Centrica Plc, which operates one of the UK’s largest electric van fleets, has found a unique solution to the major issue of ‘bricking’ faced by EV fleets nationwide.

The problem occurs when the 12V auxiliary battery, which powers essential functions such as central locking, fails – leaving the vehicle completely inoperable.

The widespread issue typically happens when the vehicle is left unused for a couple of weeks, but the Association of Fleet Professionals (AFP) warned earlier this year that some fleets were having vehicles delivered in this state.

Normally, affected vehicles are impossible to start or recharge and have to be transported via trailer to a dealership, but Centrica has found a simple and effective solution that it’s rolling out across its 2,500-strong eLCV fleet to prolong battery life and keep its engineers on the road.

The company has teamed up with fleet technology specialist Genie Insights to fit solar panels to the roof of its electric vans. The panels provide a trickle charge to the 12V batteries, keeping them operational even during periods of inactivity, or when a so-called ‘parasitic draw’ is being taken by telematics or other ancillary equipment.

The panels are constructed using CIGS (copper indium gallium selenide) technology, and are lightweight, flexible and durable, as well as discreet, making them ideal for commercial vehicle applications.

They’re also said to be the only CIGS panels manufactured in the UK and the panel for this application has been specifically designed, tested and proven to generate the optimal voltage to maintain the battery’s charge.

After investigating various other options, Centrica said the technology was a clear frontrunner, ensuring the smooth and reliable running of its electric fleet and furthering its customer commitment to operational excellence.

Centrica’s director of fleet Rob Simister said: “Vehicle downtime is bad for business, and it’s bad for our customers. We had to find a solution quickly so that we can make sure our engineers can get to our customers exactly when we’re needed most.”

Matt Reeve, managing director of Genie Insights, added: “By taking this proactive approach to battery maintenance, Centrica is not only pioneering a solution to a widespread issue for fleet operators, but also solidifying its leadership in the UK’s transition to electric vehicles.”
