Groupe Renault, Connected Energy install EV charging with 2nd-life batteries at highway rest areas

Green Car Congress

The E-STOR technology developed by Connected Energy uses second-life batteries from Renault electric vehicles. With the E-STOR system, the batteries are recharged at low power, and the stored energy is then released at high power. Electric vehicle batteries generally have a service life of eight to ten years.
