Specifications current and future:
1. Accomplished NO holes drilled or modification to Factory Five structural members
2. All components have plug and play attributes. We are still tweaking, but, are confident four
individuals with reasonable mechanical skills could install in a weekend.
3. Performance characteristics:
a. max 40kWh pack which can be sized to handle less miles and less cost. This is the maximum
size we can fit in the Ford Coupe.
b. voltage for the 40 kWh pack will range from 156 minimum to 201 maximum.
c. 1000 amp controller
1. option to go to 500 amp controller
d. 11" Kostov DC motor with five speed manual transmission and NO clutch required to shift gears
1. option for 9" or 11" NetGain motor and manual transmission and NO clutch required to shift gears
2. option for dual 9" or 11" NetGain motor and no transmission required
a. can switch the dual motors from series to parallel as an option as well
e. option for AC or 3-phase DC motor and controller which is good to 108 volts (good for mountain driving and regenerative braking).
4. AutoMeter gages:
a. Speedometer / Odometer is factory stock from AutoMeter - Green Cycle Design Group has built a board to interact with electronics so no need for cable from transmission to dash
b. Tachometer is factory stock from AutoMeter - Green Cycle Design Group has built a board to interact with electronics.
c. Volt meter is a factory stock tachometer from AutoMeter with a modified face plate by Green Cycle Design Group and specially designed circuit board to interact with electronics. There is a lack of industry standard gages which can handle the volts and still be able to read the dial. Green Cycle is implementing an industry standard 3.125" dia meter with percentage marks of charge instead of showing actual voltage. With smaller gages the user would not be able to figure out if they are operating at 180 volts or 175 volts. By using percentage we can adapt this meter to any vehicle and the user can see if they are in the plus or minus side of the pack voltage to help visually see if they are hurting the pack or not. This will help prolong the battery life.
d. Amp meter is a factory stock tachometer from AutoMeter with a modified face plate by Green Cycle Design Group and specially designed circuit board to interact with electronics. Due to a lack of industry standard gages for 1500 amp meters, Green Cycle has designed this meter with an algorithm based look. When you are running at 1000 amp you had better not be concentrating on the gages. When doing everyday driving, you need to concentrate on amp draw. Our amp meter does just this, it has a wide display between zero and 300 amps so the driver can see and compensate to conserve energy easily. After the 300 amp mark, we start to bring the numbers closer together. As you are drawing more amps correlates with accelerating quickly and the need to concentrate on the road.
5. Safety has to be number one:
a. Kill switch mounted where either the driver or passenger can break the electrical connection from pack to controller.
b. Battery Management System (BMS) to each 3.4V cell to prevent over charging or deep discharge. This extends the life of the batteries.
c. Electronics are in place to prevent the owner from driving off while the vehicle is charging.
d. Specially designed battery encloser made from fiberglass to reduce the possibility of electrical shock.
e. Specially designed battery hold down plates with Plexiglas viewing of the BMS for each cell.
a. Implementation of the new industry standard J1772 plug will be incorporated within the next 30 to 60 days.
b. 110/220v charging system:
110v is more for opportunity charging or for lower voltage vehicles. The 40 kWh pack would take about 15 hours to charge at a rate of 6 amps.
220v is more for higher voltage systems and would take about six hours to charge this 40 kWh pack at a rate of 23 amps.
7. The fun stuff:
a. Range is very dependent upon how the individual drives, the speed and terrain. We are estimating this pack to handle 150 miles at 55 mph on fairly flat ground. We still need to break in the pack and balance all of the cells before an accurate number is given out. We have the NCCAR facility, in Roanoke Rapids, who are willing to allow us access to their test track once we have new tires and the front end aligned.
b. 0 to 60 has not yet been tested as we need a good straight stretch of road for this test. Initially we had hoped for eight seconds. After the first test drive we were well under this. My guess is around five seconds right now (starting in 3rd gear), but, still need to be tested in different gears as well.
