I just picked up a charger that does 120V and 220V but not sure which relay to use for this varying AC voltage.Lance Johnsonhttps://www.blogger.com/profile/16423026657246655049noreply@blogger.comtag:blogger.com,1999:blog-1291159839630780961.post-52173258450654555682009-05-23T15:15:39.383-04:002009-05-23T15:15:39.383-04:00Have you figured out how to wire the A/C 220v and ...Have you figured out how to wire the A/C 220v and the 110v for the charger.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1291159839630780961.post-90912671596406490142009-05-12T12:19:00.000-04:002009-05-12T12:19:00.000-04:00The decision to set 3.8V as the max voltage was my...The decision to set 3.8V as the max voltage was my decision. I have been speaking with fellow EV converters and we believe that 4.2V is the peak before damage can occur. We feel that going to 4.2 is too risky. The charger vendors will ask you how you want these values to be set or will simply set them based on the data provided for your cells. So, in my case, I provided the values of 3.8 (for max) and 3.6 (for charge to). This does not mean that your higher values are no good. It's just an opinion I guess. Others out there are much more knowledgable than me in this area so I just went the safe route and hopefully the right route.<br /><br />JimJimhttps://www.blogger.com/profile/06598196210896738598noreply@blogger.comtag:blogger.com,1999:blog-1291159839630780961.post-12266860818812564362009-05-11T18:17:00.000-04:002009-05-11T18:17:00.000-04:00Nice progress!

Was there any reason to choose lower max voltage which might cause cells not to charge fully? Who is more right, Thundersky or guys selling the charger?Mindaugas Milasauskashttps://www.blogger.com/profile/06016474949287302548noreply@blogger.comtag:blogger.com,1999:blog-1291159839630780961.post-1504728955368454142009-05-10T22:17:00.000-04:002009-05-10T22:17:00.000-04:00Looking good, Jim.

This can be the source for the KSI input of the controller, which requires "pack +". (Double-check the Curtis manual, but that's basically what I do for my Logisystems/Delta-Q setup).<br /><br />By the way, I just ran into trouble with the SAAQ... make sure your GVW is well below (GVWR-70kg*NumberOfOccupants) and GAW's are respected (center of mass).<br /><br />They were rather unenthusiastic regarding my suspension modifications; and you'll want to get a clear statement on requirements for "modified vehicles" which are equipped with airbags.<br /><br />At the very least, I will need an (OIQ-registered vehicle mechanics and dynamics) engineer to sign off on everything. At worst, I have to undo the suspension mods and return the car to stock weight; in which case I will have to sell the vehicle. <br /><br />Contact me via email and we can discuss. Things should become clear this week.<br /><br />Cheers,<br /><br />-NickNick Drouinhttps://www.blogger.com/profile/05359522740426365830noreply@blogger.comtag:blogger.com,1999:blog-1291159839630780961.post-66883535052813299382009-05-09T11:23:00.000-04:002009-05-09T11:23:00.000-04:00Coming along nicely Jim.
