Battery power can be expressed as kilowatts. Think of the nominal voltage times the cranking/running current; P - EI.
Battery energy is power times time. Usually they are rated in ampere-hours, but times nominal voltagetimes time equals energy. Since the battery discharges, the voltage falls with time, so it's difficult to make accurate comparisons without instrumentation. The 35 kW doesn't make sense to me. If it's a fuel cell, it has a constant output as long as the hydrogen is flowing. They are rated in watts or kilowatts of continuous power. Is there a fuel cell and a battery? Don't have time to look at the website right now.

The reference is: The Equinox Fuel Cell uses 35 kW of NiMH batteries in a mild-hybrid configuration. In its next generation fuel cell vehicle, GM could achieve a range exceeding 300 miles by reducing vehicle weight, having a more battery-dominate full-hybrid design such as E-Flex, using its fifth generation fuel cell, and by switching to lithium batteries. I know there is a difference between kW and kWH. It is my understanding that when used with batteries it means that the battery holds 35000 watts of energy. This would push an electric vehicle 140 miles. If I am mistaking would someone explain the difference. http://www.cleantechblog.com/2007/11/gm-takes-lead-with-110-hydrogen.html Thanks ...
