A123: Increasing 48V battery power up to ~25 kW enables advanced mild hybrid capabilities with greater fuel savings

Green Car Congress

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. To address these needs, the A123 team presented a high-power, lithium-iron-phosphate chemistry with excellent rate capabilities.

What watts?

Electric Auto Association

No EV charging is 100% efficient, not plug-in charging, not wireless charging, not DC Fast Charging (DCFC), not AC home charging. Regardless of how or where you charge, not all the electrical energy pulled from the grid—those watts—will make it into the “fuel tank” (battery). Why does battery temperature matter? More info) 3.

More details about California’s proposal requiring bidirectional charging capabilities for all EVs

Charged EVs

You could do V2G through the DC port of the vehicle—this is what we are doing with school buses here in California, where our charging station converts AC to DC and then connects to the DC port of the vehicle to provide power. On the DC side, we are rolling out a charging station right now with Rhombus.
