Charge the race car from the Off-Grid DC Quick Charger in 90 minutes or just provide an energy boost in a few minutes to extend range or compensate for testing laps.

Charge the on-board energy storage from the grid in seven hours, overnight for example.

The Quick Charger provides independent energy on race tracks, during testing or at exhibitions and fairs.

Off-grid and off-board DC charging is efficient, fast and high power. No specific and costly installation is needed and the mobile system serves you wherever needed.

Battery-to-battery charging concept:

:: Off-board charger consists of power electronics and controls to perform DC charging of the car and of an energy storage system;

:: The system is mounted in a van and is therefore completely mobile;

:: Recharging of the energy storage system can be done wherever a standard power supply is available;

:: The system will allow for full charging of the energy storage from the grid in about seven hours;

:: The van brings the off-Grid DC Quick Charger to the electric car that shall be charged. This can be in any remote location without access to the right infrastructure;

:: DC car charging is designed for 25kW DC charging power to be transmitted;

:: A race car with 40 kWh battery capacity will be fully charged in about 90 minutes;

:: Any standard EV can get range recovery within a few minutes of charging;

:: Devices and protocols follow CHAdeMO standards;

:: The same safety standard apply as for the vehicle traction battery system and electrical design.

The Off-Grid DC Quick Charger made its first public appearance at the occasion of the Nürburgring Nordschleife lap record attempt in 2012.

It will be again presented at the Pikes Peak International Hill Climb 2013 by TMG and its EVlinkTM Charging Technology Partner, Schneider Electric.
