Terry's
prototype electric vehicle will feature two options for recharging the +90% efficient prismatic LiFePO4 main battery pack.
One option will be connecting to mains electricity via the onboard AC-DC power supply or an emissions free method by selecting the vehicle integrated solar array.
* The integrated electric vehicle solar array consists of 14x 6"x6"
mono crystalline solar cells
wired in a series and function as fairings or aerodynamic wind cutters which improve the vehicle's drag coefficient value.

The operator controls solar array output via a group of dpdt rocker switches. Directing the output to charge any two batteries/capacitors from either the main 24 volt battery pack, 12 volt battery booster pack or 10.8 volt capacitor bank. The two extra electrical energy storage packs, have been added for extended range functionality.
Harvesting kinetic energy by an extra sprocket mounted on the opposite side of the rear wheel to the electric motor, using five gears engineered to rotate a set of very small 3-phase alternators designed with multi-pole configuration to cut cogging torque. Each of these alternators convert alternating current to direct current with 74% efficiency. The electricity is stored in a bank of ultracapacitors, this power is quickly released via the propulsion booster switch. The regen device's structure is hand-built from polycarbonate.
