@sturla Hello. Thanks for the reply, makes sense -- holding the SOC when desired. The next release of WS500 firmware (2.5.2.) is in fianl QA and we can not make any changes, but wil...
Hello, sorry for the delay. What is happening here is as the WS500 is running in Slave Mode it it following the directions of the REC BMS. As such, there is no 'Float' to force to ... ...
@Nathaniel CPF vs CPB, lol .. no worries! Yes, when the WS500 is in 'Slave' mode, all the CPx values are ignored, except those of CPB. You can set the CPB values to ...
Disclaimer -- Al from Wakespeed. What fun! OK, to step back a bit: When it comes to temperature of the battery there are perhaps two details to keep in mind:1) Battery Temp may be...
Hello. <Disclaimer: Al with Wakespeed> In 2.5.0 we indeed 'tightened things up' in support of some higher power 48v systems, but seems might have gotten things a little too tigh...
@Trond <DISCLAIMER: Al of Wakespeed> Hello. As Ben pointed out, FLT 43 is indicating the WS500 has not sensed voltage on the solid RED wire, the one with the 15A fuse in i...
<DISCLAIMER: Al of Wakespeed> Alan, You can use the DIPs to set basic configs for the WS500 -- works fine, but a bit rough granularity around the battery, and also no ability to adjus...
@Brent (Disclaimer: Al of Wakespeed). As suggested by Michael, it sounds like the float voltage needs to be adjusted. But am a bit more concerned by: "I have ...
Hello. (Disclamer: Al of Wakespeed). I am not an expert here, but I think you might (guessing here) be seeing some odd things on the main Cerbo screen, as from waht I understand the Ce...
Quote from Jonny Sollid on March 2, 2023, 11:31 am I have an installation with WS, REC bms and Cerbo that works quite well. But there are two challenges I cannot solve. When WS is in slave mode (R...
Quote from Sailor1313 on February 15, 2023, 10:28 am I have also been in contract with DragonFly about getting the 12v WakeSpeed work on the 12v alternator and have been very upset with their resp...
Wonderful, glad to hear. That is how it is intended to work. Nice and Simple. -al-
Hello all, Yes, some teething issues! Perhaps to be expected, and including the refreshed Wakespeed.com website this past week. As to Firmware and Drivers, I might suggest downloading the Wa...
Trond Arvid, That is such great news to hear -- we can do only so much \'in the lab\' even with live test benches, to hear your comment from actual field install is really nice. Thank you (I am...
Gregory, Hello. I have reached out to support to have then follow up to your question. Please be looking for that and sorry for the delay. (In short, all the phases are documented in the WS50...
All, Wakespeed WS500 ver 2.5.0 was released Monday -- but it might take a bit to get posted to the website. For all\'s convenience, I have attached the .dfu file and the companion con...
Wakespeed firmware 2.5.0 is being released this week; and has some improvements - but there still might be work needed on the REC side for its requests, as well as refinements how the REC BMS is co...
We are indeed looking at current stability, esp with CAN based instrumentation and BMS \'moving targets\' in a rather quick fashion (Blue line in your graph). Most BMS\'s assume quick responding M...
REC has informed us a new REC BMS Firmware will be sent to us this next week for testing. We (Wakespeed) will be looking at this behavior as well as other noted issues around REC. The...
Eric, For your install I would refer you to the Victron Lynx website - it has a few very extensive examples of how to install the Lynx BMS with dual alternators and the WS500. In or...
A quick follow up, we have verified this behaviors with one of our Beta testers and I have an Email out to REC -- REC and Wakespeed to work to improve the EOC handling. And noting als...
Not Neil, but will give some ideas... CAN has three different wiring \'topologies\' that Wakespeed commonly supports: RJ45 (With a variety of different pin-outs) DeviceNet (aka: NMEA-20...
I have seen this before while working with BMS manufactures in proofing reliable Alternator based charging systems; the \'Twitchiness\' I call it seems not much of an issue with pure electronic cha...
Appreciate the feedback; at issue I think is the wide use of N2K and how it works on a wide range is displays. Because some PGNs are reused for a lot of different sources (Battery, Alt, etc), we h...
We do have some hidden hardware feature to exploit in future firmware leases; a prime focus for 2021 has been expanding the know well supported battery systems, and focus on features to assist inst...
\"Is this reserved for future HW versions?\" Yes. <smile> We have many deployments with two large frame alternators (ala, 24v / 280A large frame Leece Neville alts) and no issues. The d...
ARG -- NMEA and details... As you found, the WS500 is able to send \'NMEA2000\' like messages via CAN, and uses 127508 as a way to send out some otherwise unavailable details for the alternator,...
Hello. Sorry for the delay in posting this note: The 15 second is a min time needed; during startup the WS500 monitors the CAN bus looking for other devices on the same battery; as well as if t...
Hello, I do not believe the scale dynamically adjusts - and is fixed for both 12v and 24v deployment. The Color bands seem to be the same situation.
Blaine, Hello. Rick asked me to chime in: You are correct. What happens is the REC BMS will send charge needs and directions out via CAN which both the WS500 and Victron\'s CCGX receive. Th...
As Rick said, there are indeed two DB-9 connectors on the REC ABMS: one for Serial access via RS485 for configuration and such, the other for CAN. To connect the WS500 just connect up the CAN-H a...
We are targeting v2.2.0 firmware to be released some time in Feb, likely mid Feb. Am in the final phases of testing now. It will have the changes talked about above: -- Min/Max bat temp limits...
Andy, Hello. Sorry you are having issues. Reading your description, it sounds like one of the regulators is loosing its configuration - restoring to the factory default state? Is t...
Hello, Fault states are not retained by power cycling, and in fact power cycling is the only way to clear a number of hard faults. Of course, once power cycled if the condition still existing ...
I would say for your application, either an overdrive 12v alternator (with care about the diodes) or a standard 24v alternator would work. Much depends on how you are driving it, and the expectati...
Not sure about the other way, never seen a need where someone did that. On reliability, perhaps overthinking a bit. As long as one does not overheat an alternator, the likely failures are then ...
Glad could help. And yes, the Ws500 does have a lot of capability - most of the time we have an answer for problems folks are having. And on the rare occasions when we don\'t, we can look to incl...
Cold hard stop: Ya, plus there are some batteries with heaters in them that we support, allows very cold operations! Plus, batteries getting too cold are not commonly a result of the alternator ...
You are welcome. Breaking this down: \"So in normal operation if LIMIT_FLOAT_AMPS=1, the alternator will provide a 1 Amp current to the battery so long as Vbat < Vfloat?\" Yes, you are corr...
High Rick, Yes - a question we get a bit. So, there are perhaps two flavors of this: Two alternators on the same engine. Two engines, each with an alternator. For the 1st ...
