Increasing Charger Uptime with Resilient Infrastructure

Feb 07, 2023

Electric vehicle (EV) ownership is on the rise in the U.S., but consumer surveys suggest that the EV charging experience needs to improve to address the lingering concerns of buyers. EV owners are worried about being able to reach their destinations, according to J.D. Power’s 2021 Electric Vehicle Experience ownership study, which found that vehicle range is the top thing on owners’ minds. A Forbes survey made a similar finding in the summer of 2022, with 62% of respondents reporting that they “always” or “frequently” feel anxious about their vehicles’ ranges and adjust their travel plans to suit.

The U.S. Department of Transportation is trying to relieve consumer fears of becoming stranded on the road with a dead battery. The National Electric Vehicle Infrastructure (NEVI) program will begin distributing $5 billion in funding to ramp up the installation of public DC fast-charging stations across the country. The aim is to establish a network of chargers no further than 50 miles apart along key interstate corridors.

However, knowing that there is a charging station within the remaining range of the vehicle only relieves part of the fear for drivers. On the flipside of range anxiety is “charging anxiety.” Charging anxiety comes from knowing that even if you’re able to locate a charger — which may be tucked away in the corner of a parking lot with very little signage — and even if that charger isn’t blocked by another vehicle, it may be down or broken.

Knowledge Leads to Confidence

The Forbes survey found that 43% of respondents had encountered a broken public charging station. As a customer, imagine the frustration of pulling up to an inoperable charging station with just the slimmest margin of battery life remaining. The funding requirements for the NEVI program state that charging stations must be operable at least 97% of the time, which will be a significant challenge for operators. The requirements also state that charging stations must be capable of communicating their functional status via web applications to drivers on the road so they can make confident decisions about where to pull over and recharge when needed. To meet these requirements, charging operators will need to invest in well-designed technical solutions.

“Ultimately, operators need a system for remote control and monitoring of their charging stations. This will allow them to quickly trouble-shoot outages without rolling a truck.” - said Mark Seitz Senior Business Unit Manager of Franklin Electric. 

Uptime Assurance and Remote Capabilities

Remote monitoring and control capabilities were a major focus when developing the NexPhase™ Smart EV Switchgear, according to Seitz. Switchgear is the critical connection between charging-station equipment and the utility’s power supply. The transformers and circuit breakers in switchgear receive and distribute the incoming power and protect the facility from faults. NexPhase™ combines all of the necessary equipment into a single, prewired module to save on installation time and costs. It also includes a separate communications system to give operators remote monitoring and control capabilities.

If a charger goes down, a remote technician can first determine whether the facility is receiving power from the utility. If the cause is a utility outage, it won’t count against NEVI’s 97% uptime requirement, but without this visibility an operator has no way to confirm and validate the outage.


If utility power is available, the next step in assessing an inoperable charger is to cycle the power off and back on. Power cycling (much like resetting a home modem) fixes about 50% of charger outages. But without a remote method for doing this, operators would need to send a technician to perform the power cycle on site. The NexPhase™ Smart EV Switchgear allows operators to power cycle remotely which may allow them to get their chargers back online faster and save on truck rolls.

“EV charging is a very young industry, but the NEVI requirements are setting the bar for user experience,” Seitz said. “We designed the first purpose-built switchgear for the industry with both the customer and operator experience in mind.”

EVs accounted for 5% of car registrations in the U.S. in March 2022, up from about 3% the year before, according to S&P Global Mobility data. But the gap between the aspirations and reality of EV adoption are still significant. The Inflation Reduction Act’s (IRA) recent extension of federal tax credits for EVs will continue to provide financial incentive to buyers, and automakers are rolling out more and more vehicle options every year. But the charging industry will be responsible for sorting out the final piece of the puzzle by providing EV drivers with reliable, worry-free charging experiences.
