The BattPulse BMS Display 7" is a professional-grade 7-inch colour touchscreen display designed for real-time monitoring and control of battery management systems. It connects to any compatible BMS via CAN Bus or WiFi and shows pack voltage, cell voltages, temperatures, I/O states, faults and state of charge β€” all on a vivid 1024Γ—600 IPS panel with 5-point capacitive touch.

πŸ“Š
Real-Time Dashboard
SOC arc gauge, pack voltage/current, min/max cell, temperatures, I/O status, fault alerts β€” all refreshed at 100 ms (CAN) or 250 ms (WiFi).
πŸ”‹
Cell Voltage Grid
Individual cell voltages in a colour-coded grid. Supports 6S–16S packs, odd or even. Auto-adapts to your BMS cell count.
πŸ”Œ
Dual Connectivity
CAN Bus (500 kbps default, configurable) for wired installations. WiFi 2.4 GHz for remote/wireless monitoring. Use either or both.
βš™οΈ
Easy Configuration
On-screen settings with touch keyboard. Configure WiFi SSID/password, BMS IP, CAN IDs, baud rate, display brightness, screen timeout.
🌑️
8 Temperature Probes
Up to 8 temperature sensors displayed with auto-detection. WiFi mode shows BMS-defined sensor names (e.g. "ShuntTemp", "NTC_1").
πŸ›‘οΈ
BMS Control
Remote BMS restart via CAN with two-step safety protocol (ARM + EXECUTE). Prevents accidental commands. Screen restart button included.
