Supercapacitors are not restricted to a narrow voltage window. Designers need only consider the voltage range of the system, which can be much wider than the narrow voltage range required by a battery. The supercapacitor can operate at any voltage below its ...
The battery bus bar configuration is somewhat convoluted to get a shunt between array 11 and 12 for the service plug on top of the pack. Battery assembly weighs ~24kg, the whole pack is about 70% the original weight. Battery hookup said all of these batteries were 80-90% or greater of the new spec 8Ah. I tested a random sampling and was in ...
