CAN interface
Communication with the BMS is performed via the CAN bus. All the relevant data can be viewed. For
this see the CAN matrix which is provided in a separate document. Where a battery pack is connected in
parallel, we recommend a combination of terminal 15 and the CAN wake-up. This ensures that the CAN
and the BMS can communicate with each other and operate without problems.
3.4 Control
Central control system and
software
The control system for the superordinate machine is handled by the machine manufacturer. The machine
manufacturer must determine the operating modes for safe operation.
All required safety barriers, safety functions and safety controls must be put in place by the
superordinate machine’s manufacturer.
It remains the duty of the superordinate machine’s manufacturer to ensure that the product is
properly used in and approved for the overall system, the customer's environment and the target
market.
Make sure that the superordinate system/machine can perform the following functions and supplement
them in accordance with your own risk assessment:
■
The technical data specifications in the data sheets must be complied with.
■
Load circuit faults cannot trigger any hazard and can be safely rectied.
■
Load circuit power supply failure will not result in danger.
■
The battery does not feature integrated insulation monitoring (IMD). Should such be required for
safety engineering reasons or legally, insulation monitoring will need to be implemented in the
superordinate system.
■
Observe the technical requirements relating to the IP class, environmental conditions and impact on
EMC:
°
It must be possible to galvanically isolate the superordinate machine from the mains by means of a
main switch in order to enable work on live parts.
°
Install the device in a well-ventilated room that is not too small, to protect it from overheating.
°
Protect the device from moisture and dripping and splashing water.
■
It is impossible for people to reach into the electrical circuit’s danger zone.
