Battery Charging and Maintenance
1.
Charger is dedicated, and shall not be replaced at will.
Parameters of chargers equipped for different
vehicle models are basically different, so the chargers shall not be replaced
at will in case of uncertainty. If charging in two places is required, then it
is better to equip the other one original special charger of the company.
2. Protect
the charger well.
The charger is not designed as vehicular
charger when design, so existing chargers do not basically bear strong
vibration, accordingly, generally chargers shall not be put in trunk and basket
of electric bicycle. In case of moving under special condition, the charger
shall be well covered with foamed plastic to prevent occurrence of vibration resulting
in bump. Internal potentiometers of many chargers after vibration may drift,
thus making the whole parameter change, resulting in abnormal charging state. In
addition, what needs attention is that keep ventilation of the charger when
charging, otherwise it may not only influence service life of the charger, but
also possibly generate thermal drift, thus influencing charging state, and it
may damage the battery. (Generally involved in charger instruction)
3.
Frequently charge the battery.
Even if your full charge endurance is not
long, and the battery can be used for 2-3 days after being charged, we still suggest
you charge it every day, accordingly, the battery will be made shallow
circulation state, and the lifetime of the battery may extend. Some users early
using mobile phones think that the battery shall be charged after being
basically used up, the opinion is wrong, the memory efficiency of lead-acid
battery is not that strong. Usually charging the battery after fully
discharging is of great influence on the lifetime of the battery. After the indicator
light of the charger changes to indicate that the battery is fully charged,
actually electric quantity charged into the battery may be 97%~99%. Though
there is only 1%~3% of electric quantity lacked, the influence on the full
charge ability can be ignored, it may also form insufficient charging
accumulation, so the battery is better for continuous floating charge as far as
possible after indicator light of the charger indicating full charge changes,
and it is beneficial for restraining battery vulcanization. Floating charge basically
may not consume the power.
4.
Timely charge the battery.
The vulcanization of battery starts after
discharging, and generally obvious vulcanization crystallization occurs
starting from 12 hours. Timely charging can eliminate slight vulcanization
crystallization, in case of untimely charging, these vulcanization
crystallizations will accumulate and gradually form thick crystallization, thus
gradually resulting in decrease of battery capacity, shortening the service
life of the battery. Therefore, except daily charging, also pay attention to
timely charging the battery after using up to make the battery level full as
far as possible.
5.
Periodically discharge deeply.
Periodical deep discharging of the battery
once is helpful for “activating” the battery, being able to slightly improve
battery capacity. General method is that periodically fully discharge the
battery. The method for full discharging is that ride the bicycle on the flat
road surface under the normal load till low-voltage protection for the first
time. Pay attention to that: we specially emphasize the first low-voltage
protection. After the first low-voltage protection of the battery, voltage of
the battery may rise to recover to non-low-voltage protection after a period of
time, at the moment if the battery is reused, the harm to the battery is great.
After completion of full discharging, fully charge the battery, and the battery
capacity may promote.
6.
Form some good habits of electricity saving.
Slide as far as possible, and slide in
advance to decelerate as far as possible when traveling downhill. Enter into
sliding in advance when being to meet traffic lights to reduce braking to the
maximum limit.
When starting, slowly turn the handle, it
may relatively be safe and avoid impact of high current on the battery, and it
may reduce power loss and life expenditure of the battery.
7.
Pay attention to environment for charging.
Currently chargers for electric bicycles
are designed as per environmental temperature of 25℃, so charging
under the condition of 25℃ is better. However, there are few moments that the environmental
temperature is 25℃, accordingly there are inevitable problems of over-charging in
summer and under-charging in winter. Therefore, it is better to arrange the
battery and charger under environment with room temperature and ventilation for
use when charging. (Place where indoor air ventilation is good)
Special tips: if the battery enters from
outdoor low-temperature state into warm room in winter in north China, the
battery surface may generate frost and condensed dew. In order to avoid battery
leakage caused by frost and condensed dew, charge the battery after battery temperature
rises approaching indoor temperature after drying.
Use and Maintenance of Motor
Technical parameters of motor
Electric bicycles of the company adopt
hub-type rare-earth permanent magnet brushless DC motor with high output torque
and high workspace efficiency etc. excellent features.
Electric hub structure
Electric hub is direct-drive type, as the
rotor of brushless permanent magnet DC motor, the rear wheel is embedded with
rare-earth permanent magnet; armature winding is fastened on the shafting. Electric
hub may produce certain noise during starting, being normal phenomenon.
As to the electric hub of the
electric bicycle, it is normal phenomenon that the rear wheel is laborious, when
the electric bicycle is moving backward, or the electric hub makes slight sound
in moving forward.
Internal maintenance of electric hub
Electric hub needs no special maintenance
at ordinary times, when the electric bicycle is accumulatively ridden for 1000 hours;
please go to professional maintenance service center for professional
maintenance, including inspection of wear state of bearing mechanism in the
motor and waterproofness of the shafting etc.
External maintenance of electric hub:
During the use of electric bicycle, pay
attention to inspecting the state of fasteners in electric hub installed on the
rear fork piece, in case of nut looseness, timely screw down the nuts.
Important
Notice
When riding on the road with gathered water
in rainy day, the electric bicycle can be normally ridden in case the depth of
gathered water does not exceed electric hub axis, and in case the depth of
gathered water on the riding road exceeds electric hub axis, it may cause water
permeating to the motor, thus resulting in motor fault, please pay special
attention to that.

supplement the electricity in the battery full no matter how far the distance
will be through riding each day, and charge the battery before the electricity
is used up.
Other
important notes
1. Contact of the battery box exposed outside
is electrified, strictly prohibit children touching with hands, as it may cause
short circuit resulting in electric injury, and strictly prohibit conductive
materials touching contacts at two ends at the same time, as it may cause high
current short circuit which may produce electric arc resulting in accidents.
2. Battery and charger under charging shall
both be placed in safe place where children are unable to touch.
3. When using and storing the charger,
prevent fluid and metal particles from permeating in the charger so as to
prevent internal short of the charger which may damage the charger.

The charger will generate some heat during working. Never put any combustibles
such as combustible plastics or foams under the bottom of the charger; and
never cover any articles on or around the charger; please put the charger in a
well ventilated environment. If you smell the smell or find the temperature of
the charger shell is over high and the shell surface temperature is higher than
65℃ during the charging,
please stop charging and send the charge to the maintenance department for
overhaul.
5.
Never charge the battery with a charger of other brands, and the battery of
other brands shall also not be charged with this charger, only if professional
test and adaption.
Important Notice
When
the charger or the battery goes wrong, it is possible that the charger
indicator does not change color for a long time (generally longer than 12h),
the charger keeps red and the battery generates relatively high heat, please
instantly stop charging the battery.
Controller
Maintenance
The
controller has the function of undervoltage, current limiting and overcurrent
protection, controls the major loop of the electric bicycle, has a large
current and will generate heat. Thereby, try best to be slow and ride steadily
and try best to reduce the starting and working current when starting and riding
the electric bicycle; when using the governor handle, please be careful and
rotate it lightly; do not park the electromobile under the blazing sun for
quite a long time and do not get it wet in the rain for a long time, so as to
avoid fault of the control.
The
controller has been adjusted to be the best state when delivery. If any fault
or runaway of the electrical equipment during the riding, non-professional
maintenance personnel can only check the cables and connectors, and should instantly
contact professional maintenance point or factory if he can’t solve the
problem.
The necessary items for electric bicycle use and maintenance
1. The
electric bicycle cannot be put under high temperature for a long time,
especially in hot summer, and the burning sun will affect the color and luster
of the bicycle paint. And the environment temperature that is higher than 50℃ will affect the normal work of
the electrical equipment.
2. Do not ride
the bicycle to the hollows. Battery and the electromotor of the electric
bicycle weigh 70---80kg and its cyclist weighs 50---80kg, the thin aluminum
wheels cannot bear excessive vibration, it may deform or even break, thereby,
pay attention to the road condition when riding the bicycle.
3. Never make the battery contact any metal objects in order to
avoid the short circuit of the positive and negative electrodes.
4. Prohibit
wading into water. When the water drowns the controller cables and motor, short
circuit may happen, which may do harm to the electrical equipment.
5. The electric
bicycle motor is in the hub of the rear wheel, and power of the battery
connects with the rear-wheel motor through right controller with a bunch of
wires, be careful of the electric circuit when replacing the rear tyre and disassembling
the rear wheel.
6. Full charge
endurance of the electric bicycle battery is directly related to factors such
as road, load, wind direction, temperature, bicycle condition (brake and tyre
pressure etc) and the control mode of the cyclist. It is necessary to use feet
to boost when riding a slope, bearing load and riding against the wind, so as
to avoid heavy load discharge of the battery and damages to electrical
equipment.
7. When the
battery is being charged, continue to charge for 1—2 hours after the indicator light changes
to green to make it fully charged.
8. Never
connect the no-load charger with the AC power so as to avoid thermal distress
of the charger.
9. When the
charger is used to charge the battery, never put anything on it, otherwise, it
will heat up and cause a fire.
10. When the
power of the battery is used up, instantly charge it, otherwise, its service
life may be greatly shorten. (When the power of the electric bicycle is low, it
may become start-and-stop, like cutoff and fuel cut-off when riding a motor
bicycle.)
11. Plug the
charger plug into the three-hole socket when charging the battery, so as to
avoid damages to the charger and the battery.
12. The charger
shall be used indoor, excessive vibration may affect the service life of the
charger.
13. When having
ridden the bicycle for half a year, check the front wheel, shaft and gear etc,
check whether there are abnormal abrasion or interference, whether the
lubricating grease hardens or reduces. Some manufacturers use inferior
lubricating grease to reduce costs, and this kind of grease will harden in
winter and lose its due functions, which may wear relevant accessories prematurely
and affect riding safety, or even result in burn fatality of the shaft and gear
and dangers.
14. Check
whether the wire rope, wheels and brake mechanism etc interfere each other or
not, instantly deal with the hidden dangers, if any, so as to avoid riding
dangers.
15. Regularly
check whether the wire rope of the brake is cracked and broken, and instantly
replace it. The broken wire rope is easy to water, which may cause the wire
rope rusts and breaks later, loses its due functions and runs into some
dangers.
16. The
rear-wheel motor shall not be disassembled and coated with the grease without
permission.
17. The
obsolete battery shall not be discarded at will, and shall be sent to recycling
department according to national regulations.
18. The
electric bicycle shall be maintained by professional after-sales maintenance
department.
Routine Inspection
1)
When adjusting the height of the handle, do not make the riser safety line out
of the front fork lock net.
2) When
adjusting the height of the saddle, do not make the saddle tube safety line out
of the frame central tube.
3) The front
and rear brakes shall be flexible and reset quickly with the help of the elasticity
of the spring, when the brake is fastened, between the brake handle and the
handle grip one-finger distance shall be left, and the brake rubber on both
sides and the rim parts that are controlled by the brake shall be parallel, and
up and down, right and left deviation shall be the same.
4) Check
whether the brake power break device is OK, erect the support, open the
electric switch, start the motor, then lightly hold the left brake handle; the
motor shall be powered off instantly, and gradually stop running. If the motor
cannot be powered off, stop running and ask professionals to make maintenance before
further application.
5) When the air
is inflated to a certain air pressure, rotate the rim and use hands to evenly
knock the tyre, then continue to inflate until the tyre and the rim coincide to
avoid skidding during ridding.
6) The
recommended torque of horizontal tube, vertical tube, saddle, saddle tube and
front wheel is 18Nm, and the recommended torque of the rear wheel is 30Nm.
7) Before
riding, check whether the electric equipment plug and polarity socket of the
battery box are loose, whether the electric door lock is flexible, whether the
battery box is locked well, whether the horn and the light button are effective
and whether the bulb is OK.
8) The height adjustment of the
saddle of the electric bicycle shall be subject to the landing of the feet of the
cyclist in order to ensure safety.
9) The design
load of the electric bicycle is 75kg, so, except the weight of the cyclist, try
not to bear too heavy objects, and boost with the pedals when bearing loads.
10) To ensure
safety, please open the electric switch of the electric bicycle when getting on
the bicycle and timely close the electric switch when stopping or pushing the
bicycle, in order to avoid accidents by sudden starting of the bicycle because
unintentionally rotating the handle.
11) Boost with
pedals when riding up a slope.
12) Never use
the motor starting handle and brake handle at the same time, for fear of
damages to other parts because of overload of the motor.
13) The
electric bicycle is not adaptable to uneven or steep road, excessive vibration
may result in poor connection of the electric equipment, please try best to
reduce the speed or get off to push the bicycle, in case of this kind of road
condition.
14) In winter,
because the low temperature lowers the battery capacity, the discharge depth of
the same ridding distance will be deepened; boosting with pedals will help to
extend the service life of the battery.
