Subaru has released a second generation battery-electric vehicle, the G4e (for “Good 4 earth”). The 5-seater has a maintenance-free 65-kilowatt electric motor, and features high energy-density vanadium enhanced lithium-ion batteries, which give the G4e a 124 mile (200km) range from a charge (more than double the first generation R1e’s range, previous post) and using a quick-charger it can be charged to 80% in only 15 minutes.
The increased range can be attributed to advances in lithium-ion battery technology. Using a new high-capacity vanadium battery material, the capacity of the positive terminal is increased two to three times, resulting in an energy density about twice that of the previous model.
The aerodynamically-efficient, triangular shaped body has a coefficient of drag of 0.28, which, along with a lightweight body helps to get the most from the battery pack, which is located under the floor of the vehicle to keep a low, stable center of gravity.
Recharging the batteries is facilitated through a plug located in the front bumper. A normal full charge takes about 8 hours, which will deliver about 200km of normal driving and could be made overnight at your home or at your place of work. A quick-charger allows the battery to be charged up to 80% in about 15 minutes at parking lots outside supermarkets, other parking facilities or at charging spots (previous post) along the highway. Either way, energy per mile is a lot cheaper than gasoline – as low as a tenth of the price if using off-peak overnight rates.
