New Energy Vehicle Battery Management System (BMS) Product Series

Product Specification

Feature

The DTH2302 Battery Management System is designed for mini electric vehicles and sightseeing vehicles. It supports a 30–95V voltage platform and 15S–24S cell configurations, compatible with NCM, LMO, LCO, and LFP chemistries. The system provides a continuous discharge current of 200A and a peak current of 400A/30s. It features 6 external NTC temperature sensing channels, operating from -30℃ to 85℃. Communication interfaces include RS485 ×2. Comprehensive protection functions cover over-charge, over-discharge, over-current, over-temperature, over-voltage, under-voltage, and insulation detection. Pre-charge function is supported. Wake-up methods include charge/discharge DET wake-up, charge wake-up, and RS485 wake-up. Heating function is supported with output voltage equal to battery pack voltage and current ≤6A. Insulation detection range is 0–20MΩ. The dimensions are 110mm * 255mm * 47mm. Passive balancing current is ≥50mA@25℃. SOC/SOH/SOP estimation accuracy is ≤8%@25℃, and up to 500 fault records can be stored. Selected models can connect with APP, PC, IoT platforms, or displays to support vehicle monitoring and software expansion. Customized PCBA and integrated hardware-software development can be confirmed against cell chemistry, series count, current, protocol, and operating conditions.
