Safiery CANbus Alternator Controller

CAN (C ONTROL A REA N ETWORK ) C OMMUNICATIONS The WS500 Alternator Regulator features CAN (Control Area Network) ports. Developed in the 1980’s by Bosch and targeted towards the transportation sector, CAN is now one of the most widely deployed communications standards covering not only the Transportation sector but also used in Industrial, Heavy Industry, Farming, Medical, Consumer, and more. Over a billon CAN nodes have been deployed, with modern automobiles contained upwards of 100+ individual nodes each! It is a proven reliable and robust communications standard with many feature to assure deterministic and prioritized communication resulting in a solid and proven reliable communications backbone. Utilizing CAN devices are able to integrate into a ‘System’ where each works in cooperation with the others. Further, the CAN allow simple and reliable way to connect computers or displays for ongoing monitoring and easy configuration. The WS500 Alternator Regulator utilizes standards covering physical wiring, message content and other communications standards. These include:

CAN Specification 2.0b / ISO-IS 11898



CiA 303



SAE J1939



 OSEnergy (Open Systems Energy - derived from the RV-C standard)

OSEnergy (Open Systems Energy) is an architectural specification who's aim is to provide a framework for the design, deployment, and operation of charging sources associated with a DC battery. Allowing them to work together in a 'systems' approach while meeting the full requirements of an associated battery as well as concurrently supplying house power needs in a consistent and efficient way.

Through the application of these standards the WS500 Alternator Regulator is able deliver several key benefits, including:

 Coordination of charging goals and objectives; all devices work towards the SAME goal vs. fighting each other.  Tight BMS integration. CAN communications allows for the WS500 Alternator Regulator to fully integrate with the needs and directions of a BMS at levels unattainable using simple ‘Charge Enable’ wires.  Prioritization of charging sources, e.g.: Utilization of Solar to its maximum capability while filling in the remaining energy needs from an engine driven alternator - thereby saving fuel.  Remote sensing / Port Expander: The WS500 Alternator Regulator is able to take advantage of the CAN communications capability to transfer real-time battery status: voltage, amperage, and temperature as well as operational status (e.g., off-line in the case of a LiFeP04). By using this capability wiring and installations may be simplified.  Self healing / fail over: Ability to self-recover from a failed, removed, or turned off device. The system continuously monitors all devices and adjusts as needed.  ‘Get - Home’ total system failure mode: In the event of a catastrophic total system communications failures, the WS500 Alternator Regulator will fail-to-safe and operate in a stand-alone mode. Allowing for continued charging, but perhaps with less optimization and longer times needed.
