All-electric range

All-electric range (AER) is the maximum driving range of an
Calculating AER is made more complicated in PHEVs because of variations in
This procedure uses the formula below to calculate an equivalent AER for vehicles that operate in blended mode:
Where GPMCD designates efficiency in charge-depleting mode, and GPMCS charge-sustaining mode as designated and dCD is distance in charge depleting mode.
A plug-in hybrid's all-electric range is designated by PHEV-(miles) or PHEV-(kilometers) km representing the distance the vehicle can travel on battery power alone. For example, a PHEV-20 can travel 20 miles without using its internal combustion engine, or about 32 kilometers, so it may also be designated as PHEV32km.
The all-electric range for BEVs has steadily increased in the last decade. In model year 2010 BEVs, the average AER is 127 km (78.9 mi), while in model year 2021 BEVs the average AER is 349 km (216.9 mi).[5] In model year 2021 BEVs, the median driving range was 60% of the median range of internal combustion engine (ICE) cars, a gap which will continue to narrow as more long-range BEVs are produced.[6]
The All-electric range has also increased for PHEVs over the past decade, increasing from an average PHEV range of 33 km (20.5 mi) in model year 2012 to 62 km (38.5 mi) in model year 2021.[5]
