Because the average, daily, one-way commute is less than 20 miles, Level 1 charging with the L1 PowerPost™ EVSE makes the most sense for longer-term parking. The low current-draw of the L1 PowerPost EVSE minimizes any impact on the peak energy demand at your facility, thereby reducing the risk of higher energy rates resulting from EV charging. The L1 PowerPost EV charging station supplies drivers of plug-in vehicles with the energy they need to recoup the range from their daily commute.

For every hour that an electric vehicle is plugged into the L1 PowerPost EVSE, approximately 5 miles of range will be put back into the battery. 4 hours of Level 1 charging will give back to an EV driver the range they use for a typical 20 mile commute.

When charging on a Level 1 EVSE, most plug-in vehicles charge at a rate of 1.44 kW and draw about 12 amps. Based on an electricity rate of $0.17/kWh, the cost to re-fuel a 20 mile commute is under $1.

Here is the math:

$0.17/kWh energy cost x 1.44 kW charging rate = $0.245 cost per hour of charging

4 hours of charging x $0.245 cost per hour = $0.98 cost for 4 hours of charging

The L2 PowerPost™ EVSE is a low current draw Level 2 charger that saves facilities money that are interested in providing Level 2 charging. The L2 PowerPost EVSE provides a quick recuperation of range while keeping costs at a fraction of the price of other Level 2 EV charging stations.

Every hour that an electric vehicle is plugged into the L2 PowerPost EVSE will give a vehicle back 12 miles of range to its battery. With 2 hours of Level 2 charging an electric vehicle will recover 24 miles of range and in a four hour period can recover approximately 48 miles of range.

When charging on a low current Level 2 EVSE, electric vehicles usually charge at a rate of 3.0 kW and draw about 14 amps. Based on an electricity rate of $0.17/kWh, the cost to re-fuel a 24 mile commute is approximately $1 and $2 to recover the range of a 40 mile commute.

Here is the math:

$0.17/kWh energy cost x 3.0kW charging rate = $0.51 cost per hour of charging

4 hours of charging x $0.51 cost per hour = $2.04 cost for 4 hours of charging.
