# EV Infotainment UI (Demo Project)
|
||
|
||
This project is a mock EV infotainment system built with React + TypeScript + Vite, designed to simulate how an in-car display could show battery State of Health (SoH) and charging session history.
|
||
|
||
|
||
|
||
It includes:
|
||
|
||
- A charger simulator API (mock backend)
|
||
- A beautiful infotainment-style UI
|
||
- A fixed 21:9 car-like viewport
|
||
- A bottom navigation bar fixed within the screen
|
||
- Smooth scrolling and EV-inspired design elements
|
||
|
||
This UI is intended for demo purposes as part of a larger system where: Charger → Backend → Infotainment UI (charger sends charging data → backend calculates SoH → UI visualizes last 30 days).
|
||
|
||
## Features
|
||
|
||
### Battery Health Visualization
|
||
|
||
Live SoH reading for the latest charging session
|
||
|
||
Change vs previous session
|
||
|
||
Temperature, SoC, and energy added summary
|
||
|
||
### Trend Chart
|
||
|
||
- 30-day SoH trend displayed with a custom SVG line chart
|
||
- Session points rendered with minimal dependencies
|
||
|
||
### Charging History
|
||
|
||
- Scrollable list of all charging sessions
|
||
- Shows SoH, Δ vs previous, and energy added for each session
|
||
|
||
### Infotainment-Style UI
|
||
|
||
- Status bar with icons (time, temperature, connectivity)
|
||
- Quick control strip (AC, night mode, eco mode – static)
|
||
- Bottom navigation menu (Home / Battery / Trips / Settings)
|
||
- Fixed 21:9 viewport with realistic bezel and rounded corners
|
||
|
||
### Mock Backend
|
||
|
||
- Generates realistic charging history for the last 30 days
|
||
- SoH degrades slowly over time
|
||
- Used when VITE_USE_MOCK_API=true
|
||
|
||
## Tech Stack
|
||
|
||
- React (with TypeScript)
|
||
- Vite
|
||
- CSS only
|
||
|
||
## Getting Started
|
||
|
||
1. Install dependencies
|
||
|
||
```bash
|
||
npm install
|
||
```
|
||
|
||
2. Run in mock mode
|
||
|
||
Create a .env file:
|
||
|
||
```ini
|
||
VITE_USE_MOCK_API=true
|
||
```
|
||
|
||
Then start the dev server:
|
||
|
||
```bash
|
||
npm run dev
|
||
```
|
||
|
||
The infotainment UI will open at `http://localhost:5173/`.
|
||
|
||
3. Using a real backend (optional)
|
||
|
||
Set:
|
||
|
||
```ini
|
||
VITE_USE_MOCK_API=false
|
||
VITE_API_BASE_URL=https://your-backend.example.com
|
||
```
|
||
|
||
The UI will fetch real session data from the backend.
