Ford helps EV owners charge smarter

Arcadia works with Ford to improve the at-home charging experience for its electric vehicle (EV) drivers. Using the comprehensive rate and tariff database provided by our Signal API, Ford has been able to build new features that help EV drivers save money on charging.

When Ford began selling electric vehicles (EVs), they recognized the need to support new EV owners beyond the dealership. They knew the home charging experience would raise a lot of questions — for instance, when is the cheapest time of day to charge an EV? — and they wanted to help their drivers better navigate this new experience.

That meant Ford needed access to comprehensive electricity tariff data.

The company had an existing database of electricity tariffs, but it was difficult to maintain and was not comprehensive enough. That’s when Ford started to look for an external partner to provide the data needed to enable new charging features.

Signal solved an important problem for us. 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.


Ford’s team selected our Signal API as its replacement solution. Signal provides Ford access to the world’s most comprehensive utility price database with information from more than 2,000 utilities and 16,000 rate plans, covering more than 95% of all available rates in North America. The API captures every rate component, tariff eligibility rule, and rate option, and supports flat consumption rates, tiered and time-of-use (TOU) pricing, system and dynamic peaks, complex ratchets, and sophisticated billing rules.

Signal maintains the current electricity market and hourly retail pricing, including 15,000 tariff rate updates every month. With that level of data, Ford can enable new features that can help drivers save money on home charging.
