Peter, For bench testing the system, I thought about using 3 x AA rechargeable cells (in series, obviously) to simulate one lithium cell and then rig 2 or more of these to the same number of slaves. Can you see any issues with this? Will I have to remove the PICs from the unused slaves to avoid erro...

Peter, Re the dash buttons/LEDs - I've had a look thru the threads and can't find any info on what they all do exactly. I found the schematic for them ... BMSKeyMatrixLeds.jpg (?) So...

Thanks Peter... and USB so I can connect it to my ap easily! M

Peter, I had a night duty at one of the station offices at work the other night and managed to get the about 60% of the master and 2-and-a-bit x 16-slave boards populated. A couple of things came up... Any chance you could put a really high res image of http://www.solarvan.co.uk/Life/LifebattahCells...

ChrisB, Had the web site you posted put a bit more info on it I would have posted the same link. Unfortunately, it is a very lacking and still under development esp the full protocol including connector design (subject of another Japanese standard so probably available elsewhere) but mainly all the ...

Hi All,

Some wag in 'senior management' has decided it would be a good idea to send me on a course in Orpington, Kent (BR6 0TW) for 2 weeks and I can't find anywhere to charge the old EV. Anyone got any ideas?

Regards, MW.

Maybe they are signing up to the CHAdeMO Fast Charge Protocol (and hardware?) that Mitsubishi (iMiev) uses - full charge in 30 mins - 50kW output from 3 phase 240V supply. ESB ecars in Ireland are using these for their recently announced nationwide fast charge infrastructure.

For anyone that is interested here are the details of my VB6-based BMMS monitoring program I use on my EV - a Daihatsu HiJet micro-van which has a Netgain Impulse 9" motor, Belktronix controller and 38 x Thundersky LFP160 LiFePO4 cells giving a nominal pack voltage of 120V - see http://www.eval...
