   If you read the caption for the photo, that’s the Governor of Michigan. And the article itself simply repeats the same info we’ve been hearing now for over a month. Old news.

   NiMH batteries found economical for Electric cars, cheap for plug-in hybrids

   “…Nickel-metal hydride (NiMH) batteries, employed in more than 1000 vehicles in California, have demonstrated promise to meet the power and endurance requirements for electric-vehicle (EV) propulsion…NiMH batteries have realistic potential to last the life of an EV, or at least ten years and 100,000 vehicle
   miles…”.

   Actually, we find it probably closer to 200,000 miles.

   “…plant commitments in 2000 could result in establishment of manufacturing capacities sufficient to produce the quantities of batteries required under the current ZEV regulation for 2003…”

   But GM sold control of NiMH to Texaco in 2001, which then was absorbed into Chevron.

   “…Current NiMH EV-battery modules have specific energies of 65 to
   70Wh/kg, comparable to the technologies of several years ago—reported in the BTAP 1995 report (1)—and major increases are unlikely. If NiMH battery weight is limited to an acceptable fraction of EV total weight, the range of a typical 4/5-passenger EV in realworld driving appears limited to approximately 75 to 100 miles on a single charge…”

   That’s 770 lbs., and 120 to 200 miles on a charge.

   “…Despite extensive cost reduction efforts by the leading NiMH EV-battery developers, NiMH battery cost remains a large obstacle to the commercialization of NiMH-powered EVs in the near term…”

   Even more of an obstacle after Chevron took control and sued Toyota and Panasonic.

   “…costs of at least $350/kWh, $300/kWh and $225-250/kWh can be estimated for production volumes of about 10k, 20k and 100k battery packs per year, respectively. To the module costs, at least $1,200 per battery pack…for the other major components of a complete EV-battery, which include the required electrical and thermal
   management systems…NiMH batteries for the EV types now deployed in California 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 production levels exceeding one hundred thousand packs per year…”

   That’s not an obstacle, that’s a price any EV driver would be happy to pay. And the cost for a VOLT would be less than half that, or not more than $5,000.

   la razon porla que escribo este mensaje en espanol, es porque no se escribir en ingles. pero estoy muy interesado en saber cual es el voltage de la bateria del auto. ‘volt” me parese un auto muy sofisticado lleno de muchos detalles pero hay un pequeno problema com el comsumo de energia. por favor haganme saber cual es el voltage requerido. ya que estoy trabajando en la creacion de un sistema que producira energia ecologica el cual podriamos incorporar a automoviles y reemplasar bateria, motor de gas,y el tanque de la gasolina si les interesa mi comentario y ropuesta pueden contactarme en el tel.713 540 1472 favor dejar mensaje o enviarme un email imbpropainters@aol.com att. israel b mendez
