Product Description
Overview
TG-0105 is a 1.44-inch TFT digital battery state-of-charge (SOC) gauge, with a 128 × 128 display, a 0–100% measurement range, and a red low-charge alert at or below 10%. TG-0105-001 uses the SAE J1939 CAN Bus protocol to read SOC data directly from the battery management system (BMS) or ECU. Typical applications include hybrid vehicles, electric vehicles, electric forklifts, and electric construction equipment — for battery condition monitoring and power management. Available for OEM / ODM design development and aftermarket use, and designed for Hybrid and EV Vehicle platforms.
