Using MightyBoyEV - Battery Upgrade Wiring Modifications - December 2010
I wish to acknowledge Rod Dilkes (EVPower) for suppling Li-Ion batteries, BMS components and chargers for this upgrade
And also for providing me with information needed to make it all work - nice to talk to someone actually using the technology and not just talking about it!
The final "Picturematic" of the Li-Ion wiring modifications for MightyboyEV December 2010
24 only Lithium Iron Phosphate (or LiFePo4) cells - 180Ah Sky Energy (or CALB - China Aviation Lithium Battery Co., Ltd)
24 only EVPower CM100 BMS Cell Modules
1 only EVPower BMS Master Unit for Elcon Chargers MCU-EV2-ELC x 2
2 only Elcon TCCH-72-16 24 cell 16 Amp Chargers (can be paralleled for faster charging if need)
* These two 100k "tie-down" resistors are used for monitoring any earth leakage such as carbon build-up in the brush area of the ADC motor that will occur over time
Note that the PakTrakr connections are not shown on the above circuit - please see the PakTrakr information if required...
A 12 volt Photoelectric Smoke Detector with inside/outside alarms....
Like wise an "Over-temperature" Warning Buzzer has been added....
Audio Alarm ONLY - NOT part of Interlock system
This start-up warning circuit now replaces the original sound generator I made featuring spoken voices….
The problem with voice start-up sounds was hearing the spoken audio messages above the audio from the cars sound system
For this reason I have chosen to use an industrial style sonalert (but at a low volume for a brief time) that can easily be heard above ambient noise
The perfect solution would be to link the start-up messages into the car audio system but life is to short....
Why a start-up sound? In my view I thought it was important to give the driver an audio indication that the EV was "Ready to drive"
Headlight warning circuit - including additional interior LED lighting - mainly for ignition key area etc....
