Hioki SS7081-50 Battery Cell Voltage Generator

Description

The Hioki SS7081-50 Battery Cell Voltage Generator is a 12-channel instrument that integrates the functions of a power supply, electronic load, and digital multimeter (DMM) into a single package. It is designed for the high-precision testing and evaluation of battery management systems (BMS) for lithium-ion battery packs found in electric vehicles (EVs) and energy storage systems (ESS).

Key Features

• Simulates battery cells: The SS7081-50 can replace actual batteries, allowing engineers to create a controlled and repeatable test environment for BMS development and quality assurance.
• Scalable system: Up to ten units can be connected in a series to simulate a battery pack with a series voltage of up to 1,000 V (5 V/channel x 200 channels).
• Safe simulation: It can safely simulate hazardous conditions, such as cell anomalies, short circuits, and broken wires between the BMS and battery cells, without the risk of fire posed by using real batteries.
• 12 independent channels: Each of the 12 channels can be independently set and controlled for voltage and current.
• High-accuracy output: It provides high-accuracy voltage output to simulate cell behavior precisely.
• Two-quadrant output: The instrument supports cell balancing, which involves discharging (-1 A) and charging (+1 A), with two-quadrant output voltages.
• High-precision measurement: It offers high-precision voltage and current measurement capabilities, including a 100 µA range for accurately measuring minuscule currents like dark current and standby current.
