CAN bus interfaces

How do I read EV data from the CAN bus?

An EV CAN bus interface reads electric-vehicle data such as state of charge, range, charging state and high-voltage status from the vehicle bus, so converters and interlocks can respond to the state of the vehicle. These signals are built to order and available on enquiry.

Electric vehicles put a rich set of data on the CAN bus, from state of charge and range to charging state and high-voltage status. Converters, body builders and equipment installers increasingly need to read that data so their systems respond to the actual state of the vehicle. A CAN interface is how you get at it.

The signals that matter on an EV

State of charge and range let equipment behave sensibly around available energy. Charging state matters when equipment should behave differently while the vehicle is plugged in. High-voltage status matters for interlocks, so converters and body systems know when the vehicle is live and stay safe. The CAN KONTROL EV covers general EV data, the CAN KONTROL CHARGE focuses on charging state, and the CAN KONTROL HVSTATE targets high-voltage status for interlocks.

Built to order, available on enquiry

EV data varies a great deal between platforms, so we treat these as built to order, available on enquiry, rather than a fixed off-the-shelf list. What can be read, and how reliably, depends on the specific vehicle. Tell us the vehicle and the signal you need and we confirm what is possible and how we would deliver it.

These units are built on the i2CAN platform, designed and manufactured in the UK by Intellitec, part of Scorpion Group. One configurable platform covers the range, and on vehicles under warranty the bus can be read with a no-cut inductive reader.

What to tell us

Tell us the make, model and year, and exactly what your converter or interlock needs to know, whether that is state of charge, range, charging state or HV status. We confirm what can be read and configure it for the vehicle.

Frequently asked questions

Can you read state of charge from an EV CAN bus?
State of charge is one of the EV signals we work with. Availability depends on the specific vehicle, so we treat these as built to order, available on enquiry, and confirm what can be read from the bus for the vehicle you have.
What EV signals are you targeting?
The focus is on state of charge, range, charging state and high-voltage status. These support converters, interlocks and any equipment that must respond to whether the vehicle is charging or live.
Are these products available now?
These are built to order and available on enquiry rather than off-the-shelf. Tell us the vehicle and the signal you need and we confirm what is possible and how we would deliver it.
Why does HV status matter for a conversion?
Converters and body equipment often need to know the high-voltage state so they interlock correctly and behave safely. Reading HV status from the bus lets that equipment respond to the actual state of the vehicle.
