PHEV Technology and EV Technology
Plug-in Hybrid Electric Vehicles (PHEVs)
Plug-in hybrid electric vehicles (PHEVs), also called series plug-in hybrid electric vehicles (SPHEVs) or range extended electric vehicles (REEVs), utilize rechargeable batteries that can be restored to full charge by connecting a plug to an external electric power source. PHEVs store energy in batteries and have an internal combustion engine to extend range.
PHEVs provide the benefits of an electric car while maintaining the same driving range as conventional vehicles. PHEVs travel in an all-electric mode for the vast majority of common local driving and only use traditional fuel when it is driven beyond the battery range. When the battery’s electric charge is depleted, a downsized gas engine is used to recharge the batteries as the vehicle moves. PHEVs use an internal combustion engine exclusively for recharging the batteries—rather than directly powering the wheels. This charge-sustained mode allows the driver to obtain considerably better fuel economy compared to the base gasoline models.
PHEVs can be charged up at night when system wide demand for electricity is low. They tap existing generating capacity that is not fully used rather than increasing demand for new capacity. EVs and PHEVs can be plugged into any standard household 120V outlet. To get a significantly faster charge and optional internet connectivity, a Level 2 charging station can be purchased.
ALTe’s Plug-in Hybrid Electric Powertrain System
Designed with Fleets in Mind
• ALTe’s plug-in electric hybrid powertrain system enables existing light duty trucks and vans to
drive up to the first 38 miles (depending on vehicle type and driving condition) in all-electric mode.
• When driving beyond the battery range, ALTe’s system obtains significantly better fuel economy
in charge-sustained mode compared to the gasoline model.
• For a typical 50 mile day, the vehicles will obtain up to 108 mpg when combining the 38 miles
driven in all-electric and 12 miles driven in charge sustained mode.
• When longer trips are required, there’s no anxiety with total range capacity of about 300 miles.
Electric Vehicles (EVs)
All-electric vehicles (EVs), also called battery electric vehicles (BEVs), are propelled by an electric motor powered by rechargeable battery packs. EVs are very reliable and require relatively little maintenance. EVs have 10 times fewer moving parts than a gasoline powered car. There's no engine, spark plugs, valves, fuel tank, tailpipe, distributor, starter, muffler or catalytic converter.
EVs are efficient. Electric motors convert 75% of the chemical energy from the batteries to power the wheels—internal combustion engines (ICEs) only convert 20% of the energy stored in gasoline.
The energy stored in the EV’s rechargeable battery supplies power to a motor controller. The motor controller is a device that controls the amount of power supplied to the electric drive motor(s) based on the position of the accelerator pedal. The motor turns a transmission, and the transmission turns the wheels.
Refueling an electric vehicle consists of connecting the vehicle to an outlet or charging device that is specifically designed for charging an EV. Recharging time varies, depending on the battery type, capacity and the voltage/current output of the charger. Most BEVs can be fully recharged in about 6 hours. Because the batteries are recharged from the utility grid and from regenerative braking, EVs produce no tailpipe emissions.
