The Californian company Enteligent is accepting pre-orders for DC-to-DC fast charger for electric vehicles which can be combined with solar energy to minimize emissions.

Designed as an alternative to Level 2 AC chargers, Enteligent TLCEV T1 EVSE eliminates energy loss due to DC-AC-DC conversion losses that would otherwise be a factor if installed at a location without a dedicated power source for the charger, the company said.

This system, which Enteligent says is the first of its kind in the world, allows DC fast-charging stations to be installed in locations where lower-power Level 2 charging stations were previously installed. And when the chargers are connected to solar arrays, Enteligent says they don’t need to be connected to the power grid. This reduces permitting and other complications and ensures that electric vehicles are charged exclusively with renewable energy, further reducing their carbon footprint.

According to Enteligent, the hardware supports fast Charging with up to 12.5 kWand is available with Tesla North American Charging Standard (NACS) or CCS-1 connectors. This setup is available for pre-order now with a refundable $250 deposit that will be applied toward an “early bird” price of $2,249.

Enteligent also announced that it has a 25kW bidirectional DC/DC charger to a “major logistics company” to charge electric delivery vehicles and had raised $6 million for further commercialization.

Solar-powered bidirectional charging could allow electric vehicles to serve as a backup power source. The Ford F-150 Lightning pickup truck for personal use already has such a feature, and General Motors has created an entire energy division to take advantage of bidirectional charging, which will soon be available on all electric vehicles.
