About Joulo

What Joulo does and who builds it

The mission

Accelerating the transition to electric driving.

Everything we build serves that one sentence. Electric driving should be beautiful and easy. EREs are the start: automatic registration, every sale published and a 20% service fee with no small print. Then comes the rest of charging: sharing, smart charging and charging points that we operate.

Platform

Payment infrastructure for EREs

Joulo works like a payment platform: you connect once, then everything runs by itself. We read your charging sessions, register them with the NEa and pay out every quarter.

Direct connections

We connect your charger directly through the manufacturer's API or via OCPP. You never submit meter readings again.

Every kWh recorded

We record every kWh, check it and convert it into EREs. You see every step in your dashboard.

Sales and payouts

We sell the EREs in tranches across the year via brokers and pay out every quarter. Every sale is in our open sales ledger.

What Joulo stands for

Automation

Connect your charger and forget Joulo exists • until money lands in your account every quarter.

Accessibility

Large companies have earned from this scheme since 2015. Since 1 January 2026 every home charger can take part. You connect, we handle the rest.

Community

Joulo grows because customers refer new home chargers. Every active referral lowers your service fee. The terms are on the referral page.
