Practical Notes: EX90 on Mercedes-Benz HPC
The EX90's CCS port plugs directly into Mercedes-Benz HPC's CCS stalls without an adapter. Check the Mercedes-Benz HPC app before your first session to confirm which connector your target station uses — mixed-connector deployments are common in 2026.
On a session-by-session basis, the EX90's 250 kW peak charging speed is well-matched to Mercedes-Benz HPC's DC fast hardware. Expect a 10→80% charge in roughly 15 min. Real-world times run 10–20% longer due to charging taper and battery preconditioning.
Cost-wise, one $35.52 full charge on Mercedes-Benz HPC represents $0.11 per mile of driving — about 11.5¢/mile. A gas equivalent at 30 mpg and $3.50/gal is roughly 11.7¢/mile, so this charging session is still cheaper than gas. Over 15,000 miles/year, exclusive reliance on Mercedes-Benz HPC would cost roughly $2,148.39/year in fuel — a meaningful delta compared to mostly-home charging (~$886.21/year).
For most EX90 owners, the realistic use-pattern for Mercedes-Benz HPC is road trips and occasional top-ups — not primary fueling. If you live in an apartment or condo and rely on public charging as your main option, factor in the per-session pricing with no membership option. For regular home charging in a specific state, check our home vs public analysis and your EX90 state-by-state breakdown.
