Product catalog summary

Introduction
The D1000 Series Battery Pack Charge-Discharge Test Power Supply is a bidirectional DC source designed for testing battery packs. It integrates software simulation algorithms, measurement, and control technologies, offering high voltage and current control accuracy, low ripple output, and fast current response. It is widely used by battery companies, OEMs, and laboratories for evaluating battery performance, including capacity, DC internal resistance, cycle life, and temperature.

Product Advantages
The D1000 Series supports customized test conditions through editable work steps and work condition simulation. It allows data import for testing and supports DBC file import for communication with various Battery Management Systems (BMS). The product offers wide voltage and current output, high accuracy and resolution, and a high dynamic response time of 2ms. It features a multi-filter solution with a current ripple of ≤0.2% FS and an optional ripple overlaying function. Energy recovery to the grid is supported across the full power range with a power factor of ≤0.99. Standard communication interfaces include RS485, CAN, and LAN.

Specifications
The D1000 Series models vary in power, current, and voltage specifications, with options ranging from 60kW to 600kW, current capacities from 200A to 800A, and voltage ranges from 5V to 1600V. The input characteristics include voltage and current accuracy of ±0.1% FS, current rise/fall time of ≤5ms, and charge-discharge switching time of ≤10ms. The main channel data acquisition speed is 10ms, with a current ripple of ≤0.2% FS. The resolution for voltage, current, and power is 0.001V, 0.001A, and 0.001kW, respectively. Protection features include OVP, OCP, OTP, phase loss, and emergency stop.

Input and Feedback Characteristics
The input requirements specify a three-phase, three-wire plus PE connection with a voltage of 400V ±10% and a frequency of 50Hz ±5Hz. Energy recovery is available across the full power range, with iTHD ≤3% and a power factor of ≥0.99.

Communication Interfaces and Control Program
The local interface includes an LCD, while remote communication is possible via RS485, LAN, and CAN. Additional features include external emergency stop, fault signal, and voltage compensation. The system supports up to 9999 work steps and cycle indices, with loop testing capabilities of up to 10 layers.

Safety and Ambient Conditions
The insulation resistance is ≥20MΩ at 500Vdc, and the voltage withstand is 3000Vdc for 60 seconds without arcing or breakdown. The cooling method is air cooling, with an ambient temperature range of -10 to 40°C, relative humidity of 0-90% RH (non-condensing at 25°C), and an altitude limit of ≤2000m.
