NiMH is perfect for the Chevy Volt. NiMH likes to be left only partially charged, contrary to Lead. NiMH charges better in cold weather, and does not lose as much power while discharging in cold weather. This fits the discharge cycle of the Chevy Volt perfectly, as we demonstrate with our RAV4-EV.
Adjusted for inflation, current cost might be $1000 per kWh in small quantities, $500 in larger, and $350 in production quantities.
Here's what CARB said, which sounds doubly facile now:
"...NiMH batteries for the EV types now deployed in California EV would cost EV manufacturers between $9,500 and $13,000 in the approximate quantities (10k-20k packs per year) required to implement the year 2003 ZEV regulation, and approximately $7,000 to $9,000 at the 100,000 packs per year level. These projections exceed the automobile manufacturers' cost goals by about $7,000 to $9,000 in the nearer term and by approximately $5,000 at automotive mass production levels..."
Imagine, CARB pandering to the Auto Alliance! Now, $30K for an EV sounds awfully cheap, and CARB's "analysis" makes even less sense.
On the basis of this moderate cost estimate, they killed EVs, and relied on $1M fuel cell cars?? With no supply of Hydrogen gas???
