How Mercedes-Benz's Charging Network Is Tackling The Awkward Transition To NACS

Mercedes-Benz High-Power Charging just came up with an elegant solution for the transition phase: multiport chargers with four cables per unit (two NACS, two CCS) so any EV can pull up and charge without an adapter.

Each Alpitronic HYC 400 delivers up to 400 kW, and Mercedes is retrofitting its entire network with these units. About half of their 30 stations already have them, and all future locations will be multiport-only. It's one of the smartest ways to handle the CCS-to-NACS transition without leaving anyone behind — no adapters, no confusion, just plug in and go.

This Ultra-Fast EV Charger Can Go Online Much Faster

ElectricFish just unveiled a DC fast charger that could solve one of the industry's biggest headaches: grid upgrades. Their new charger delivers up to 400 kW without requiring costly electrical infrastructure improvements, which typically add months to deployment timelines. This could be a game-changer for accelerating the rollout of high-power charging stations in places that desperately need them but can't justify the expense of rewiring the grid. If ElectricFish can scale this technology, we might finally see ultra-fast chargers pop up as quickly as gas stations did decades ago.

Tesla's White-Label Supercharger Program Adds Another Customer

Francis Energy just became the latest company to open a Tesla-branded charging site under the program Tesla launched a few months ago.

The first Francis Energy location in Norman, Oklahoma, features 4 stalls with 325 kW charging and Magic Docks for non-Tesla EVs at $0.44/kWh.

Tesla Model Y Gets 7-Seat Option, New Wheels, and Black Interior in U.S. Refresh

The refreshed Model Y just got a few notable upgrades for U.S. buyers. For $2,500, you can now add a third row to the Premium AWD trim. Along with it, Tesla has made other changes aligned with updates in China: a sleeker black headliner on Premium and Performance trims, a larger 16-inch center touchscreen, matte black badging across all versions, and new dark gray 20-inch wheels for $2,000.

High-Power Fast Charging Is The Leading Cause For EV Battery Degradation

A new study of over 22,700 EVs across 21 models found that frequent use of 100+ kW fast chargers significantly speeds up battery degradation. EVs that rarely fast charge see about 1.5% annual degradation, while those hitting high-power chargers more than 40% of the time experience 3.0% degradation — double the rate.

The study also reveals that average degradation rates have climbed from 1.8% in 2023 to 2.3% in 2025, likely because high-powered charging stations are now everywhere across North America. Fast charging is convenient, but your home charger should be your primary source of energy.
