Electrification of transportation will be accelerated if public and private employers provide [[Infrastructure for EV Battery Charging|infrastructure for EV battery charging]] in their employee parking lots. Many governments, NGOs, electric utilities and other companies are now advocating and/or providing charging facilities for EVs.

Equipment for charging of EV batteries is classified based on the power requirements and the rate at which the batteries are charged.

'''AC Level 1 Charging''' uses low power (15 amps at 110 volts or 7.5 amps at 220 volts) for slow battery charging to provide 2 to 5 miles of electric vehicle range per hour of charging. Lower costs and higher efficiencies encourage widespread use of [[Level 1 Charging of EV Batteries]] despite its slower speed.

CalCars believes that most PHEVs need only a 1-1.5 kW charger, able to plug into ordinary 120V, 15A GFI circuits.  Since gasoline is available as a range extender, charging need be no faster than overnight.
 
−
* CalCars uses a '''Brusa''' NLG5 charger from MetricMind.com.  This is a $4000, 4kW charger capable of being reprogramed for any chemistry and any voltage output up to 520V.  It is invaluable for our experimentation, especially since, for our world's first PRIUS+, we didn't know what would be necessary.  A less flexible, lower power, less expensive charger may be more suitable for subsequent conversions.
 
−
* '''[http://www.delta-q.com Delta-q]''' is taking a strong interest in PHEVs.  They are the charger supplier for [[EDrive]] Systems' conversions and have begun working with CalCars on creating chargers for both our PbA and Electro Energy NiMH conversions.  These are high quality, programmable, and isolated chargers.

====Note about Sulfation====

RonG:  Important new PbA charging information from Tony Goulet at [http://www.odysseybatteries.com West Coast Batteries Inc.] re. Odyssey (and all PbA) batteries (after nearly 40 years of working with PbA batteries off and on, I am still learning more about them):
 
−
 
 
−
Sulfation of PbA plates does not only happen at low states-of-charge (SOC) as I used to believe.  Sulfur is deposited on the battery's negative plates corresponding to its depth of discharge (DOD).  After three days or so this sulfur becomes crystalized and can no longer be removed from the plate by charging.  This means that any portion of a PbA battery's capacity that is left in an uncharged state for three days is permanently lost, and the battery now has less capacity!  This can happen repeatedly, causing increasing loss of capacity.  (Of course, as I already knew, if a PbA battery is left in a very low SOC for long, the sulfur may grow crystal trees that often permanently short out a battery right through its separators.)
 
−
 
 
−
The second piece of this tale is that unless a PbA battery has been held at a constant-voltage absorbtion charging stage for 8-12 hours, SOC is less than 100%.  If e.g. 97% charge is achieved and the battery is not charged more completely for three days, the uncharged 3% of the capacity will probably be permanently lost to sulfation!  It is therefore very important to charge a PbA battery to 100% at least every other day -- and less than a quite long absorbtion charge period (including ~3% overcharge on new batteries, or 10-20% overcharge on older ones) will not suffice!

Electrification of transportation will be accelerated if public and private employers provide infrastructure for EV battery charging in their employee parking lots. Many governments, NGOs, electric utilities and other companies are now advocating and/or providing charging facilities for EVs. Building mostly Level 1 chargers would be the lowest cost strategy to serve the greatest numbers of EV drivers.
