Some US charging stations will now stop EV owners from charging past 85%.

Some US charging stations will now stop EV owners from charging past 85%.

The shift towards electric vehicles (EVs) is gaining momentum, but the transition isn't without its challenges.

One major concern is the availability and accessibility of charging infrastructure. While charging networks are expanding, the situation on the ground reveals a significant chunk of these chargers are often inoperable or unavailable.

There's also the issue of EV drivers who occupy charging stations for longer than necessary, creating delays for others.

To tackle this problem, Volkswagen Group's Electrify America is introducing measures to penalise those who overstay their welcome, specifically those who charge their batteries beyond 85%.

The 85% rule

Electrify America will implement an 85% charge limit at 10 of its busiest charging stations in California. Once a vehicle reaches this threshold, power will be cut off. Drivers who don't unplug within 10 minutes will face an additional fee of US$0.40 (around NZ$0.60) per minute.

Robert Barrosa, president of Electrify America, explains that fast chargers aren't designed for topping off batteries. The final 20% of a charge takes significantly longer than reaching 80%, leading to inefficient use of resources and potential congestion.

Electrify America's initiative is not entirely new. Tesla has already implemented similar measures at some of its congested Supercharger stations. However, Tesla allows drivers to override the 80% charge limit if they need to.

Mixed reactions

While some applaud Electrify America's initiative, others raise concerns. Some argue that preventing drivers from fully charging their vehicles could create anxiety, especially for those embarking on long journeys or owning EVs with limited range.

Additionally, concerns have been raised about the availability of charging stations in certain areas. Electrify America acknowledges this issue and states that they are working on expanding their network. The company also assures that they are unlikely to impose a charging cap at stations near major highways.

Striking a balance

As the EV market matures, finding solutions that balance efficiency and convenience will be crucial. While preventing charge hogs is essential, ensuring access to adequate charging for all EV owners is equally important.

The 85% rule is a step towards optimising charging infrastructure, but it's likely not the final solution. Further innovation and investment in charging technology will be necessary to create a seamless and equitable charging experience for everyone.
