Chevrolet Bolt EV vehicle data API: signals, model years and connection options

Get API keys →

DIMO gives developers API access to Chevrolet Bolt EV vehicle data. Model years 2017 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include odometer, current charge level and vehicle speed.

DIMO provides a vehicle data API for the Chevrolet Bolt EV through a DIMO device, covering model years 2017 and newer. DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. Coverage for this model is tested rather than expected. DIMO adds vehicle-state depth on top of GPS tracking; it doesn't replace it.

No factory connectivity?

Chevrolet Bolt EV model years 2017 and newer have no OEM cloud connection listed. For these years, a DIMO device (DIMO LTE R1 or AutoPi) plugs into the OBD-II port and streams vehicle signals once the owner connects it and consents to sharing.

See the developer quickstart for how owners connect vehicles and grant access.

Events available

  • Recharge
  • Harsh braking

Build it

Query the latest Chevrolet Bolt EV signals with the DIMO TypeScript SDK. The vehicle owner must first share access with your app through DIMO Connect.

import { DIMO } from '@dimo-network/data-sdk';


const dimo = new DIMO('Production');
const tokenId = Number(process.env.DIMO_TOKEN_ID); // from DIMO Connect


const developerJwt = await dimo.auth.getDeveloperJwt({
  client_id: process.env.DIMO_CLIENT_ID,
  domain: process.env.DIMO_REDIRECT_URI,
  private_key: process.env.DIMO_API_KEY,
});
const vehicleJwt = await dimo.tokenexchange.getVehicleJwt({
  ...developerJwt,
  tokenId,
});


// Latest Chevrolet Bolt EV signals
const data = await dimo.telemetry.query({
  ...vehicleJwt,
  query: `
    query {
      signalsLatest(tokenId: ${tokenId}) {
      powertrainTransmissionTravelledDistance {
        value
        timestamp
      }
      powertrainTractionBatteryStateOfChargeCurrent {
        value
        timestamp
      }
      speed {
        value
        timestamp
      }
      }
    }`,
});
console.log(JSON.stringify(data, null, 2));

FAQ

How do I track a Chevrolet Bolt EV with no connected services?

Use a DIMO device. Once the owner shares the vehicle with you, exchange your Developer JWT for a Vehicle JWT and query the Telemetry API. The segments query returns trip data for a maximum date range of 31 days.

How do I detect recharging on a Chevrolet Bolt EV?

The recharge event is listed for both the DIMO LTE R1 and AutoPi devices. Query the Telemetry API segments resource with the recharge detection mechanism, which uses charging signals and state of charge.

How do I detect harsh braking on a Chevrolet Bolt EV?

The harsh braking event is listed for the DIMO LTE R1 device. Request HarshBraking in eventRequests on a segments query to get per-trip counts, or create a webhook on behavior.harshBraking in the Vehicle Triggers API to get notified when it happens.

How do I verify Chevrolet Bolt EV mileage?

A DIMO device on the DIMO LTE R1 reports the odometer signal. The Attestation API's odometer-statement endpoint generates a verifiable credential for the vehicle, which you can retrieve through the Telemetry API.

Which Chevrolet Bolt EV model years work with DIMO?

DIMO devices have been seen working on Chevrolet Bolt EV model years 2017 and newer. For older vehicles, contact DIMO for additional support.

Do I need hardware to get Chevrolet Bolt EV data?

Yes. DIMO lists no OEM cloud connection for the Chevrolet Bolt EV, so data comes from a DIMO device.
