CiA® 418: CANopen device profile for battery modules

The CiA 418 device profile specifies the interface for battery modules, to achive interoperability with battery chargers, e.g. implemented according to CiA 419, the device profile for battery chargers. A battery module provides information to a battery charger, which enables it to carry out a battery charge. The smallest amount of information is the battery type, battery capacity, number of cells, maximum charge current permissible, and the battery temperature. Additionally, optional information is defined, e.g. various identifiers, charge history data, battery voltage, battery state of charge, requested current and water level status. A default TPDO is defined to send the battery temperature and status information on a timer-driven basis. Optional TPDOs are defined for transmitting battery voltage, current requests and state of charge. A default RPDO is defined to receive charger status. An optional RPDO adds the "Charge Returned" object to the data received. Optional PDOs supported by the module can be configured via SDO services. The corresponding default PDOs are implemented in the battery charger. The battery module has to support the heartbeat protocol.

CiA 418 version 1.2.0 CANopen device profile for battery modules
Scope

This device profile specifies a recommended practice for the communication link between a battery module and a battery charger. The required data messages are intended to be sufficient to allow a battery charge to be carried out. Optional data is a selection of data commonly used in the industry to provide enhanced features. Battery modules compliant to this standard shall use communication techniques, which conforms to those described in the CANopen application layer and communication profile.

CiA 419 version 1.2.0 CANopen device profile for battery chargers
Scope

This device profile specifies the battery charger communication and application objects in order to obtain sufficient information from the battery module to allow a charge to be carried out. Optional data is a selection of data commonly used in the industry to provide enhanced features. Chargers compliant to this standard shall use communication techniques, which conforms to those described in the CANopen application layer and communication profile.
