Points for pre-service maintenance of electric bicycles
1 chain: the laxity of the chain shall be checked before the electric bicycle functions. The chain is over-stretched and laborious, while the pine is prone to tremors and rubbing other parts. The gradient of the chain is appropriate at 1-2 mm and can normally be appropriately tightened when riding without a foot。
Tyres: if the tire pressure on an electric bicycle is insufficient, it will increase the friction of tyres and pavements, thereby shortening the continuous mileage; it will also reduce the mobility of vehicles and affect the comfort and safety of riding. The pressure should be replenished in a timely manner when it is insufficient。
3. Vehicle handles: the wheel is not flexible, and when there is a brake, rigidity or tightness, it should be lubricantsed or adjusted in a timely manner. Lubrication generally uses butter, calcium or lithium-based lubricant; when adjusting, the pre-fork locker is released, the pre-rotation forklift is blocked, and the pre-fork locker is locked when the flexibility of the vehicle to move is met。
Lights: before the use of electric bicycles, lights, horns, etc. Should be checked, especially for night trips. The light shall be bright and the beam shall normally be in a range of 5-10 m in front of the head; the light shall be scintillated 75-80 times/minute; and the instrumentation shall be normal。
Batteries: before travelling, electric car batteries should be checked and the adequacy of batteries should be judged on the basis of the mileage travelled. If electricity is not sufficient, it should be appropriately accompanied by a human cycling to avoid battery stress。
Power: the work of the electric power should also be checked before travelling. Activate and adjust the operation of the retrofit and hearing machines and, in case of anomalies, maintain them in a timely manner。
Maintenance point at use
1. Electric bicycles shall, to the extent possible, not use zero-starting (i. E., in situ), especially at loads and slopes. On start-up, it shall be carried by a man, at a certain speed, before being converted to electric or directly by electric aids. This is because, at the start-up, the electric power must first overcome the equilibrium friction, when the current is large, close to, or even reaches, the blockage of the current, allowing the battery to work on large currents and accelerate damage to the battery。
2. When riding on an electric bicycle, use as much as possible manual or electric aids, in particular when uphill, heavy, windy or road-blocked, it must be accompanied by manpower. In this way, long-term large-scale electrical discharges of batteries can be avoided and damage to batteries can be beneficial for increasing the continuous mileage of a charge and extending the useful life of the batteries。
3. Electric bicycles are not adapted to roads that are strained or sloped over steep (usually 8°). In the event of such a road, it should be slowly driven or driven off the vehicle. Under this road, the poor working environment of electric generators, controllers, batteries, etc. Will reduce the useful life and are vulnerable to damage。
4. Electric bicycles should be operated in a manner that avoids frequent brakes and start-ups, before or at the same time should be rotated back and, to the extent possible, should be driven by manpower in areas where the roads are in favour. In this way, damage to batteries can be avoided by large currents at start-up。
5. The standard load weight of electric bicycles is 75 kg and overload should be avoided as much as possible. In the case of overloading, manual riding and manual mobility should be used。
6. The use of electric bicycles in cold weather shall be supported by as much manpower as possible or by electric power; and attention shall also be paid to the power and voltage of the batteries, which, in general, should be properly reduced to discharge depths and must not travel in a state of pressure. This is due to reduced charge and discharge capacity of batteries in cold weather。
7. Electric bicycles are not afraid of snow and rain. However, the water level at which the water is accumulated cannot exceed the lower line of the electric wheel bearings to prevent damage from the electrical inflow. When riding on a rainy and snow day, it should be wiped clean as soon as possible; if electrical equipment is soaked, it should also be dried with a wind blower. In order not to cause iron corrosiveness and electrical failure, short circuits, etc。
The speed of the journey should be reduced appropriately in the rainy and snow days, and brakes should be careful to increase brake distances and prevent side slides and turnbacks from endangering personal safety。
9. Electric bicycles shall avoid long periods of sunlight exposure and shall be stored in the shade. Solar exposure accelerates the ageing of paints, plastics, rubber and electronic components and reduces their useful life and reliability。
10. Electric bicycles shall be stored in cold, ventilated, dry and far from corrosive liquids and gases; the whole vehicle shall be kept in a straight state, with sufficient pressure on the tyre; no heavy load shall be carried on the vehicle body; and the storage cells shall be kept separately。
Electric bicycle maintenance
1. An electric vehicle shall, before being used, be careful to check whether the vehicle is in good condition, such as the adequacy of the tyre pressure, the sensitivity of the brakes, the sound of the whole vehicle, the looseness of the screws and the adequacy of the battery。
2. At the beginning of the start-up, the vehicle shall be slow to accelerate to avoid instantaneous and abrupt acceleration of damage to the object. In order to extend the life of batteries and electric generators, foot-to-peed or bandwidth boosts are applied when vehicles start or climb。
3. Subject to safety guarantees, frequent brakes and start-ups should be minimized to save electricity. The brakes should be released so as to avoid damage to electric and other appliances (the new vehicles are now usually equipped with automatic power outages, but be careful). When you get out of the car, the power should be turned off in case of an accident when you do not intend to turn the switch on it。
4. Charging should be careful not to use chargers in other brands, each of which matches the performance of the battery. Optimal charging can be achieved only by specialized chargers。
5. Chargers contain high-pressure lines and are not removed without permission. When charged, the charger shall not cover any articles and shall be placed in the ventilation area, while taking care to prevent liquid and metal particles from entering the charger's interior and from falling and impacting in order to avoid damage。
6 . There is a loose screw in the parts of the electric bike, etc., which needs to be re-established in a timely manner. If abnormalities are found in the rides and cannot be repaired themselves, the repair shop should be contacted and repaired in a timely manner。
7. Batteries shall be recharged using chargers of matching or manufacturer-specified models, which may not be used intermingled; when charged, the battery and chargers shall be located in the cool area of ventilation, securely placed, far from the flammable and explosive material, avoiding high temperatures, dampness and beams, prohibiting the covering of articles and prohibiting contact with young children. After charging, the grid is disconnected and the charger is disconnected from the battery. Lead-acid batteries typically take 6-8 hours to charge。
8. Accumulation batteries shall cease to be used and be recharged at an early stage, with the prohibition of the return voltage of the batteries and the prohibition of deep discharge and overcharge of the batteries, preferably with a view to keeping them in a plentiful state. It is recommended to charge at least once a day。
9. Storage cells shall be stored in cold, air-moisture locations, and the batteries shall be kept standing; they shall be stored for long periods of time in sufficient quantities and shall be replenished periodically, normally once a month. Lead-acid batteries are stored for long periods of time and can be injected with a few drops of distilled water to offset the water evaporation and reduce the sulfurization of the polar plate。
Maintenance of electric vehicle batteries
The lifetime of electric car batteries is critical. General electrical motor failure is low, but battery life is much shorter. The majority of electric bicycles currently sold on the market use lead acid batteries with no memory effects, and there are many descriptions of the best methods of charging lead acid batteries, which can be summarized as follows:
Charges to avoid "deep discharge". The motor vehicle is used to charge the day, and every day, however far, it is best to fill up the battery and not wait for the battery to be recharged。
2. The battery shall be charged in the vehicle by closing the door lock and not by recharging the battery in reverse and filling it as much as possible. The charging and post-sale service repair should be stopped immediately if the charge is smelly or the battery is too hot. When batteries are charged, no metal, such as wet hands or keys, should be used to reach both ends of the electrode to avoid burns。
3. When used for a long period of time, charge every month, fill the battery with electricity and store it in the absence of a deficit。
4. Charges shall be made with a special charger. Since battery formulations differ from process to process and the technical requirements for chargers differ, which charger batteries can fill and vary from one brand to the next, so do not mix chargers。
5. Batteries may be charged whenever they are protected, but no return voltage can be used to prevent severe power losses, and when the batteries are not powered, the power cycle shall be shut down。
6. When charged, the charge sign indicates that the charge shall not be stopped immediately when fully charged and that the charge shall be floated for two to three hours。
There's an unknown number of common malfunctions on electric bikes
1. Check if there is a shortage of oil on the front contour counter (also known as a metre or turbine) or on the front line, if any, with butter
2. Checking whether pre- and post-wheel slabs are loose enough to bind tyres while travelling
3. Checking for contact with and friction of the remnant box
4. Check if there is a lack of fuel in the fork behind the frame (i. E. A steel frame with a fixed electric generator) and in the screw where the frame is connected, and if so, butter
Add: there's no point of contact, no screws, no screws
There's an unusual noise in the brakes
1. Check whether the pre- and post-wheel drive brakes have been worn out or are nearly worn out, and some of the local brake blades have been fully defaced with dew
2. Check if the brakes are worn (whether the regular contact with the brakes is significantly lower than the unexposed)
3. Check whether the brake blades were uneven as a result of inappropriate installation adjustments (dismantling of the brakes to see if there is a clear one-side high or one-side low)
Four, two brakes in the middle slightly above two
5. If a drum brake is used, check whether the brake performance is significantly reduced and whether the brake schedule significantly exceeds the state of the new car, and if so, replace the new drum brake
6. Repositioning of drum brakes and electric caps, axle axes and frame anchors, or drum brakes and frame locator tablets if new drum brakes sound
When riding, it clearly feels like it's turning in one direction
1, if new, check if the front and back axis is the same line
2. Identification of any distortion of direction due to long load overload or accidental crash, fall, fork, poles, and direction
3. Check if the pre- contours are at the epicentre of the earthquake, no apparent deviation tilt
Four, try to increase the direction with a big drill and connect to the pole
When you start or turn, it's clear you're shaking
One, check if the pointer connects to the pole
2. Check if the pole connects to the frame and locates the large nut (slight, two, commonly known as the nine fork first set) loosely and, if so, tighten it properly
3 on the basis of the length of use, it is judged that the nine pieces were worn up and down
Four, check if both ends of the front wheel locator are loose
When you ride, you feel the whole car shaking for an unknown reason
1. Check for pre- and post-temporal pressure
2. Checking for good resilience to pre- and post-earthquake
3. Air-turned round-and-round wheel, carefully confirming whether there is a visible axle-string (right-and-right swing) and, if so, replacement of bearings
Check whether there is a clear run-off (asymmetrical between the left and right treads and the wheel) of the tyres, and if so, reposition them after venting, as the deformed tyres have been replaced as a result of prolonged deformation pressure。
