Smart Charging

The Problem

Why does this extension exist?

Electricity prices vary by 10x between peak and off-peak hours. Solar production fluctuates. Grid capacity has limits. Operators who charge blindly pay far more than they need to. Smart charging turns energy cost into a competitive advantage.

The Solution

What you get

Multi-condition charging schedules: price below X AND solar above Y AND finish by 7 AM
Real-time spot price integration: Nord Pool, EPEX, OMIE - charge when electricity is cheapest, automatically
OCPP smart charging profiles: TxProfile, TxDefaultProfile, ChargePointMaxProfile
OSCP integration: receive capacity forecasts from Distribution System Operators
Solar surplus charging: only charge EVs when solar production exceeds site consumption
Recurring schedules: set once, runs every weekday automatically

🎯 Who is this for?

CPOs and fleet operators wanting to reduce energy costs, participate in demand response, or integrate with solar and battery storage.

Key Capabilities

Everything included

Spot Price Charging

Connect to Nord Pool, EPEX, or OMIE real-time spot prices. Chargers activate automatically when price drops below your threshold.

Solar Surplus

Charge EVs only when solar production exceeds site consumption. Zero grid import, zero energy cost.

Time-Window Scheduling

Set charging windows with finish-by targets. The system calculates the optimal start time to meet the deadline at minimum cost.

OSCP Integration

Receive capacity forecasts from your Distribution System Operator. Automatically reduce charging during grid stress events.

OCPP 2.0.1 Profiles

Full OCPP 2.0.1 smart charging profile support. Works with any compliant charger.

Recurring Schedules

Set once, runs automatically. Weekday schedules, weekend schedules, seasonal adjustments.

Use Cases

See it in action

How operators around the world can use this extension to solve real problems and grow their business.

Office car park charges fleet at spot price

A company with 20 EVs sets a schedule: charge when spot price is below 0.08 EUR/kWh, finish by 7 AM. The system monitors Nord Pool prices in real time and activates chargers during cheap overnight windows. Average energy cost drops from 0.18 to 0.09 EUR/kWh.

Solar-powered site eliminates grid import

A supermarket with 100 kW solar panels sets solar surplus charging. EVs only charge when solar exceeds store consumption. In summer, 80% of EV charging energy is free solar.

Grid operator sends OSCP capacity event

The local DSO sends an OSCP capacity forecast: maximum 50 kW available 17:00-19:00. OASIS HUB automatically reduces all chargers to 25% power during the window. The operator avoids grid penalty fees.

Simulated Case Study

Fleet depot reduces EV charging energy costs by 52%

A logistics company with 40 EVs was charging during business hours at 0.22 EUR/kWh average. After enabling Smart Charging with Nord Pool spot price integration, the system shifted 75% of charging to overnight hours when prices average 0.09 EUR/kWh. Combined with solar surplus charging, the average energy cost dropped to 0.11 EUR/kWh. Annual savings: 28,000 EUR.
