lowBankOS V2G Aggregator Module – UI/UX Design 1. Onboarding & Enrollment Step 1: Install & Sign In – Users download FlowBankOS and authenticate via Google/Apple SSO (OAuth2) iphone.apkpure.com . Step 2: Add Charger – Prompt to scan the QR code on the charger or enter its serial number iphone.apkpure.com . If the charger supports V2G, the app highlights this capability. Step 3: Link EV – Ask the user to select their EV model from a list or connect via vehicle API (if supported). Explain that vehicle data (battery state, capacity) will be used only for V2G. Step 4: Agree to V2G Terms – Provide a clear explanation of flat charging fees, V2G feed‑in tariff, and any participation requirements. Visual elements: onboarding checklist, camera view for scanning, consent toggle. 2. Pricing & Incentive Dashboard Current Rate Card – Show a simple table: “Charging: $0.XX per kWh; Discharging (V2G credit): $0.YY per kWh.” Indicate whether prices vary by location (if dynamic tariffs exist). Incentive Wallet – Display accumulated points/credits from V2G participation or usage bonuses. Users can see how many credits offset future charging costs. Upcoming Events – Notify users of grid events (e.g. high‑demand periods) and potential bonuses for discharging during those windows. UI hints: Use colored badges for earnings vs cost; a mini bar graph comparing charging cost vs V2G credits. 3. Map & Hotspot View Interactive Map – A map tab showing chargers and aggregator hubs. Each marker displays: Charger name/location Availability status (idle/charging/discharging) Pricing per kWh (flat rate) and any surcharges/discounts V2G capability indicator (e.g. bolt symbol) Hotspot Overlay – A heat‑map layer highlighting areas with high grid demand (hotspots) or low‑cost zones. Color intensity signals potential earnings for discharging or cost savings for charging. Filters & Search – Filter by price, distance, V2G capability, power rating. Search bar for addresses or charger names. Details Drawer – Tapping a marker opens a panel with full details: connector type, power rating, cost per kWh, V2G credit, hours of operation, predicted wait time, and a button to start navigation or schedule. UX note: For EV owners, default filter could emphasize low‑cost locations. Use clear icons and color coding (e.g. green for cheap, orange/red for hotspots). 4. Session Control Start Charging/Discharging – Users can remotely start a charging or discharging session from the app. The control panel shows: Live metrics (kW draw, kWh delivered, duration) iphone.apkpure.com Earnings tracker – updates credits earned from V2G in real time Pause/Stop buttons Mode toggle for Standard/Eco/Boost charging speeds (Boost warns of high demand impacts). Pricing Summary – Display running cost/credit: “Charging cost so far: $1.40” or “V2G earnings: $0.70.” Under flat pricing, the cost per kWh remains constant, but the session total grows linearly. Notifications – Push alerts when the session completes or if the charger/vehicle goes offline. 5. History & Analytics History List & Calendar – Each session shows date/time, energy (kWh), cost, location, and points/credits earned. Users can filter by charging vs discharging sessions. Monthly/Yearly Summaries – Totals for kWh charged, dollars spent, kWh discharged, and dollars earned. Graphs highlight usage patterns and incentives. Export – Provide CSV/PDF exports for reimbursement or tax reporting. 6. V2G Earnings & Scheduling Earnings Dashboard – Summarise lifetime and monthly V2G credits. Show a breakdown by location and grid event participation. Schedule Discharge Windows – Users choose when to allow discharging (e.g. between 18:00–22:00). The app uses vehicle API or estimated battery state to ensure minimum state‑of‑charge remains. Set Minimum SOC – Slider to set the lowest battery level to maintain (e.g. 50%). The app will stop discharging when the SOC hits this threshold. Consent & Overrides – Each discharge requires user consent or pre‑authorization, with clear messaging about battery health and usage. 7. Multi‑Location & Sharing Home, Work, Public – Users can add multiple chargers/EVs and switch between locations iphone.apkpure.com . Points/credits aggregate across all devices. Shared Access – Owners can invite family members; each session logs the user ID, which ensures incentives are fairly allocated. Map Favourites – Users can mark frequently used chargers or preferred hotspots for quick access. 8. Advanced Settings Limit Current & Demand – For users concerned about peak demand charges, allow current limit settings (e.g. 6, 16, 32 A) iphone.apkpure.com . Show how limits affect charging time/cost. Firmware & Updates – Notify users when new features or V2G capabilities become available iphone.apkpure.com . Language & Accessibility – Support multiple languages iphone.apkpure.com , dark mode, and accessibility options. Summary of Key UI/UX Principles Transparency – Always show current cost per kWh and earnings per kWh. Users should know exactly how much they pay or earn. Guidance & Safety – Provide clear warnings when enabling Boost or V2G discharge, and require explicit consent. Gamification & Incentives – Tie usage and participation to points/credits. Highlight progress bars toward bonuses in the live session view. Interactivity – The map should be responsive, with zooming, filtering, and route planning. Hotspot overlays must be intuitive and color‑coded. Consistency – Use the same design language across modules: flat cards, clear icons, concise labels, and progressive disclosures. By incorporating pricing transparency, map‑based discovery, hotspot visualization, real‑time monitoring, and V2G earnings features, FlowBankOS can deliver a comprehensive EV owner module that rivals existing V2G aggregators and makes participation in grid services simple and rewarding.
