[EVDL] Sequence of Events

2016-12-21 Thread ROBERT via EV
Does anyone know the sequence of events when an EV starts? Example: (1) Turn Key ON, (2) High Voltage to 12VDC converter energized, (3) Inverter logic power supplies energized, etc -- next part -- An HTML attachment was scrubbed... URL:

Which EV, there may be similarities but I don't imagine they are all identical except in the main functions. My EV has one main contractor so when it closes everything powers up at the same time. Some systems have a relay on the negative side that powers every thing but the inverter or control

Most EVs and Hybrids have at least three contactors. The sequence is: * Close One battery lead and check for leakage * Drop that relay and close the other lead with a series resistor and check for leaks * Bring the first one back in to power up still via the series resistor for a few millisecond

; Electric Vehicle Discussion List Subject: Re: [EVDL] Sequence of Events contactors There is no standard way of handling startup, so to say "most" is a bit misleading. What you describe certainly does not fit the sequence of either of my two OEM hybrids, nor does it match my two DIY EVs.

You have 3 of 45kwh packs in one EV? That's 135kwh ! I think you stole "insane" from tesla :) Peri -- Original Message -- From: "Roland via EV" To: "damon henry" ; "Electric Vehicle Discussion List" Cc: Sent: 24-Dec-16 7:39:06 AM Subj
