30-95V 200A Battery Management System for Mini Electric Vehicles
The DTH2302 is a battery management system engineered for mini electric vehicles, low-speed four-wheelers, and sightseeing vehicles. It operates on a 30–95V voltage platform with 15S–24S cell configurations and works with NCM, LMO, LCO, and LFP chemistries. With 200A continuous discharge and a 400A peak for 30 seconds, it supports light-power traction packs that require steady current delivery plus short bursts during acceleration or climbing.
DTH2302 — 110mm × 255mm × 47mm enclosure with RS485 ×2 and 6 external NTC channels.
Key Features
30–95V / 15S–24S Platform
One board covers 15S to 24S packs across a 30–95V range, so integrators can standardize on a single BMS across several vehicle models.
200A Continuous, 400A Peak / 30s
Delivers 200A continuous discharge with 400A peak handling, matching the acceleration and grade-climbing demands of light electric vehicles.
6 External NTC Channels
Six external temperature sensing inputs monitor cell and pack heat, supporting operation across a −30°C to 85°C range.
RS485 ×2 and Platform Connectivity
Dual RS485 ports, with selected models linking to APP, PC, IoT platforms, or displays for vehicle monitoring and software expansion.
SOC / SOH / SOP within ≤8% @25°C
State estimation accuracy of ≤8% at 25°C helps drivers and fleet operators read remaining range and pack health with confidence.
Passive Balancing ≥50mA @25°C
Balancing current of at least 50mA at 25°C, plus insulation detection from 0–20MΩ, supports pack longevity and electrical safety checks.
