Tinskey says one power utility might have proprietary standards for use within its own utility, but there are no industrywide standards today for communicating the power level of an EV to any utility on the grid, or for aggregating the data about where and when you can get the cheapest charge from any vendor and any power company.
The lack of standards is both a blessing and a curse for EV security because there is a potential to develop secure standards the right way, with participation from multiple vendors, says Tinskey. Fortunately, the EV industry has shown that it is willing cooperate on standards -- for example, the SAE J1772 charging standard is a five-pin plug used on the most popular electric cars, such as the Volt and the Leaf. This plug can transmit data securely from the car, including charge state and range.
Industrywide standards for handling EV data might be slow to develop, Tinskey says, depending on how many people buy the cars over the next few years.
To be sure, the technology to help EVs is mostly in place. Much of what's still needed involves developing the communication between charging station providers, the grid, and the new makes and models. Car companies are already analyzing the rich data from drivers; the next steps will be to use this data to develop better cars and an even more robust EV infrastructure.
