EV Charger Uptime Report - Flipbook - Page 8
One of the main causes of EV charger outages is communication failures within the
charger itself. These failures can occur for a number of reasons, including software
bugs, hardware malfunctions, and network connectivity issues. When these failures
occur, the charger is unable to communicate with a CPO’s central management system,
which can result in the charger going offline and becoming unavailable to EV drivers.

EV chargers use complex communication systems to interact with the grid, the EV, and
the user. These systems may include network communication, cloud-based services
and mobile applications. However, these systems can be vulnerable to communication
failures, power outages, and software bugs. These failures can prevent EV drivers
from starting or stopping a charge, knowing the status of the charger, or paying for
the service. Often times the solution to this common communication failure can be a
simple re-boot of the charger itself.

In addition to the inconvenience caused to EV drivers, the widespread nature of public
EV chargers also presents challenges for the CPOs tasked with maintenance of the
charging infrastructure. With EV chargers located far apart from each other, it can take
a significant amount of time for a CPO’s maintenance technician to reach an offline
charger and reboot it. Furthermore, the maintenance force for EV chargers is not yet
large enough to adequately respond to outages in a timely manner, meaning it can take
several days or even longer for a technician to reach a site.

When these stations have poor communication,
or aren’t able to talk to the cloud, or had a
firmware update that is blocking it (the charger)
from making certain protocols, that’s when you
start getting into a lot of issues.
