2.3 Handling of Wheel Units
The Wheel Units are equipped with a built-in, high-
performance battery with a capacity of 6.5 Ah.

2.3.2 Storing the Wheel Units
Self discharge
temperature of 20 °C is less than 5 %, with a charge level
between 15 and 50 %.
Storage temperature
The recommended storage temperature is between 15 °C
and 30 °C without direct sunlight in a dry, clean, well-
ventilated place.
KiRoad Wireless HDR, Type 9813C... and Type 9822A...
9813C_002-952e-10.23Page 8
Storage outside of these temperatures can lead to a
greater amount of self discharge, lower performance and
swelling of the battery cells.
Minimum charge level during storage
A minimum charge level of 3.62 V at the end of storage is
necessary to prevent deep discharge.
the battery!
If the battery voltage is low or even 0 V after storage, the
battery must be charged as quickly as possible to avoid
the voltage of one or more cells falling below a level
where the cell can be damaged.
To do this, "wake up" the battery by connecting the
supplied charging device.
When the battery receives no charge, it is likely that the
voltage in one or more cells has fallen below the voltage
level below which it is prohibited from accepting a charge
for safety reasons. Because of this, the electronic protec-
tion circuit is activated and inhibits further charging.
If the battery is to be stored for more than 3 months to
less than one year, proceed as follows:
Regular monitoring of the battery voltage, at least
once every 6 months
If necessary: Charge the battery up to 50 % of its
capacitance
Important notes
Page 99813C_002-952e-10.23
2.3.3 Using the Wheel Units after a long storage period
After a long storage period, the following procedure is rec-
ommended:
Complete discharging of the battery
Preferably, run a complete charge / discharge cycle.
Otherwise, it may take 2 to 3 cycles until the maximum
capacitance is available again
Completely charge the battery
2.3.4 Safety information
Do not dismantle the battery
Do not short circuit it
Do not drop or hit it forcibly
Only charge it with the original charging device
2.3.5 Transporting the Wheel Units
Legal conditions
Due to the lithium ion battery installed, the wheel units
must be shipped as hazardous materials. The UN number
UN 3481 applies.
Units for transport must satisfy all of the requirements,
including, but not limited to, special requirements, pack-
aging regulations, labeling and training.
Overview
Individuals who prepare Wheel Units for transport must
specify the applicable measures and instructions care-
fully. Additional information on this can be found in the

3. Product description
3.1 Overview
The KiRoad Wireless HDR On-board Unit serves as
access point for up to four KiRoad Wireless HDR
Wheel Units, Type 9822A..., and enables measure-
ment data to be output to the connected data acquisition
device. The connected RoaDyn wheel torque transduc-
ers automatically log on and identify themselves after the
-
tion is automatically read into the device so that the sys-
tem is quickly ready for operation without additional user
action. The signal is output to the data acquisition system
-
triggered using the remote control or via Ethernet or USB
from the laptop or PC using the KiCenter software.
The Wheel Unit including exchangeable accumulator bat-
tery, the rotary encoder for trecording the angle and the
Since each KiRoad Wireless HDR system sets up its
own encrypted WLAN network, several KiRoad Wireless
systems can operate simultaneously without interference,
e.g. several vehicles each equipped with 4 RoaDyn trans-
ducers.
If a Kistler DTI-Logger is used for data acquisition, only
one cable is required for the On-board Unit to transfer the
via KiCenter. Otherwise, the CAN signals and analog
friendly via KiCenter using Ethernet or USB. All transmit-
ted measurement data can be viewed in KiCenter.
