The Chevrolet Volt (now discontinued) had comparatively large top and bottom protection buffers (regions A and D above) that dynamically changed as the battery aged. While the larger buffers meant less energy for driving, it resulted in a longer-lasting battery pack. Given the larger SOC buffers...
“By using the battery pack’s container and the battery cells themselves for rigidity, the overall weight of the vehicle can be reduced. Advantages includegreater range per kWh of battery packinstalled, better handling, and great potential for simplified vehicle assembly (which should reduce cost)...
Traction battery pack: Electric vehicle battery (EVB) is another name for traction battery pack. It provides electricity to an electric vehicle’s motors. The battery serves as a power storage system. It stores energy in the form of direct current (DC current). Transmission: It transfers mechan...
Electricity stored in the traction battery pack is delivered to the electric motor. The motor converts this electrical energy into rotational mechanical energy. This mechanical power gets transferred to the wheels via the transmission/gearbox, propelling the EV forward. The accelerator pedal signals the...

The technology was in its infancy at the time, and so was battery technology in general. The battery pack was located under the rear bench and the electric motor was in the front. For the swap, the bench was folded away, the battery pack taken out manually, and a new p...
There are two reasons: charging performance and battery longevity. Most of the time you should only charge an EV to 80% because charging rates slow down dramatically past the 80% mark. And two, the long-term health of your vehicle’s battery pack is improved when kept below 100%. What ...
EV Circuits: TheBatt-BridgeBattery Out-Of-Balance Alarm An EV's pack consists of many cells or batteries. In theory, they are all identical. In practice, they aren't. There will always be a "weak link" somewhere in the pack. That's the cell that limits your range, and limits how ...
Kurt Kelty, Vice President, Battery Cell and Pack atGeneral Motors, talked about the current state of EV sales and progress, and how GM is investing in new technologies to drive increased adoption. At the outset, he acknowledged concerns about EV sales. “Let’s review what happened this yea...
