Case Study

The electric vehicle home charging experience can raise a lot of questions for new EV drivers — when is the best time of day to charge? How much will it cost? Years of pulling up to a gas station and seeing a price per gallon listed have conditioned drivers to expect predictable fuel purchases. But the cost of home charging is a black box. That's why Ford uses our Signal API to access the world’s most comprehensive utility price database and enable new features that help their drivers save money on home charging.

Read the case

As EV adoption accelerated, we needed a scalable solution that provides accurate data of utility rates across the US and Canada. The Signal API service enables us to help our customers charge their EV at the most cost-efficient times, reinforcing one of the value propositions of EV ownership.
