What EV Opticharge does
EV Opticharge is a practical EV charging calculator for home charging decisions. Enter your current battery level, target level, available time, vehicle battery size, voltage, charging phase, and efficiency assumptions to estimate the charging current needed to reach your target.
EV Opticharge is designed without online accounts, advertising, analytics, cloud sync, or behavioural tracking. It does not send usage logs or app activity to Railburn.
Home-power assumptions
Adjust voltage, single-phase or three-phase charging, efficiency assumptions, and vehicle battery size.
Clear local calculations
See practical estimates without needing an online account, cloud-connected charger, or remote calculation service.
Important limits
EV Opticharge provides estimates only. Actual charging behaviour depends on your vehicle, charger, electrical installation, battery conditions, and local power limits. It is not electrical, safety, financial, tariff, or energy-market advice.
Availability
EV Opticharge is in development. The public store link will appear here when it is available.
