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

Re: [EVDL] 12v tales

Also, one particular thing that I like a lot about Meanwell is that they actually specify their power supplies to work from DC. Usually 130 - 370 VDC. And it is a Taiwanese company, so they tend to supply higher quality than China. The SP-750 has a built-in PFC front end, not important for DC

Re: [EVDL] 12v tales

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

Finally, Back to Lead acid and a FOUR WIRE EV! (Something I can maintain)! (4 wires, means 2 from the battery, and 2 to the motor and a controller in the middle. Done)... I have given up on modern EV's (two THINKs) who are BRICKS because the computer in them thinks something is wrong and they
