Greener Energy can provide you with a hard or soft top battery powered car. We can also advise on hybrid electric cars and fuel cell systems.

There are 27 Lithium ion cells mounted under the bonnet in 9 groups of 3. A further 75 cells (25 groups of 3) are mounted at the back of the car. The total of 34 groups of cells gives 300Ah at a nominal 125.8 Volts (3.7 V per cell). The available power from the batteries is fed to a series wound dc motor via a 500 Amp controller. The controller and power relays are just in front of the batteries. The motor is beneath the batteries and drives the front wheels via a reduction gear and differential. </p> <p> Also situated under the bonnet is a dc voltage converter to supply the normal car electrical systems and to charge an emergency hazard warning and lighting battery </p>   Behind the seats there's enough room for your shopping, or a folding toothbrush. In the picture above the battery cover has been removed to give access to the rear batteries. There are two banks one above the other.   Our Electric Jester is an ideal commuting vehicle, great fun in the summer and for the colder days, up with the hood and on with the heating. A gas fired air blown heater is mounted under the dash fuelled by a small butane or propane cylinder.   The Jester has been tested according to European standards to derive the urban cycle and extra-urban cycle energy consumption and range. The car is shown here during tests on the rolling road. During these tests a maximum speed of 114 km/h (71 mph) was recorded. The energy consumption was 121 Wh/km for the urban cycle and 155 Wh/km for the extra–urban cycle. This equates to a maximum range of 326 km (202 miles) from a full charge of the batteries. Only 33 out of the 34 groups of batteries were in use at that time.

 

The power is provided by 102 Lithium ion cells each of 100 Ah capacity. They drive a series wound dc motor through an electronic controller with a maximum current limit of 500 Amps. The front wheels are driven through a single reduction gear and differential, overall ratio of 5.45:1. Forward, reverse and regenerative braking are derived electronically from the controller.
