Current Prius Plug-In Hybrid with lithium-ion batteries
Typically, we observe production capacity of lithium-ion batteries, as those are used in most of today's electric cars, but to have good reference it's beneficial to check what is happening with NiMH too.
Recently, Toyota Motor Corp.'s subsidiary Primearth EV Energy Co. announced that will increase production capacity for nickel metal hydride batteries in Miyagi Prefecture in northeastern Japan.
In less than a year, capacity should grow by a few hundreds thousand packs for hybrid cars to 1.4 million annually.
At such a level of sales, even the tiny battery packs means that Toyota consumes more than 2 GWh a year.
According to the article, Primearth EV Energy sales for fiscal 2013 amounted 150 billion yen, which is almost $1.5 billion.
