[EVDL] BMS cell pairs

[Lawrence Rhodes via EV]

It seems most battery pack builds use one bms per cell row.  That is two or 
three batteries in parallel using one BMS.  If I am using A123 batteries that 
could be up to 120amps for 2 in parallel. Must the BMS be rated for the full 
120 or would I go by the rated amps of the controller which in my case is 
40amps? How many batteries in parallel can I safely put on one BMS? Any 
recommendations for reliable BMS? Lawrence Rhodes

Elon Musk Doesn't Have A Problem With Modified Teslas
May 19, 2020  Just as long as you only tackle suspension, weight reduction
and body modifications ... companies like Unplugged Performance or T
Sportline offer modifications for those Tesla owners that are actual car
guys and driving enthusiasts, people who want their cars to look and handle
in a more sporty fashion than what the factory can offer ...

Re: [EVDL] pack-aging: Tesla has V2G

[Paul Compton via EV]

I'm on the Octopus Energy 'Agile' tariff, which means my electricity
price tracks the wholesale price every half hour. I have 3Kw of PV
installed facing roughly South and a further 1.2Kw split East-West. I
recently had a 5.6KWh grid tied battery installed. I just had my 7th
'plunge pricing' alert of the year, where for a few hours I would be
paid for any energy I draw from the grid. At the moment, I'm averaging
less than 2KWh import per day and I'm unlikely to be doing so during
the negative pricing times, but if I was doing significant miles in an
EV, I could install an EVSE with ITTT (If This Then That) integration
and be paid to top off the charge.

Re: [EVDL] Last straw with prius battery pack!

[Gail Lucas via EV]

Hi K O. Haven't seen you on the list for a long time. From your past 
posts I thought you were a woman, or am I confusing you with another 
list member?

I suggest that he consider an imiev.  It should meet his stated speed

BEVs.  Before he declares an imiev to be too small, he should measure.

 Hi Willie, KO and All,        Thanks Willie as I was confused too.        If I 
had that VW Fastback conversion I'd be putting in used Volt, etc lithium 
modules as could make it 150 mile range easily.   It's light, fairly aero so 
optimized, 24kwh should get him there.  16kwh for 100+ miles.      That's 
600lbs of Volt or 300lbs of Tesla modules  at 24kwh..      And switch the 
Prestolite with something more efficient. There are some great roll, brush on 
paints for boats to make it look great cheaply.        I've been looking for 
such a glider, VW bug, fast/sqback, older van especially , S-10  etc here in 
Tampa to do just that as have most of the parts, battery.  Any dead ones in 
Florida that need a home give me a call.      Jerry Hi Bento.On Thursday,
