[Custom Card] Glass BMS Card – A sleek, glass-morphism style dashboard for your battery data

Hi everyone,

I’d like to share a custom Lovelace card I’ve been working on: Glass BMS Card.

I wanted a clean, modern way to visualize Battery Management System (BMS) data that fits perfectly into “Glassmorphism” styled dashboards. It provides a comprehensive overview of your battery’s health and state at a single glance.

:battery: Key Features:

  • Modern Design: High-quality glass-effect visuals with SVG-based rendering.
  • Detailed Cell Monitoring: Supports up to 16+ cells with individual voltage displays.
  • Dynamic SOC Visualization: Includes an animated charging indicator and a percentage bar/dot system.
  • Comprehensive Stats: Dedicated slots for Total Voltage, Current, Remaining Energy, Cycles, Temperature, and Cell Difference.
  • Multi-Language Support: Automatically adapts to your Home Assistant language settings (currently supporting English and German).
  • Alert System: Visual warnings for high cell voltage differences or system failures.

Hope all of you will enjoy
