CiA® 419: CANopen device profile for battery chargers

(Source: Adobe Stock)

The CiA 419 device profile specifies the CANopen CC (classic) interface for battery chargers, to achieve interoperability with battery modules, e.g. implemented according to the CiA 418 CANopen device profile for battery modules. In minimum, a battery charger needs the information about the battery type, battery capacity, number of cells, maximum charge current permissible, and the battery temperature, to execute a charging procedure. Most of this information is specified in the CiA 418. Additional, optional data is specified for further enhancements.

A default RPDO (receive process data object) is specified to receive the battery temperature and status information on a timer-driven basis. Optional RPDOs are specified for receiving the battery voltage, current requests, and state of charge. A default TPDO (transmit PDO) is specified to transmit the status of the charger. A further optional TPDO enables to transmit the "charge returned” object indicating the number of Ampere-hours delivered to the battery by the charger during the last charge event. The battery charger has to provide a connector corresponding to the chosen battery module. Support of the NMT (network management) server and heartbeat functionality according to CiA 301 is mandatory for the battery charger.

CiA 301 version 4.2.0 CANopen application layer and communication profile
Scope

This specification specifies the CANopen application layer. This includes the data types, encoding rules and object dictionary objects as well as the CANopen communication services and protocols. In addition, this specification specifies the CANopen network management services and protocols. This specification specifies the CANopen communication profile, e.g. the physical layer, the pre- defined communication object identifier connection set, and the content of the Emergency, Time- stamp, and Sync communication objects.

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.
