Re: [EVDL] 12v tales

Do NOT use a Li-ion 12vdc battery in your Tesla. It probably is a 12vdc, not a 13.5vdc like the lead/acid is. You will destroy the Li-ion. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/12v-tales-tp4682367p4682446.html Sent from the Electric Vehicle

Completely agree - with a small reservation: You don't want to use a no-name converter in your expensive car. I made that mistake once, won't do it again. I will only use name-brand equipment. In my EV's case, I'm using the Meanwell 750W 15V (SP-750-15). I've turned the voltage down to

Re: [EVDL] 12v tales

One thing I haven’t seen mentioned here is that power converters specifically designed to convert traction pack voltage to 12 VDC are expensive, whereas generic power supplies that do the same thing for line voltage are cheap. Almost any “universal” switching power supply designed to work from

Re: [EVDL] 12v tales

I've had a few occasions where the DC/DC converter was the only 12V source for the EV. Under normal circumstances 500W seems fine. Extreme loads (winter with headlights, full fan, full wipers, lots of braking and vacuum pump) will trip the fuse/breaker. Slightly OT, does anyone have a good way

I made a pigtail "jumper cable" for my conversion. I have used it once. I put it across 4 LFP cells and just touched the digital relay input to enable the DC-DC converter. Once it came online, I didn't need the battery, and I could remove the jumper. Mike On June 5, 2016 7:20:32 PM MDT,
