Improving Reliability Across 16 Workplace EV Charging Stations
The Challenge
A local business operating 16 workplace EV charging stations for employees and visitors was experiencing recurring reliability issues.
Whilst the charging units themselves were generally functioning correctly, connectivity problems meant chargers were frequently showing as offline on the management platform. This created frustration for users who had made the switch to electric vehicles and relied on the charging infrastructure throughout the working day.
As workplace charging becomes increasingly important for staff and visitors, reliability and consistency are essential.
Our Investigation
Following the award of the maintenance contract, our team undertook a detailed review of the charging infrastructure and associated communications network.
Most commercial EV charging stations rely on an internet connection to communicate with management platforms, process charging sessions, provide reporting data, and allow remote monitoring. These connections are typically achieved via either:
- Hard-wired network connections
- Mobile network communications
Our assessment identified connectivity as the primary cause of the ongoing operational issues.
The Solution
Working closely with the client, we implemented a programme of improvements which included:
Upgrading selected EV charging stations
Introducing a more robust communications strategy using a combination of hard-wired and mobile network connectivity
Establishing a planned monthly maintenance and inspection programme
Carrying out routine operational checks to identify potential issues before they could impact users
The Results
Since implementing the improvements and planned maintenance regime, charger availability and reliability have significantly improved.
The client now benefits from:
- Greater charger uptime
- Reduced connectivity issues
- Improved user experience for staff and visitors
- Proactive identification of developing faults
- Increased confidence in the EV charging infrastructure
Most importantly, employees who depend on workplace charging can do so with confidence, knowing the system is being actively maintained and monitored.
Why Preventative Maintenance Matters
EV charging infrastructure is becoming a critical building asset.
Whilst many organisations focus on repairs when faults occur, preventative maintenance helps identify potential issues before they develop into costly breakdowns or periods of downtime.
Regular inspection, testing and monitoring ensure charging assets remain safe, operational and capable of supporting both current and future EV users.
