WindRunner™ self-balancing electric vehicle user’s manual

1. Introduction of WindRunner™

1.1 How do a WindRunner work?

The WindRunner™ is a dual-wheel self-balanceable electrically operated vehicle, a revolutionary

ride-instead-of-walk and recreational tool. The driver may operate the movement of

WindRunner by standing on it, and shifting his/her body. The WindRunner itself may

automatically keep balance and the driver does not have to worry about the risk of falling.

With the built-in electronic gyro, the on-board high speed CPU may calculate in 200 times/s

whether the mainframe of WindRunner is balanced forward and backward or not. If not, the CPU

may control the motor on both left and right sides to rotate rapidly, and keep the WindRunner

balanced. The self-balancing function, allows the driver to stand on the WindRunner with his

body inclined forward. The mainframe may automatically enable its wheels to move forward,

and the WindRunner will move forward; and vice versa. Simply turn the handle left and right.

Because the balance of WindRunner ™ completely depends on the good functioning of a high

speed CPU, precision gyro, and motor, if any one of them has troubles, the WindRunner may

lose balance. The WindRunner ™ has a hot back-up dual-redundant control system which

ensures that all key circuit systems shall be doubled. Therefore, if any one of the key modules

fails to work, the backup may be put into operation so as to maximize the safe riding.

While in beginner mode, press the “Speed limit” button on the intelligent remote key. You may

hear a very short buzz or “tick”, and the red LED at the lowest part of display panel will change

into blue and glow steadily. This means that the Speed limit mode is entered. Under this

operating mode, the maximum speed of WindRunner is between beginner mode and balance

mode for complicated road conditions.

3.2.3 Normal mode- 20km/h max

The normal mode is another balance mode, suitable for experienced drivers on good road

conditions (e.g., no pedestrian and even path). This mode may be applicable for riding

WindRunner. Under the Speed limit mode, press the “Speed limit” button on the intelligent

remote key. You may hear a very short buzz or “tick”, and the blue LED at the lowest part of

display panel will cut off. This means that the normal mode is entered. Under this normal mode,

9. Troubles and alarms

9.1 FAQs and troubleshooting

1, Unable to power on:

 Please verify whether the battery of intelligent remote key has sufficient capacity, or retest

the power after the battery is replaced. If powered on only when the intelligent remote key

is quite close to mainframe, it means that the battery of the intelligent remote key has been

approximately used up and you are now required to replace the battery. (consult 4.5 of this

manual)

 If the battery of the intelligent remote key has enough battery capacity but is still unable to

power on, then it may be caused by the power of the WindRunner battery being fully used up.

It may also refer to an internal circuit failure. Please retest only after the WindRunner is fully

charged. If still unable to power on after it has been fully charged (refer to 7.2 of this

manual), please contact the local agent/distributor for repair.

 During normal riding, if the WindRunner is unable to power on after automatically being

powered off, or if there is a high resistance felt during traction of WindRunner, then it is

probably caused by internal motor riding circuit failure. To prevent short-circuiting of the

WindRunner™ self-balancing electric vehicle user’s manual

79

battery, the user should remove both batteries as soon as possible. Do not hesitate to

contact the factory for repair.

2, After powered on, alarm or red LED continuously flickered:

 If able to power on, but you hear the alarm only after powered on, this means that the

WindRunner has not passed the power on self-test power on self-test. The detailed trouble

information is related to LED state, so please consult the 9.2 alarm information code list to

verify the problem and solving method. For troubles you are unable to solve by yourself,

please contact the local agent/distributor for repair.

3, Once powered on normally, and after the driver gets on; if there is no

turning of the handle, the WindRunner itself shall rotate or face-up and

down while making a turn at site:

 This situation is usually caused by a great change of ambient temperature. You can

compensate for the change in temperature by taking special steps with the WindRunner

intelligent remote key. The detailed steps are as followed:

 First power on. After powered on, press the “lock” button on the intelligent remote

key. The WindRunner will enter lock mode. Then press the battery capacity display

button four times. At this moment, the blue LEDs on the display panel shall come on

in turn from lower to upper. A LED shall come on each time you press this button.

WindRunner™ self-balancing electric vehicle user’s manual

80

Once all four LEDs come on, the WindRunner will automatically enter into the

temperature compensation calculating progress. This calculating progress will last for

about 3s. During this process, please ensure that the WindRunner is in absolute rest

condition.

 After 3s, all blue LEDs will cut off. Then the temperature compensation will end. You

may now continue with the normal riding.

 If there is still a problem after the temperature compensation has ended, please

repeat the compensation steps mentioned above.

4, During normal riding, sudden alarms, Speed limits, and accompanying

acute shaking:

 The intelligent safety alarm system may be activated, or the internal safety system test may

have found hardware trouble (including one of the hot back-up systems failed). This is

usually caused by too high temperature, a heavy load, unsafe riding methods, or hardware

failure detected while riding the WindRunner. Please consult 9.2 trouble code lists for details

of troubles. If unable to solve by yourself, please contact the local agent/distributor for

repair.

9.2 List of alarm information codes

WindRunner™ self-balancing electric vehicle user’s manual

81

If any troubles arise (or intelligent safety alarm is activated), the lamps on WindRunner shall

continuously flicker. This will be accompanied with alarm sound, and an acute shake in the

mainframe. While riding, if any troubles arise or intelligent safety alarm is activated, the

WindRunner will forcibly decelerate, and you will experience an acute shake in the mainframe.

Warn the driver to get off. If it is an irreversible trouble, the WindRunner shall power off

automatically if alarm goes off for 20s.

Preliminarily determine the causes of trouble or alarm according to the flicker of LED at the

Appendix B. Deep understanding WindRunner

B.1 Battery stamina and battery indication

Factors affecting the battery stamina

For the same set of batteries under different service conditions, after charged, its stamina may

be quite different. The followings are some factors affecting the stamina:

 Try to ride under uniform speed (12～18km/h) to prolong the stamina of the battery once

charged. Frequently accelerate and decelerate. Low-speed riding and maximum speed riding

may shorten the stamina of the battery once charged.

 Riding at 10

℃

～30℃

may get the maximum stamina for the chemical properties of the

lithium battery. Riding under low temperature or high temperature may decrease the

optimum stamina.

 The nominal mileage of the WindRunner battery is determined under the carrying capacity of

70kg (including the driver and luggage). The higher the weight of the driver, the lower the

stamina of battery. On the contrary, the lower the weight of the driver, the longer the

stamina of the battery.

WindRunner™ self-balancing electric vehicle user’s manual

94

 An uphill slope may quickly shorten the stamina of a battery, but a downhill slope may

prolong the stamina of a battery. Under extreme conditions, a gentle slope of a continuous

several kilometers may charge quite a great amount of the battery capacity.

 Rugged and uneven road surface may shorten the stamina of a battery, but a flat and

smooth road surface may prolong the stamina of a battery.

 Check the tire pressure of the WindRunner. Usually the tire of the WindRunner G1U urban

type is 10

～

20PSI, and that of all terrain type G1X 4～8PSI. The higher the tire pressure, the

lower the friction resistance. Thus prolong the stamina of battery, lower the tire pressure,

and lessen the stamina of battery—but it may be comfortable on a rugged and uneven path.

Accuracy of battery indication

 The WindRunner has five LEDs for indicating the battery capacity. Though, these are a rough

means for indicating the capacity of the battery.

 Because the power required for riding the WindRunner varies greatly (for example, only

about 300W required for uniform motion on flat and smooth road surface, but accelerate on

a steep slope may require 2000W), it is difficult to have an accurate indication of the battery

capacity. The user shall try to avoid acute acceleration with battery capacity less than 40%

or moving on a complicated land form. Try to avoid moving uphill for long periods at a time.

WindRunner™ self-balancing electric vehicle user’s manual

95

 The properties of a battery may vary gradually with frequent use. So the battery indication

may be inaccurate after a period of time. To ensure high safety, the battery capacity of

WindRunner has a redundant safety margin. When the battery indication has only one

division, the WindRunner begins its Speed limit and shake alarm. The battery is actually

10%

～

30% left. For safety reasons, also keep an eye out for battery discharge. If you do all

of these things, the life cycle of the battery may be prolonged.

B.2 Tire and land form

 The tire pattern and land form have an adaptability and compatibility relationship. Moreover,

the performances of the tire used for suitable or unsuitable land forms vary greatly.

 The tire of the WindRunner G1U urban type is suitable for common urban road conditions

such as asphalt road, cement road, glazed tile and brick road, rigid leveled earthy roads, etc.

Under these service conditions, G1U urban type may award the best riding experiences, and

optimum tire adherence effect, and optimum battery stamina. But the all terrain type is

lower efficiency on urban road, so the battery stamina is relatively lower, and the tire may be

worn more rapidly.

 The pattern of tire for the WindRunner G1U all terrain type is applicable for grassland, earthy

slope, forest land, and muddy/rugged mountainous road. On these road situations, G1X all

terrain type may reach its optimum shock-absorbing effect, and optimum tire adherence

WindRunner™ self-balancing electric vehicle user’s manual

96

effect. Although G1U urban type may be also rode on some rugged and uneven road with

difficulty, its tires will have poor adherence, lower safety and shock-absorbing effect than

that of all terrain type tire. So more caution should be considered when riding.

B.3 About intelligent Speed limit

 The WindRunner has adopted the battery capacity based intelligent Speed limit algorithm.

According to different battery conditions (cycle times/ battery ageing, residual battery

capacity), the internal processor of the WindRunner may automatically determine the

maximum Speed limit value.

 In good conditions, if the battery capacity is >60%, the WindRunner may continuously ride

under balance mode- normal mode in a speed slightly higher than 20km/h.

 In good conditions, if the battery capacity is <60%, the maximum Speed limit of the

WindRunner may be reduced gradually with the reducing of battery capacity.

 If the capacity of any one of both batteries is <10%, the WindRunner shall give a low-voltage

alarm buzz, mainframe shake, and the foot mat will face-up greatly to warn the driver to get

off and charge as soon as possible. Under these situations, it is unsafe to continue riding.

WindRunner™ self-balancing electric vehicle user’s manual

97

 If the ambient temperature is detected to be to low(<-10 ) or too high (>40 ) at the

℃ ℃

moment the WindRunner is powered on, the intelligent Speed limit of the WindRunner shall

also function. Just then, even if the battery capacity is full, the maximum speed may be

unable to reach. To ensure high safety, the detailed Speed limit depends on the

WindRunner’s internal intelligent Speed limit algorithm.

B.4 Hot back-up safety mechanism

 Several key components of the WindRunner have the hot back-up safety mechanism to

maximize the guarantee of the driver’s safety.

 Hot back-up battery pack: both battery packs are used together, one for operating, and one

for standby. If one battery pack fails, powers off, or disengaged, it may not cause accidents.

Reason being, the WindRunner may immediately detect the exceptions of the battery pack,

and decelerate immediately. The shaking mainframe will give the alarm buzz and warn the

driver to get off.

 Hot back-up posture sensor unit: the posture sensor unit is the core of the WindRunner. If

the posture sensor unit fails and does not work while riding, a serious accident may be

possibly happen. To ensure safety, two sets of individual posture sensor units are provided.

Through a unique control algorithm, if any one sets out of function, the system may avoid

WindRunner™ self-balancing electric vehicle user’s manual

98

serious accidents such as over turn, etc. The WindRunner will immediately decelerate. The

mainframe will shake give an alarm buzz, and warn the driver to get off.

 Hot back-up power subsystem: the WindRunner has a great amount of built-in

micro-electronic devices, which require the converter for power supply. The micro-electronic

chip (IC) has very low failure rate. However, if partial power fails, the system will power off.

Then all the hot back-up design shall lose its significance. So two sets of power supplies were

provided. Any one set may be sufficient for support of the whole system individually. If one

set of the power supply system fails, the system may immediately detect trouble, and

immediately decelerate. The mainframe will shake, give an alarm buzz, and warn the driver

to get off.

 It should be noted that the hot back-up technology can’t give the guarantee of 100% safety.

For example, both gearbox and tire are unable to provide the hot back-up. The hot back-up

design may only try to improve the safety of the WindRunner. This is neither a guarantee for

free troubles such as tire burst, nor a guarantee for skidding of tire. Strictly obey chapter VI
