Believe it - it’s Pure Electric!
Since Friday, 9 December 2011 @ 20h05, Team-Freedom Won© has been driving our prototype electric car conversion to work, shops, restaurants, friends and family!
We are thrilled to report that after almost four years all systems are performing according to our high standards for reliability, safety and operability.
70 000kms/0 litres!
The vehicle selected for our first electric conversion was a Jeep Grand Cherokee with uprated suspension, which easily handles the 200kg net weight increase of the conversion - enter Freedom1©.
Our electric conversion is a five seater SUV with a motor capable of delivering 80kW continuously, with 600Nm of torque available, a practical 170km range between charges and is comfortable with a 120km/h highway driving.
The motor is a robust air cooled six pole three phase magnet motor, designed for heavy duty applications and ultimate efficiency. It is driven by a sophisticated microprocessor controlled variable speed inverter drive, capable of efficiently providing strong but smooth torque delivery through the motor speed range. The system includes regenerative braking for maximum efficiency and range.
The Freedom1 drive design consists of the motor connected directly to the transfer case via a short drive shaft, driving the front (optional) and rear wheels through the original axle differentials.
The 600V DC battery pack design is made up from a number of large format high performance lithium ion cells, produced by one of the world's leading lithium cell manufacturers. The vehicle is fitted with an on-board charger that connects at home or office to a simple custom installed high power charging supply, capable of charging a fully discharged battery pack within 6 hours. For everywhere else the vehicle can also be charged in 6-8 hours using an ordinary 16A 230V household socket.
EVs (electric vehicles) require almost zero maintenance andFreedom1©'s operating costs amount to a fraction of its ICE (internal combustion engine) counterparts.
