Enginer PHEV Latest Improvements


  • New and advanced lithium-ion battery materials and structure ensuring safety, stability and high capacity
  • Two assembled battery packs replacing previous 32 individual cells, with quick connections to other components
  • Built-in temperature sensors. Should overheat does occur, BMS will disconnect the charger or shutdown the converter to prevent thermal event


  • System total voltage reduced from 58.3 V to 55.5 V to avoid over charge;
  • Improved charging profile with fastàtrickle charging currents to prevent system from over-charge;
  • Trickle current charging maintains stable cell voltages while charging batteries fully;
  • Timer based charging avoids non-stop charging to enhance safety.

DC-DC Converter:

  • Upgraded from previous 3KW to the current 5KW output, enabling almost non-stop All-EV drive till all batteries are depleted;
  • Inside and outside ventilation improvement reduces system operating temperature;
  • High standard production techniques and top quality electronic components used;
  • Neat and trendy design and structure.

Battery Management System:

  • Highly efficient and fully functional inductive active BMS monitors, balances and manages batteries, with 2A charging current to any individual lower cell.
  • Disconnecting the charger to avoid over-charge once an individual cell exceeds 3.8V.
  • Disconnecting the converter to avoid over-discharge if an individual cell drops below 2.0V.


  • Streamlined wiring for charger, batteries, BMS, converter, circuit breaker connections;
  • Nickel electrophoretic coated copper terminal connectors and screws on batteries to reduce internal resistance;

System Structure:

  • Reduced enclosure box height to allow trunk floor cover being fastened easily;
  • Re-designed enclosure box handles without large nuts inside leaving inner sides flat for easy battery installation / maintenance;
  • Integration of enclosure box with mounting brackets and the use of pivot nuts simplify system installation, saving at least one hour installation time;
  • Strong fire extinguisher holder;
  • Rubber plates under enclosure box to absorb shocks (Prius original heat insulating felt on right hand side of trunk bottom should be kept);
  • Easy install, more durable and professional look driver’s switch panel;

* Structure improvements largely reduce installation time from previous 4-8 hours to 2-4 hours.

* Plug-in Hybrid Electric Vehicle Conversion (PHEV)

The 4-KWh kit provides up to 20EV / 40 blended miles range per charge which will save about 260 gallons of gasoline per year.  You could double your savings to 520 gallons if you charge at least twice a day.

PHEV upgrading system is not limited to Prius PHEV conversions. The technology can be applied to any hybrid vehicle or even electric car. If PHEV system is adapted in a new vehicle, the vehicle will be qualified for $2500 federal tax credit according to the Recovery Act.

Note: Actual results may vary.  PHEV efficiency depends upon your driving style, speed, distance, terrain, and charge frequency.
