Descripción
ITECH IT2600 Multi-channel Cell Simulator & Tester
The ITECH IT2600 Series is a high-precision, 1U multi-channel cell simulation and test platform. One unit integrates eight mutually isolated cell channels, each with independently programmable voltage, current and internal resistance. Built-in battery functions include 1st- through 5th-order equivalent-circuitmodels, an internal-resistance model, battery-curve simulation, fault simulation, and active/passive balancing tests.
Multiple ITECH IT2600 units can be connected in series for up to 200 channels and a safe total series voltage of 1200 VDC. The platform supports DC+AC sinusoidal voltage-ripple injection, open-circuit/short-circuit/reverse-polarity fault simulation, an oscilloscope, data logging, list programming, digital I/O, and CAN/LAN/USB interfaces for rapid integration into ATE and HIL systems.
Beyond conventional cell simulation, ITECH IT2600 also provides basic cell charge/discharge capabilities, including CV charging, discharging, cycling, capacity and energy calculations, and multiple cut off conditions. It supports workflows ranging from precision cell simulation and BMS validation to balancing tests, quiescent-current analysis, HIL integration, ATE production testing, and basic cell performance verification.

ITECH IT2600 Models
Voltage Ripple Simulation
Cell-level controlled sinusoidal ripple from 1 to 1000 Hz, up to 100 mVpp, with DC+AC output
Ripple simulation superimposes a controlled AC signal – typically sinusoidal – on the simulator’s DC cell-voltage output. This reproduces ripplegenerated in real battery systems by inverters, DC/DC converters and other power-electronic devices.The primary objective is to verify the abilityof the BMS front-end filter – including RC filtering and digital filtering algorithms – to reject ripple interference. This helps ensure accuratecell-voltage sampling under high-ripple conditions and reduces the risk of SOC estimation errors, false contactor actions and other safety-related responses.
BMS Coordinated
Voltage Ripple Simulation
From Coordinated Instruments to Comprehensive BMS Testing
One Software Platform, Three Test-Resource Categories
PV2600 centrally displays channel status and batch-configures voltage, SOC, internal resistance and battery models. Through unified test sequences, it coordinates ITECH IT2600, IT5241 and IT5240 so voltage, temperature and insulation conditions can change together, making complex BMS scenarios easier to configure, execute and reproduce.
- Centralized status display and batch settings for up to 200 channels.
- Unified sequencing across multiple instruments.
- Coordinated voltage, temperature and insulation changes
