Tesla Roadster - Specifications - Recharging

Recharging

The Tesla Roadster uses a proprietary charging connector, although Tesla sells a mobile adapter that enables recharging with an SAE J1772-2009 connector. The vehicle can be recharged using:

• A wall-mounted 208–240 V, 70 A maximum current Home Connector. This appears to be an OEM version of the TS-70 charging station from ClipperCreek.
• A portable 120–240 V, 40 A maximum current Universal Mobile Connector cable that can plug into a NEMA 14-50 receptacle and other 240V receptacles using adapters.
• A portable 120 V, 15 A maximum current Spare Mobile Connector cable that plugs into a standard North American domestic socket.

Charging times vary depending on the ESS's state-of-charge, the available voltage, and the available circuit breaker amp rating (current). In a best case scenario using a 240 V charger on a 90 A circuit breaker, Tesla documents a recharging rate of 56 miles (90 km)-of-range for each hour charging; a complete recharge from empty would require just under 4 hours. The slowest charging rate using a 120V outlet on a 15 A circuit breaker would add 5 miles (8.0 km)-of-range for each hour charging; a complete recharge from empty would require 48 hours.
