4.5.2 Batteries with CAN communication
Batteries with CAN communication have a battery management system (BMS). This
controls and monitors the charging and discharging processes of the battery in order to
use it as efficiently as possible. The BMS can provide the user/controller with a lot of
useful information.
This results in the following:
- If only one battery is used, it can be switched on and off via the control element, but
not all batteries support this function
- Through the CAN connection, the battery charge level determined by the BMS can
be accessed

4.6.1 Notes on EMC
• In DIN EN 15194:2018-11 two different measuring distances of 10 m or 3 m are
provided for measuring EMC. The permissible limit values differ for both measuring
distances. Experience shows that the results of the measurement for a distance of 3 m
are more advantageous.
• It is advantageous for EMC if all cable lengths are kept as short as necessary.
Excessively long cables or loops increase the risk of interference.
• Cables should not be laid in parallel if possible. Above all, motor and battery cables
must be routed as separately as possible from each other and absolutely separately
from signal cables in the vehicle.
• If problems occur during EMC testing, folding ferrites on the cables can usually
remedy the situation. By using them, it can be determined which cables are the cause
of the problems. Additional shielding or modified routing solves the problems in
most cases.
• In order to improve EMC, it has proven useful to choose an installation location for
the controller box that is as low as possible on the vehicle.
