Wakespeed WS500 DVCC.

Venus OS V3.30-10 now has support for "Alternator controller integration".

  • Add DVCC support for the Wakespeed WS500.


Has anyone tested this or can explain what it does?

My setup is REC-BMS -> Cerbo GX -> WS500 -> NMEA2000.

So everything is on 250 kbps and using the VE-CAN port only.


Does this update mean I can move the REC-BMS over to the BMS-CAN port at 500 kbps, and the Cerbo will control/forward DVCC to WS500?

One or two benefits' from this would be to limit current and/or voltage from the DVCC menu in the Cerbo.

The Cerbo will not send stop charge commands between the VE CAN port and the BMS CAN port, so if the managed battery on the BMS CAN port issues a stop charge command, the Cerbo will not transmit this to the VE CAN Port which the WS 500 is on. Only use VE CAN and 25kbps for all your devices.

Such a configuration has not been tested. What has been tested is the CerboGX, BMS (Lynx Smart BMS) and Wakespeed all on 256Kb VE.Can port. It allows the Wakespeed to follow voltage and current as requested by the GX. Therefore the maximum battery charge current will be split across all DVCC controlled devices, including the Wakespeed. If the user modifies the maximum charge current or voltage in the DVCC menu then the Wakespeed will be sent those voltage limits or a portion of the current (depending on other DVCC devices such as Solar, Shore).

You will also require a beta/Alpha firmware for the wakespeed device.

Wakespeed FW 2.5.2 is coming imminently and will allow DVCC control of the Wakespeeds. I have tested it and it works beautifully.
Watch the Wakespeed website for the release.

Do you have a lynx or BMS v2? Curious as to your experience or settings. I have am working on the new update settings. Have a BMS V2 so the user above that answered with a non answer is not applicable.

I haven't tried with a VE Bus BMS, only with a Lynx BMS.
