Charger reliability demonstrated by Kempower data, indicating a nearly constant 99% uptime, while user errors highlighted as a significant hurdle

Kempower's EV charging network has shown strong technical reliability, with an average Operational Success Rate (OSR) of 84.6% and a Technical Success Rate (TSR) of 94.3%. However, the network also faces challenges in the realm of user-related issues.

The OSR, which combines TSR and Usability Success Rate (USR), reflects the total percentage of successful charging attempts. Kempower's top-performing operators have a USR of 91.2%, indicating significant room for improvement.

Technical issues in the network include hardware or software problems such as plug-locking issues, charger malfunctions, and vehicle communication errors. On the other hand, usability failures are four times more common, with authentication problems being the most frequent issue.

Other common usability issues include forgotten plug connections and abrupt session stops. To address these challenges, Kempower has focused on simplifying authentication processes and improving user interfaces. This focus has led to significant usability enhancements, boosting the USR.

In addition, Kempower has achieved a reduction in plug-locking failures by 10%, thanks to design enhancements and user education. The company's commitment to data-driven solutions and collaboration with EV manufacturers positions it as a leader in the push towards a dependable, user-friendly EV charging ecosystem.

Moreover, Kempower's network maintains an average uptime of over 99%. This high uptime, combined with the ongoing efforts to improve usability, offers a roadmap for addressing shortcomings and enhancing reliability as networks continue to expand.

It's worth noting that, as of the available data, the EV charging station manufacturer with an average operational uptime of over 99% and a high average overall success rate for charging attempts is not explicitly identified.

Lastly, Kempower has taken measures such as software fixes and vehicle recalls in collaboration with EV manufacturers to resolve communication errors. These steps, along with the ongoing focus on usability, are crucial for achieving higher overall success rates in the EV charging industry.
