Electric cars have to be slow with limited speeds, don’t they? If that’s your theory then you may have to re-evaluate after Ponway, California-based Plug-In Conversions Corp (PICC) completed a software upgrade conversion kit that enables all-electric mode driving at up to 70mph in a converted Prius.
Previous Prius Plug-in Hybrid Electric Vehicle kits have been limited by Toyota programming to a top speed of 34mph in all-electric mode with some kits allowing speeds as fast as 52mph using “forced stealth” mode. Yet this form of driving can force the electric motor to run above its recommended speed range and requires drivers to stop and restart the vehicle before its petrol engine can engage which can cause safety issues and erase emissions data.
Now however, PICC has created a software upgrade based on patented technology developed by Ewert Energy Systems. This allows the gas engine to turn on instantly when needed and initiates a controlled engine warm-up at any time to meet strict emission standards.
The software upgrade will also allow converted cars to operate in an enhanced hybrid mode at a variety of speeds. It boosts mileage while reducing emissions and maximises the use of the car’s electric motor in all driving modes. PICC also believes that its system can recoup more regenerative power from braking than a factory-installed Prius.
The conversion kit adds around 220lbs to the vehicle but rear springs are upgraded to maintain the rear height. The software upgrade will retail for $2,000-$2,500 and be made available for sale later this month.
