Battery Simulator: High-Precision Bidirectional Power Testing
Release date:
2026-10-30
Battery Simulator provides precise bidirectional power control for battery testing, charging, discharging, and reliable energy system development too.
Flexible Testing for Battery and Energy Systems
As battery technology and energy storage systems continue to develop, reliable testing equipment is essential for product development and performance verification. A Battery Simulator provides a controlled environment for reproducing battery operating conditions, testing charging and discharging processes, and evaluating power electronics.
The JH150V120A-3KW combines power source and electronic load functions in one integrated system. Its bidirectional energy transfer and seamless cross-quadrant switching allow users to switch between energy supply and absorption. This integrated design reduces the need for separate equipment and helps simplify testing system configurations.
Integrated Source-Load Design and Multiple Operating Modes
The JH150V120A-3KW supports different operating modes for various testing requirements. In source mode, it provides constant-voltage output with bidirectional current. Load mode offers constant-current (CC), constant-voltage (CV), constant-resistance (CR), and constant-power (CP) operation. Battery mode supports constant-current discharge, constant-current charging, and constant-voltage constant-current charging.
These functions make the equipment suitable for battery simulation, charge-discharge testing, and power electronics development. Its feedback-based architecture also helps improve energy utilization and reduce overall system implementation costs.
High Precision and Stable Performance
The model provides a DC voltage range of 5V–150V, maximum current of ±120A, and rated power of 3KW. Voltage setting accuracy reaches ±0.02% F.S., while current setting accuracy reaches ±0.05% F.S. With voltage resolution of 1mV and current resolution of 1mA, it supports precise parameter adjustments for different test conditions.
Remote compensation is less than 1% F.S. ±2V. The equipment operates with a single-phase AC input of 187Vac–253Vac and achieves 90% rated efficiency. These specifications make it a practical choice for applications requiring controlled and repeatable electrical testing.
Modular Design and Flexible Expansion
Different laboratories and production environments may require different output capacities. The modular design supports current-sharing parallel operation, allowing multiple units to work together when greater capacity is needed. Output channels can also be freely configured and combined, with customization available for specific applications.
For system integration, the equipment supports TCP, RS485, RS232, CAN, Ethernet, and MB-Slave communication. Users can operate it through the display, buttons, and rotary knob, or connect a host computer for remote control. Its compact 2U design helps simplify installation in test cabinets and laboratory systems.
Manufacturing Quality and Applications
Reliable power equipment requires careful control throughout manufacturing. A typical production process includes component selection, incoming inspection, circuit board assembly, power module integration, wiring, and cooling structure installation. Attention to electrical connections and heat dissipation helps support stable operation.
After assembly, functional checks can evaluate voltage and current output, operating-mode switching, communication performance, and protection functions. Final inspection and operational verification help maintain product consistency before packaging and delivery.
The JH150V120A-3KW is suitable for power electronics development and testing, energy storage system development, battery simulation and charge-discharge testing, and ATE/ATS system integration.
Choosing the Right Battery Simulator
When selecting a Battery Simulator, buyers should consider voltage and current requirements, operating modes, output power, accuracy, communication protocols, and future expansion needs. Matching these specifications to the actual application helps improve testing efficiency and avoid unnecessary system complexity.
With integrated source-load architecture, bidirectional energy transfer, precise control, and modular expansion, the JH150V120A-3KW offers a flexible solution for modern battery and power electronics testing.
