I was wondering if most EV's keep chargers connected to pack full time.
I want mine disconnected unless charging so that there is no pack voltage outside the battery box (charger is in the cab).
I have the DC fast charge contactors from a Tesla Model 3. They seem to be custom made by Gigavac.
They have isolated auxiliary contacts which I can use to enable the charger only when the pack is connected.
However, the coil resistance is only 1.2 ohms! At 12 volts each coil would draw 10A and dissipate 120W! What is the deal here?
Why such a low resistance? They must be using an "economizer" circuit right? Thanks, Al _______________________________________________ Address messages to ev@lists.evdl.org No other addresses in TO and CC fields HELP: http://www.evdl.org/help/
