Re: Smokinjoe's Beetle conversion

[/image] Hi guys, Here's my 1970 Beetle I've been restoring for the last couple of years. In the last few months I've finished the panel and paint and now I'm starting on the fun stuff :) Mounted on the original transaxle is a Nissan leaf motor and inverter which will likely be controlled by an ope...

Re: Antiscab's NWH10 Prius plugin Lithium conversion

sadly my one uses an obscure communication language called OBD-M or multiplexed OBD, so man in the middle adjustments for me my main issue is how to the car from over charging, or overdischarging individual cells.

Re: Antiscab's NWH10 Prius plugin Lithium conversion

Sorry if this is dragging your thread off topic Matt, feel free to delete it or move it if you want. Looking further into Mathew's post, apparently the LTO cells can handle a lot more current in both directions that the lithium ferrous cells.... or have I got that wrong?

Re: jonescg's home battery storage system

Shitte, I'm glad I only do off grid solar/battery/inverter jobs, that all looks like a massive headache for very few $$ return from the grid. I do enjoy giving the grid supply the "bird" when they ask about certain items they consider are an essential, like the fire starters on the solar arrays .......

Re: Prelude conversion project - some questions

Have you thought about filling the whole battery with a non conductive cooling fluid so it can be cooled easily a...

Re: Antiscab's NWH10 Prius plugin Lithium conversion

The gen 2 would probably do better, does yours have the ev button? It sure does. By using two current shunts, (a 75mv 200A and a 75mv 100A) only 1/3rd of the current should go through the original battery ecu current sensor, meaning the original battery guage should be rescaled to 19.5Ah I really l...

These border issues are getting worse eh :lol: No worries, maybe a few more tired EV packs will come up in the future that I can scavenge a few cells from ... or maybe even the whole pack if the price is right :)

Re: 4Springs' Brumby

With NMCs, the balancing is done at any voltage, so the end of charge situation is different. It is spending hours in the last top-up phase. I've found that the cell voltages are the same (about 4.02 v) 24 hours after charging is finished. With the balancers operating all the time, how do you deter...

Re: what is peoples thoughts on Active Equalizer Balancer Boards?

It is a bit big. You would need 4 units to do a 14S lithium pack which would be almost the same volume as a cell. Not exactly sure how you would do a 14 cell in series pack, 16 in series required 5 units, one for each 4 cell group and one to balance the 4 x 4 cell groups. If you balance in 2 series...

How many do you have? I'm interested as I need a few as well.
Chris, what is the physical size of these cells and how many do you have?

Re: 4Springs' Brumby

Does your BMS sense high cell voltage to stop the charging as well as the total battery voltage? The BMS we built for house battery use has the high cell voltage stop as a secondary protection and drives a timer. The timer can be set anywhere between 1 minute and 1 hr, it then senses for another hig...

Re: Solar panels in series / parallel

As to the inputs of those MPPTs, generally there's no problem with putting two separate arrays of equal voltage in parallel, but any more than three strings in parallel will need fuses on each string. I think that's right @weber ? No. Any more than 2 strings in parallel requires a fuse in each stri...

Re: Solar panels in series / parallel

If you have multiple strings of series connected panels in parallel, you will need blocking diodes at the point the series strings join together in parallel to stop the panel series strings in full sun back feeding into the shaded strings. I know some here argue that blocking diodes are not required...
