Case Study: Resolving EV Charger Communication Issue

Challenge: The EV charger was unable to communicate with Power meter 105. This communication failure could disrupt charging functionality and prevent accurate energy usage data collection.
Our Approach:

1. Problem Identification: The client reported an inability for the EV charger to communicate with Power meter 105.
2. Firmware Update: An engineer visited the site and updated the charger's firmware to version 6.6.2. This is a standard troubleshooting step for resolving communication issues.
   Outcome:
   • After the firmware update, the charger successfully established communication with the back office and displayed no faults. This indicates a successful resolution of the communication problem.
   Lessons Learned:
   • Outdated firmware can sometimes lead to communication issues between EV chargers and other components.
   • Regular firmware updates are crucial for maintaining optimal functionality of EV charging infrastructure.
   • A prompt response and efficient troubleshooting techniques are essential for minimising downtime and ensuring smooth charging operation.
   Note: This case study highlights the importance of preventative maintenance through firmware updates for EV chargers. By addressing communication issues promptly, service providers can ensure accurate energy data collection and uninterrupted charging experiences for clients.
