Regulators disable or ‘Zero Output Technology’ options may be selected to adjust how the WS500 behaves when the BMS request no additional battery charging. . The LYNX BMS will also issues a proper warning before disconnects, assuring safe shutting down of the alternator.
Lithium Werks**: Support for the Lithium Work BMS is provided via a proprietary CAN communications protocol. When enabled, this protocol will allow for the Lithium Werks BMS to send charge goals and limits (Voltage and current) to the WS500 Alternator Regulator. Battery current and Temperature are also provided as well as BMS warning and alarming states. Both normal and Zero-output technology is supported, and the communications protocol may allow for stable active current regulation using the Remote shunt, however if instability is noted a physical shunt may need to be installed. The Lithium Werks BMS does not provide a 2-seconds advanced notice of impending disconnect, as such some level of mitigation steps will need to be put into place in the overall system design.
LUX: The LUX protocol is a slight variant of the SAM protocol. Also an 11-bit message, it is common in China sourced BMS’s. As with the SMA handling, LUX 11- bit CAN messages will be ‘converted’ into an OSEnergy type device with a fixed CAN-ID of 69 and a priority of 120. Aggregation is not supported. The following CAN messages are utilized. (Refer to your BMS guide for details of these messages)
0x351: Battery Charge Voltage, Charge Current Limitation 0x356: Battery Current, Battery Temperature 0x359: Alarm/Warning 0x35C: Charge Enable Bit
Details for message 0x351 and 0x356 are the same as with SMA, detail for message 0x359 is the same as the SMA 0x35A. Message 0x35C includes byte-0, bit 8 to incident if charging is allowed. It (along with a goal current of 0A in message 0x351) will be used to direct the WS500.
**Note: As of June 2021, these protocols have not been proofed in the field. Contact support@wakepseed.com to enquire about the latest status.
