Electric Vehicle Charging

Electric Vehicles are fueled by electricity and can be recharged at a charger installed at your home or workplace, or at many other charging locations such as Costco and your local shopping mall.

Currently, there are two different charging methods, conductive and inductive. The conductive system is similar to the traditional plug in that it uses metal-to-metal contact to transfer the electricity. The inductive system uses a paddle shaped device to transfer the electricity via induction or a magnetic force. Beginning with the 2006 model year the conductive system utilizing a specified connector will be required for all new full function electric vehicles; thus, standardizing charging so that every car fits every plug.

The charging system performs two basic functions. The first is to convert or rectify the alternating current (AC) distributed by the utility provider to direct current (DC) needed to recharge the vehicle’s batteries. The second is to regulate the electricity in a manner consistent with the battery's ability to accept it. To obtain the desired amount of electrical power, individual fuel cells are combined to form a fuel cell stack. Increasing the number of cells in a stack increases the voltage while increasing the surface area of the cells increases the current.

All chargers have numerous safety features that reduce or prevent the risk of accidental shock.

Charging time varies depending on how “empty” the battery is, how much energy the battery holds (or how big the tank is) and other factors. In general, it takes approximately two to five hours to recharge vehicles that are ¼ to ¾ full and approximately six to eight hours to recharge vehicles that are on ”empty.” However, you'll probably be working, sleeping, shopping or watching a movie so it really doesn't impact your ability to use your car.
