Today, we’re excited to introduce the Smartcar EV battery capacity API. Starting today, Smartcar customers across North America and Europe can request early access to this new API endpoint.

Smartcar allows mobility apps and services to easily connect with their customers’ cars. Our new battery capacity API enables electric utility providers and EV charging networks to retrieve the total capacity from an electric vehicle’s battery.

Retrieving the battery capacity from an EV

With our new API endpoint, checking the battery capacity of a battery-electric vehicle (BEV) or plug-in hybrid vehicle (PHEV) is as simple as one API request:

Smartcar then returns the car’s battery capacity in kilowatt-hours (kWh):

Building and scaling EV charging solutions with Smartcar’s EV APIs

In addition to our existing EV battery level, EV charging status, and EV start/stop charge API endpoints, the new battery capacity API allows energy companies, electric utility providers, and EV charging networks to significantly improve and scale their EV charging products:

  • 🏡 Smarter, more accurate home charging solutions: Predict charging times and electricity costs for your customers more accurately based on their EV’s battery capacity.
  • 🔄 Better-informed demand response programs: Take the battery capacity of your customers’ electric vehicles into account when predicting and managing the load on your network.
  • ⚡ More efficient EV charging networks: Predict exactly how long your customer will need to fully charge at any station in your network, even when their vehicle is not currently plugged in.
  • 📍 Better EV trip planning: Know how long it will take your customer to charge at each charging station along their trip and calculate more precise ETAs.

Benefits of using Smartcar's electric vehicle API

When comparing Smartcar’s EV APIs to other solutions on the market, our customers benefit from the following advantages:

  • One platform for all EVs: Smartcar’s unified platform allows you to integrate with most EV models across 20 car brands in a single integration.
  • Extensive feature set: In addition to our extensive collection of EV APIs—which include state of charge, range, charging status, start/stop charge, and battery capacity—Smartcar offers a wide range of other API endpoints, from location and lock/unlock to odometer and tire pressure.
  • Friendly documentation and SDKs: As a software company, we deeply believe in a developer-first approach. Our friendly docs and SDKs allow your engineering team to integrate Smartcar in a breeze.
  • Available in your country: Our APIs are available in six countries across North America and Europe, with more markets coming soon. Our vehicle onboarding flow, Smartcar Connect, is available in three languages.

Starting today, Smartcar customers across North America and Europe can request early access to the Smartcar EV battery capacity API. If you aren’t a customer and would like to learn more about Smartcar, schedule a free product demo today.
