US Electricar has only been sold with lead-acid. Remember - this was in 1994! Probably the writer is confused with the Ford Ranger factory EV which was initially released with lead-acid and later, I believe in 1999, became available with NiMH. This was the same path as the EV1 followed. Drawback for some NiMH factory conversions was that the engineers chose to recharge with the car's AirCo running to avoid high temperatures on the pack, but this made charge efficiency very low due to the amount consumed by the airco and not used to actually charge the pack...

This is the first I've heard of USE using NiMH. All the USE cars and trucks I've ever heard of used Hawker Genesis lead batteries. Do you know what brand / type of NiMH were fitted, to which models, and when? > The only other solution I came up with is a lot more work and may not > have the kWh capacity for NiMH pack that you seek by using many small > format NiMH > cells: If you're thinking of a massively parallel array like the one Tesla uses for lithium cells, I think you'd have some logistics problems. NiMH cells don't play nice when charged in parallel. You'd have to break all the parallel connections and charge each string with its own charger. If you needed a 30kWh battery at 300 volts, using my favorite NiMH cell, the Panasonic (formerly Sanyo) Eneloop at (IIRC) 1.2v and 1.5ah, you'd need a 250s 67p array. That means 67 300 volt chargers and 67 contactors. Whew! There's also the matter of cost. Last I checked Eneloops were around $2.50 each. You'd need (250 * 67) == 16750 (!), total cost $41,875! For that much, you can buy an entire brand new Nissan Leaf or Kia Soul EV, and have more than pocket change left over. I think your first idea was the best one. I'm sure Battery MD isn't cheap, but I'd hope that Kitty Rodden would charge less than that.
