .
( 5 ) before the trip , check the battery charge , according to the judgment of the battery power is sufficient mileage to travel . If the power is not sufficient manpower should be supplemented by appropriate riding, avoid battery undervoltage work .
( 6 ) It should also be checked before traveling the working conditions of the motor. Starter motor and adjust its speed to observe and hear the motor running , if abnormal, should be timely maintenance.
( 7 ) should be checked electric lights, horn and other former bicycle use , especially at night travel. Headlights should be bright, light should generally fall in the range of 5-10 meters in front of the front ; horn should sound loud, not hoarse ; turning lights should be flashing normal , indicating normal steering , lights flicker frequency of 75-80 beats / min ; Meter display should be normal .
( 8 ) should be checked before traveling all the major fasteners are tightened , such as the horizontal tube , the riser, saddles, saddle tube , front, rear, bottom bracket , lock nut , pedal and other fasteners should not loose fasteners loose or fall off if there should be tightened or replaced promptly . The recommended torque fasteners generally: the horizontal pipe, the riser, saddles, saddle tube , front wheel , pedal to 18N.m, mother and rear wheels to lock axis 30N.m.
