2014 Chevrolet Spark EV in San Francisco
The 2014 Spark will also have a SAE combo charger for DC Fast Charging
General Motors (GM) has released some new information about its 2014 Chevrolet
, which it claims will excel in power and range.
According to GM, the 2014 Spark EV will have an oil-cooled magnet motor that is capable of 130 HP, or 100 kW. Coupled with the 400 lb.-ft. of torque, the Spark can reach 0-60 mph in under eight seconds.
“When our team set out to develop the propulsion system for Spark EV, we knew we had to provide surprising fun-to-drive acceleration with maximum efficiency,” said Spark EV Chief Engineer Chuck Russell.
“What we think customers will enjoy most is how fun
is to drive; it’s seamless and power is available at every stage of the drive. This will help us to provide an exciting option for those customers who are looking for an EV that’s as much fun to drive as it is environmentally responsible.”
Aside from power, Spark has another attractive feature: it's charging abilities. According to GM, the 2014 Spark will have a SAE combo charger for DC Fast Charging, allowing an 80 percent charge in just 20 minutes. This will certainly allow for more EV range within Spark's lithium ion battery pack, which will be over 20 kWh.
Last year, it was announced that the Spark would use a different battery pack from the Volt after an investigation was launched into the cause of a fire during NHTSA testing. Instead, it was said the Spark would use batteries built by A123 Systems. The A123 batteries are less fire prone as they use
lithium phosphate chemistry
. However, A123 Systems just
recently filed for bankruptcy
GM also made sure to mention that the Spark EV's motor and drive system will both be manufactured in early 2013 in the United States -- which is a first.

Yes. At fairly moderate temperatures the system doesn't hurt at all. However it can help a bit by keeping the battery pack at its optimal temperature, this also helps with durability and long term performance.
At more extreme temperatures, even though you're using more power to heat/cool the pack, it actually still results in a net increase in range over simply letting the battery pack strain along at temperatures outside its happy operating range. It also significantly improves long-term reliability/performance. Look at the Leaf in very hot weather to see an example of why air-cooling is not always sufficient.
I suspect the range given is typical use in somewhat moderate temperatures. You'll lose some range depending on a number of factors including temperature, however the liquid cooling system will be more effective at mitigating these problems in very hot weather than air cooling.
