ROHS directive and electric vehicles?

Hi all.

Seems that the EU have again shot themselves in the foot by totally banning NiCad batteries, as it seems that the recycling of old batteries into the electric vehicle (EV) market is not allowed.

This effectively means that LiIon is the only acceptable choice, and given the lack of a certified pack design for automotive use means that they have effectively outlawed electric vehicles for the forseeable future.

So the next time you fill up at the pump and see the ridiculous price of petrol, you can blame the idiots in Brussels :(

Wait until we get the RoHP, Regulation on Harmful Politicians :)

Otoh, I have seen at least three solutions to that bind hydrogen to a metalpowder or bricks. Which will release it with a small heater.

I don't think anyone was using Nicad anyway. Li-ion seems to be the way since only it appears to be remotely capable of the energy density needed.

Fuel cells are the alternative.

maybe you havn't moticed the trends with supercaps?

150 Farads!?!?

Hydrides are monumentally heaver than the hydrogen itself though.

What is the leakage current?

I think its quite low, they are being used as backup cells for low power circuits.

hmm, I wish I could... ah here is my old elna catalog...

2.5V 100F hmm its not clear, looks like 30uA

"Panasonic's GoldCaps comprise several ranges of pc-board-mounting capacitors with values of 0.1 to 2F at 2.3 or 5.5V, targeting a variety of data-retention and -backup functions. The company recently added the Ultra-Power (UP-Cap) device, which it aims at emerging 42V automotive applications. It specifies these devices, which come in cylindrical-can format, at 500 to 2500F and 2.3V and claims a lifetime of 2000 hours at 2.3V and 60°C. Panasonic's automotive-device-marketing specialist Matthias Frey, describing the use of an array of 40 to 50 capacitors in a vehicle, anticipates that the technology will reach the full 75°C rating that the automotive industry would like to have by 2005 or 2006. Panasonic is currently building capacitor arrays to explore automotive applications as special custom projects. "

see, I'm not off my rocker!

2500F thats just crazy

If you actually take the bother to read the agreed text of the EU battery directive you will learn that it does *not* advocate "totally banning NiCad batteries".

It does, however, seek to reduce the impact all battery types have on the environment by a number of strategies.

In particular the use of NiCad batteries is well recognised in the directive for duties where their properties remain unequalled in performance at economical levels in the marketplace.

In a similar manner, neither are lead acid batteries banned.

I wonder about the law of unintended consequences with this ROHS stuff. How much extra pollution will be cuased by all the extra paper and work needed to support extra part numbers. How many people will be killed or injured by failed vehicle equipment with bad solder joints due to non-lead solder or due to the growth of whiskers. How much extra trash will be created by all the electronic gear that fails due to these problems. Its a classic case of letting beauracrats get in the way of common sense.

NiMH cells are just about as good as NiCad these days. The model car/plane boys have all switched over. NiMH cells can supply quite high current.

It's very hard to build a decent EV using NiCad, NiMH or Lead cells anyway.

Li cells are better and getting better. They just aren't available in quantity yet....

Probably all the cadmium in the drinking water.

Cadmium doesn't cause mad politician disease (more likely mercury!) and Cd is more likely to turn up in tobacco than drinking water!
