EV Cost Settings — Charging Cost, Battery Capacity & Recharge Actions

EV cost settings let Speedometer 55 estimate electric-vehicle running cost, translate battery energy into remaining driving range, and record full or partial recharges more realistically.

In the app, these are the EV variant of the cost and fuel settings screen. They appear after you switch the cost type to EV.

Best for

• EV drivers who want cost per mile or kilometer based on real charging price
• users who want the driving range monitor to reflect remaining battery energy
• users who want the app to distinguish wall energy from battery energy

Choose EV cost settings

Choose EV cost settings when your vehicle is electric and you want the mileage calculator or range monitor to use battery capacity, charge price, and charging efficiency instead of fuel tank and fuel volume assumptions.

Choose standard fuel settings

Use the standard fuel cost settings instead when the vehicle uses gasoline, diesel, LPG, or another combustion fuel. Those setups depend on tank capacity, fuel volume, and fuel price rather than battery energy and charging efficiency.

What you get

• cost-per-distance estimates based on Price per kWh
• remaining-charge tracking for the EV range monitor
• a configurable Full recharge, kWh baseline
• support for Mark battery as full, Set charge, and Add charge
• EV-specific details such as Charging efficiency and Charging plug placement

EV cost parameters

Price per kWh is the charging price used for cost calculations. Use the blended price you actually pay most often, or update it when you want trip-cost estimates for a specific charger.

Full recharge, kWh is the usable battery energy treated as a full charge in the app. This should reflect the practical energy available for driving, not only the marketing battery size.

Driving range is the full-charge distance the app uses to translate remaining energy into remaining distance.

Charging efficiency, % tells the app how much wall energy becomes stored battery energy. This matters both for cost math and for the Add charge action. If you add 20 kWh of wall energy at 90% efficiency, the app stores it as 18 kWh of battery energy.

Charging plug placement only affects the on-screen hint shown next to the energy indicator.

Distance unit controls whether EV range and reimbursement values are interpreted in miles or kilometers.

Reimbursement per mile or Reimbursement per km is optional. Use it when you want trip reports or planning views to compare reimbursement against EV running cost.

Recharge actions

The EV charge menu separates three different actions because they represent different real-world situations:

• Mark battery as full resets the remaining charge to the configured full-recharge value.
• Set charge stores the current remaining battery energy directly. Use this when you know the battery state now.
• Add charge records a charging event by adding wall energy to the current battery state.

Add charge is the main EV-specific action. The value you enter is wall energy in kWh, and the app converts it to stored battery energy using Charging efficiency, %. This keeps both cost and remaining-range calculations realistic after partial charging stops.

Good first setup

• Enter the charging price you most commonly pay.
• Set Full recharge, kWh to your practical usable full-charge energy.
• Set Driving range to the distance you normally get from that full charge.
• Leave Charging efficiency near 90% unless you have a better measured value.
• Use Mark battery as full after a real full charge, then use Add charge for later top-ups.
