DC Quick Charger Reliability Is Important For Mainstream Adoption of Electrical Autos


A new examine on the reliability of DC quick chargers within the San Francisco Bay Space gives some a lot wanted information and unbiased evaluation to assist maintain EV charging networks accountable to a better degree of charging buyer expertise.

The Reliability of Open Public Electrical Automobile Direct Present Quick Chargers examine by UC Berkeley with help from Cool The Earth, SLAC Nationwide Accelerator Laboratory, and GISMo Group, revealed what most trade observers and EV drivers already knew — that utilizing public DC quick chargers is commonly a irritating and less-than-ideal expertise. The examine enlisted 20 volunteer EV drivers in testing “open” (which means no Tesla Superchargers have been examined) 657 DC quick EVSE (chargers) at 181 charging stations (charging areas) within the San Francisco Bay Space. The autos used for testing have been the Chevy Bolt, Kia Niro, Hyundai Kona, Ford Mustang Mach E, and Porsche Taycan. 

The researchers weren’t capable of cost at 23% of the DC quick chargers, which means that greater than 1 out of each 5 charging makes an attempt was unsuccessful. Causes ranged from damaged connectors to pay system and cost initiation failures.

However EV drivers don’t care what’s the explanation for the lack to cost their EV. It makes little distinction if it’s a {hardware}, software program, or mobile connection challenge, a damaged connector, an EV or ICE car parking however not charging, or the charger merely unavailable as a result of restricted hours of operation. This degree of failed charging makes an attempt is solely unacceptable.

Whereas chargers from a complete of 9 charging community firms have been evaluated, three charging networks, ChargePoint, Electrify America, and EVgo accounted for 97.3% (639 of 657) of the DC quick chargers evaluated. 

Amongst these three main charging networks it was really not stunning that chargers from ChargePoint had the very best proportion of charging points. Why? The important thing cause I consider is that whereas ChargePoint payments itself as a charging community it’s enterprise mannequin is definitely very completely different from many of the remainder of the charging networks — typically known as “cost level operators” — together with Electrify America and EVgo.

Most, however not all, of the key charging networks usually personal and function their charging areas and gear. ChargePoint, nonetheless, sells it’s charging {hardware} and on-line reporting information providers to website hosts equivalent to motels, eating places, and retail shops. The distinction in these enterprise mannequin approaches will be important as within the different charger working fashions by Electrify America and EVgo, for instance, they’re answerable for the general charging buyer expertise of the EV driver.

Within the case of a restaurant or resort proprietor that purchases ChargePoint gear and providers, the resort or restaurant proprietor and employees are literally answerable for managing the charging gear, upkeep, buyer expertise, and resolving any points. The truth is that the day supervisor at a resort or a restaurant supervisor is aware of little-to-nothing about EV charging and are ill-equipped to ensure the gear works, connectors aren’t damaged, and software program is up-to-date.

To be clear, ChargePoint shouldn’t be the one responsible occasion throughout the EV charging ecosystem, nonetheless, the UCB examine underscores that the charging networks more and more should be extra like fuel stations the place a single entity is answerable for the reliability of the charging gear and resolving any buyer expertise points.

More and more, federal and state grants, incentives, and loans would require a sure degree of uptime and reliability that could be verified by third-party audits. Charging suppliers that can’t present they may meet these uptime necessities is not going to qualify for funding. And people authorised that can’t preserve uptime minimums could also be assessed penalties, have funding {dollars} reversed, or the charging websites transferred to a unique supplier.

A dependable EV charging expertise is prime to EVs changing into mainstream in America. It’s no accident that Tesla dominates EV gross sales within the US and can proceed to take action for a few years to come back. There are various contributing elements to Tesla’s US gross sales success, however arguably its largest aggressive benefit from a driver’s perspective is a mixture of the corporate’s Supercharger DC quick charger and Stage 2 Vacation spot Charging networks.

However so long as this particular or perceived chasm exists between the Tesla charging expertise and that of homeowners of different EV manufacturers and customers of non-Tesla EV charging networks — many shoppers will select to purchase a Tesla EV merely as a result of a greater charging expertise. This doesn’t simply lead to a better market share of EV gross sales for Tesla, however it implies that many “on-the-fence” shoppers who could not need to purchase a Tesla, will merely select to not buy an EV altogether and go for one other ICE car.

In an upcoming article I’ll share the entire components that must be included in a complete charging buyer expertise framework.
