Electric vehicles use electricity as a primary or secondary power source instead of conventional motor fuels like gasoline or diesel. Using electricity stored in a battery to power an electric motor has natural advantages over the internal combustion engine, including quieter operation, zero tailpipe emissions, instant acceleration, and significantly cheaper operating and maintenance costs. Electricity can be used differently in vehicle applications – those applications are classified below:
Hybrid Electric Vehicles (HEVs)
HEVs are powered primarily by an internal combustion engine, but they also store electricity in a battery that assists in propelling the vehicle to improve fuel efficiency. Unlike a plug-in electric vehicle, the electricity used in HEVs doesn’t come from the electrical grid by plugging into a socket or charging station; instead, electricity is created through a regenerative braking process and through the internal combustion engine. HEVs cannot operate solely on electricity at higher speeds and rely heavily on the internal combustion engine at all times.
Plug-in Hybrid Electric Vehicles (PHEVs)
PHEVs use electric motors in conjunction with an internal combustion engine to power the vehicle, but PHEVs are different from HEVs because they plug-in to an electricity source and can store enough electricity on board to operate independently from the internal combustion engine. Depending on the model, PHEVs can travel 10-50 miles on electricity without using conventional fuels, but when the electric range is depleted the vehicle switches to the internal combustion engine and operates like an HEV for an extended range. PHEVs work great for commuters who can use their electric range to get to and from work during the week but occasionally need additional range for longer trips.
Battery Electric Vehicles (BEVs)
BEVs have no internal combustion engine and operate completely on electricity. They get their electricity by plugging into a power source, whether that is an electric vehicle charging station or an electrical outlet at home. Depending on the power source they utilize, BEVs can charge in as little as 30 minute or as longer than 8 hours. The maximum range of a BEV depends greatly on the specific model, considering the Nissan Leaf as a range of around 80 miles and a Tesla Model S can travel 265 miles on a single charge.
We worked with the Colorado Energy Office to develop a great website, Refuel Colorado, that covers the details of each alternative fuel, including:
Workplace Charging: Get Your Work Plugged-In
HP’s Browyn Pierce, Global Real Estate Sustainability Program Manager, gives a run down on the benefits and considerations of workplace charging at a global company.
Deciding to install electric vehicle (EV) workplace charging has a number of positive outcomes:
- It helps employers attract high-quality applicants and retain important employees, acting as a competitive employee benefit
- It improves public image, leading to more publicity and potentially increasing client and customer-bases
- It reduces the perception of range anxiety, a major barrier to EV adoption
- Community members will be gracious for the improved air quality and health benefits as employees ditch their gas-guzzlers and switch to zero tailpipe emission EVs
- Businesses who switch their fleet to EVs will reduce their bottom-line as fuel expenses become a thing of the past
