    DS 418 V1.0.1 CANopen device profile for battery modules CiA 1 Scope This device profile describes 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 2008 – All rights reserved 5

    DS 418 V1.0.1 CANopen device profile for battery modules CiA 4 Operating principles 4.1 General The purpose of the battery module is to provide information to a charger sufficient to allow a charge to be carried out. The minimum information required is the battery type, battery capacity, number of cells, maximum charge current permissible, and the battery temperature. All devices conforming to this specification shall provide this information in the manner described. Additional, optional information, such as various identifiers, charge history data, battery voltage, battery state of charge, requested current and water level status are also defined. Conforming devices need not supply this information, but if they do, they shall provide it in the manner described herein. 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 charge returned to the data received. Battery parameter information may be read by SDO services. If the charger supports any of the optional data items, these may be read by SDO services. If the module supports the optional PDOs, then they can be configured via SDO services. The battery module shall support the heartbeat function, and may optionally be a time-stamp consumer. 4.2 Physical layer 4.2.1 Connector The battery module shall have a 5-wire interconnect. The communications bus shall use three of these lines (CAN_L, CAN_H, and ground), and two shall be used for the pilot signal (see appendix B). The actual connector used and its pin configuration will vary depending on the battery’s application, and thus is outside of the scope of this document. 4.2.2 CAN transceiver The CAN bus shall use standard high-speed differential transceivers compliant to /ISO11898-2/. The battery module shall support at least the 125 kbit/s default bit-rate. A termination resistor of 124 Ohm shall be included in the default battery module configuration. 8 © CiA 2008 - All rights reserved
