Key Features
Smart Cost Optimization
- Automatic Slot Finding: Analyzes today's and tomorrow's electricity prices to find the cheapest charging windows
- Grid Price vs Effective Cost: Shows both what you pay for electricity (grid price) and the actual cost per kWh in your battery (accounting for charging efficiency losses)
- Flexible Charging Windows: Supports multiple charging sessions (e.g., charge during 3 cheapest periods) or single continuous sessions
- Time Constraints: Set a "complete by" deadline to ensure your vehicle is charged when you need it
Interactive Controls
- SOC Slider: Drag to adjust your target charge level on the fly and instantly see the updated charging plan
- Complete By Controls: Click the time to expand adjustment controls with intuitive buttons (⏪⏴⏵⏩) for 15-minute intervals
- Visual Feedback: Color-coded slider shows different charge ranges (current SOC, target range, high charge, maximum)
Automation Integration
- Program Charging Button: Send the calculated charging plan directly to your EV or EV charger via Home Assistant scripts/automations
- Structured Data: Receives complete charging schedule with ISO timestamps, energy amounts, costs, and SOC levels
Charging Efficiency Support
- Account for Losses: Configure separate "energy in" (grid consumption) and "energy out" (battery charging) values to account for AC charging efficiency losses
- Accurate Cost Calculation: See both grid prices (what you pay) and effective costs (cost per kWh delivered to battery)
- Typical Efficiency: AC charging is usually 85-90% efficient; DC fast charging is 92-97% efficient
