I know many of you liked the Nut Rider 80s retro electronic instrument cluster. All those LEDs looked cool and would have gone nicely with my retro 80s ham gear. But there was simply no decent geography to put in a decent visible-easy battery gauge. Having run out of money and deciding not to get [...]

Reports have been coming in of a new type of air-charged battery which could provide up to ten times the energy storage of a conventional lithium cobalt battery. Called the STAIR (‘St Andrews Air,’ where it was developed at Scotland’s University of St Andrews), it provides improved capacity via a porous carbon exchange cell lattice [...]

I must apologize for all these delays! Being a small outfit, the Echo has taken up considerable time but it looks very good now and will be delivered to the client soon. The BMS has been upgraded and looks pretty neat with the cosmic blue charge active LEDs added. My health has been a bit of [...]

While Ford are thinking of releasing a fully-electric work van in 2010, Mercedes has got in on the EV action with a proposal for a new EV in a B-class range, namely the BlueZERO.

Here’s the latest video. It’s got stuff about water boilers, IGBTs (which I talk about further in this post), a brakes test and revs testing. I’m guessing there’s probably only a couple more videos to go as finish time approaches. Most of the scenes in all the videos have been shot on a Nokia N93 [...]

That being the press this time, but you have to hand it to them for making the effort to grasp the latest technologies without adding pre-conceived cynicism in a minefield of broken promises and dead-end projects that seem to litter the EV horizon. The better end of town, namely the professional technology arena as well as [...]

After successfully testing the drivability, it’s back to the workshop to get stuff removed to paint the battery racks and sort the best place for the charger. I did a mock-up Zivan so I could squeeze it into a place in the pillar where Nathan cut a piece out for access. The test proved that there [...]

This has been sitting around in the garage for some time now begging to be installed. When we rushed to prepare for the EV demo, the brakes weren’t finished – they were hard-pressed to slow down one could say. As most cars have vacuum pumps for power-assisted breaking, it’s a must-have for my car too, [...]

For accessories, a DC to DC converter (such as the Curtis 1410) is used to buck down the 144v (actually higher on peak charge) from the Thunderskys to an isolated 12-14 volt source for accessories such as lights, radios, airhoon, ahem I mean horn etc (which an alternator would otherwise handle in a gas car). DC-DC [...]

A few people are asking me why I have chosen Thundersky Lithiums over conventional lead-acid deep cycle batteries. Firstly, lithium phosphates are lighter than deep-cycles, and Lithium polymers are even lighter again, approximately half the weight of the phosphates, making them useful for a variety of applications other than just electric vehicles, such as electric [...]
