Here in the US, there are a couple of different ways to get your electric vehicle [EV] charged. The standard LI 120V charger typically takes up to eight hours to fully charge your vehicle. The LII 240V charger is a little faster, up to four hours charge time, depending on your model.
LIII 480V chargers are in the realm of fast chargers, or according to Tesla Motors, SuperChargers. The SAE J1772 fast charging standard, accepted by most manufacturers in the US, including Toyota, Mitsubishi, and Nissan, among others, has been eschewed by Tesla Motors in favor of its own SuperCharger standard.
Tesla Model S is an exclusive item, and the growing network of Tesla SuperChargers isn’t compatible with anything else, so don’t expect a long line at the nearest SuperCharger. In Japan, however, things are different, and this time, Tesla isn’t fighting the system.
Japan’s CHAdeMO fast charging standard is already well-established, almost 1,900 strong, and if Tesla is going to make a dent in the Japanese EV market, it is finding it easier to adapt than to rebuild.
To that end, Tesla Motors is developing a CHAdeMO-to-Model S adapter to enable new Tesla Model S owners, to begin later this year, to charge their Model S at any of Japan’s CAHdeMO fast charging stations in the country.
Here in the US, Tesla Motors is sticking to its SuperChargers, and isn’t planning on developing a J1772-DC-to-Model S adapter* any time soon. If Tesla Motors wants to make Model S fast charging more accessible here in the US, perhaps they will consider making adapters for the SAE J1772 DC Charging Stations.
*I wasn’t clear on the J1772 Adapter and the Tesla Model S. There are two J1772 Configurations, AC and DC. AC Charging on J1772 is limited to 19.2kW and DC Charging is limited to 40kW and 100kW. At the moment, there is no adapter for the Tesla Model S that is compatible with the DC configuration of the J1772 charger.
