Data Items

Using telematics devices, cars can distribute data for many purposes for an end-user. Car data is created by electrical sensors linked to the ECU or Electronic Control Unit. An ECU is linked to an onboard telematics device which transmits live data. A user in a central location receives this data over the air, with an end interface that can be configured in a way that works for their business.Many attributes of a car can be transmitted live or at set intervals using GPS and mobile data networks.

Using car data, fleet management companies analyse their vehicles to help reduce costs, prevent maintenance issues and schedule service appointments in advance. Governments and councils can use car technical data to better manage traffic. Insurance companies can have real-world use cases for their customers and the introduction of smart cities with connected cars results in more efficient infrastructure. Most importantly, emergency services receive live vehicle data to accurately locate an accident, with automatic triggers to call ambulances if the vehicle senses it is in a severe accident.

What Is Charger Voltage Data?

Whether using a home charger via a wall box or conventional outlet, DC fast charger or rapid charger, voltage data is required to allow the functioning of the charging system. It is used for many other attributes to work in an electric vehicle. These include estimated time to charge, AC/DC conversion and to help manage temperatures and safety of charging systems.

The data from voltage sensors on an electric vehicle are fed into a vehicle telematics unit and control modules within the external charger. They transmit charger voltage data using mobile networks for remote monitoring by an energy supplier, card payment issuer, fleet management company and the electricity grid for many uses.

Use Cases

Many stakeholders are involved in the voltage data. As it is a safety-critical component, charging systems must communicate correctly with the vehicles they are charging. Data can be transmitted to a central fleet manager to understand if the charger being used is working correctly. Fleets can monitor the charge level on each of their vehicles too. With the rate of charging measured as kW, charging voltage data is used in this kW calculation and in turn, can calculate when the battery is fully charged.

This voltage data can be analysed by charger suppliers to work out any safety issues or maintenance required for their units. It can be used to correlate what speed the car is charging at against what the charger unit is saying to the user.
