CiA® 454 series: CANopen application profile for energy management systems
CiA 454 specifies the CANopen-based communication for a DC power line (PL) system, which is controlled by a CAN network. All energy sinks and energy sources connected to the energy management system (EMS) are accessed and monitored by the EMS controller (EBC). If required, the energy inputs and outputs of the devices are adjusted by the EBC to match the current conditions of the managed DC system. This ensures the operation of all devices connected to the EMS. Therefore, the operation of energy sources (e.g., batteries based on different chemistries) connected to the CANopen network is possible.
The EMS is primarily intended for light electric vehicles (LEVs), but it is not limited to these kinds of 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 comprehensive energy management. Therefore, this specification introduces a DC power line that is controlled via a CANopen network.
The battery (B) provides energy to the motor (MC). The EBC not only provides valid set points to the motor but is also responsible for the energy management; for example, in the case of extending the application by plugging an external charger (voltage converter, VC) into the LEV. Displays (HMI) and biometric sensors (S) can also be powered via the EMS and offer the LEV driver enhanced functionality.
An EMS can also be used in off-grid applications, such as isolated farms or recreational vehicles. The solar cells produce power, which is supplied to the DC- or AC-coupled consumers (loads, L) via the voltage converters (VC). If the solar cells are not able to produce sufficient power, a generator (G) can support the infrastructure with additional power. Surplus power can be stored in the batteries (B). As the devices are interconnected via CANopen, a single host controller can optimize the energy management (e.g., determining which energy source or load should 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 CANopen-based control network of the EMS approach realizes this management.
