CiA® 454 series: CANopen application profile for energy management systems

CiA 454 specifies the CANopen-based communication in a system where the DC powerline is accompanied by a robust CAN system. All energy sinks and energy sources, connected to the energy management system, are accessed and checked by the Energy Management Controller (EBC). If required, the energy in and outputs of the devices are adjusted, by the EBC, to the current conditions at the managed DC system. This complements a safe operation of all devices connected to the energy management system. Therefore, the operation of energy sources (e.g. batteries based on different chemistries) in the same network is enabled as well.

EMS is primarily intended for light electric vehicles, but it is not limited to these kinds of applications. In these applications the availability of several energy sources (e.g. batteries, generators, etc.) as well as several energy sinks (motors, sensors, lights, displays, batteries, etc.) requires a comprehensive energy management. Therefore, this specification introduces a DC-powerline that is controlled via a CANopen network.

The battery (B) provides the energy to the motor (MC). The EMS controller (EBC) provides not only valid set points to the motor but is also responsible for the energy management; e.g. in case of lengthening the application by plugging an external charger (voltage converter, VC) to the light electric vehicle. Displays (HMI) and biometric sensors can be powered via the EMS as well, and offer the driver of the LEV enhanced functionality.

EMS can also be used in stationary off-grid applications such as isolated farms or recreation vehicles. The solar cells produce power, which is provided to the DC or AC-coupled consumers (Loads, L) via the voltage converters (VC). In case the solar cells are not able to produce sufficient power, a generator (G) can support the infrastructure with additional powers. Surpluses of power can be buffered in the batteries (B). As the devices are interconnected via CANopen, one host controller is able to optimize the energy management (e.g. which energy source or load shall be activated or disabled).

In this case the EMS is used to regulate the submission of self-produced energy to the public infrastructure. The solar cells produce the energy and the produced energy can be buffered in a battery, till the best moment (e.g. with regard to making profit) of submitting the energy to public infrastructure is reached. The accompanying CANopen-based control network of the EMS approach realizes this management.
