In traditional testing methods, such as using real batteries or simple DC power supplies and electronic loads to test BMS and complete electronic systems, there are often challenges including low efficiency, high costs, safety risks, and limited testing scenarios. With the widespread adoption of high-rate battery cells in electric vehicles and consumer electronics, there is a growing demand for battery cell simulators capable of handling higher currents during product testing. The IT2700 series Multi-channel Modular Power System, combined with various bidirectional DC source modules, provide a more efficient and flexible multi-channel system integration solution.

1. Battery Management System (BMS) Testing

Charge and Discharge Management Strategy Testing:
The IT2700 series Multi-channel Modular Power System can simulate single cells or multiple cells to verify whether the BMS protection logic responds accurately and promptly under abnormal conditions such as overcharge, over-discharge, overcurrent, and short circuit.

Balancing Function Testing:
With its multi-channel capability, the IT2700 can simulate inconsistencies among cells within a battery pack (such as voltage differences). This allows engineers to test whether the BMS passive balancing or active balancing functions operate effectively.

Communication Function Testing:
When used with dedicated host computer software, the IT2700 can communicate with the BMS while simultaneously simulating battery voltage and current, enabling automated testing.

2. Standby Performance Testing for Consumer Electronics

Standby Time Testing:
The IT2700 features a built-in battery simulation function, allowing parameters such as open-circuit voltage, full-charge voltage, internal resistance, and rated capacity to be configured. The output voltage changes according to the state of charge, providing more realistic power supply conditions during typical device operating cycle tests and enabling accurate verification of standby performance.

Battery and Other Component Testing:
The IT2700 can perform battery charge/discharge characteristic curve testing, battery cycling tests, charger testing, and power supply discharge tests. Its multi-channel architecture, combined with modules such as electronic loads, SMUs, and other modules, can meet diverse testing requirements and significantly improve R&D testing efficiency.

Key Features of the IT2700 Series

1. Modular Design:
Supports a variety of modules—including DC sources, regenerative loads, bidirectional sources, and SMU modules—to meet diverse testing requirements across different industries, such as high current or high-precision applications. The 1U frameless chassis IT2702 can accommodate up to four 500 W bidirectional source modules, with each channel independently controlled and electrically isolated.

2. High-Precision Simulation and Professional Testing Functions:
The IT2700 Multi-channel Modular Power System come standard with built-in battery models, allowing seamless simulation of battery charge and discharge cycles. The SMU modules offer nanoamp-level precision far beyond ordinary power supplies, with seamless range switching, providing high-accuracy solutions for low-power applications such as smart wearables and medical electronics.

3. Flexible Series and Parallel Capability:
The IT2700 Multi-channel Modular Power System features a flexible dual-master master-slave parallel capability. Master-slave parallel operation enables current and power expansion. For simulating series-connected cells, users can physically connect modules in series while each channel operates independently with battery model functions, as long as the total working voltage does not exceed 600 V.

The IT2700 Multi-channel Modular Power System family is ideal for applications such as IoT terminals, chip power supply testing, automotive electronics, and smart wearables. It helps engineers gain deep insights into startup waveforms, transient responses, and power consumption characteristics, comprehensively improving testing efficiency and accuracy.
