HomeBattery Cyclers & DC Testing Battery Cyclers & DC Testing
For more than five decades, Unico has been providing innovative DC power solutions for industry. We pioneered the first high-power electronic DC servo drives back in 1967. From the earliest stages of automotive HEV development, Unico has supplied DC power solutions for battery simulation. With the 2460 / 2461, we introduce a system engineered specifically for battery cycling and DC testing.
The Unico 2460 / 2461 battery cycling and DC testing system combines the 2460 family of dual-output DC power supplies and 2461 single-output DC Power Supplies with software specifically tailored for testing HEV battery packs, ultra- and supercapacitor packs, fuel cells, power electronic converters, and other devices.
The 2460 / 2461 system is highly configurable and provides the flexibility and performance to accommodate even the most demanding testing applications.
The 2460 /2461 can precisely regulate key electrical parameters such as current, power, voltage, and simulated load resistance
Seamless Mode Switching
On-the-fly toggling between control modes facilitates handling changing parameter constraints.
High-Frequency Update Rates
Typical update rates from 1 kHz (1.0 ms) to 10 kHz (0.1 ms) allow digital control loops to accurately track constant, ramping, or otherwise varying commanded target levels.
Users are provided several options for programming test cycles and load profiles that suit their unique application requirements.
The optional UEdit® tool suite provides embedded programming, data logging, and chart recording capabilities. Ladder and function-block editors define such test features as:
Control mode selection (current, power, voltage, or resistance)
Delay and dwell times
Cycle repeat counts
A fully featured PC controller option is available with the user programming capabilities of widely recognized software packages such as Simulink and LabView.
Rather than program their own test profiles, users can instead select from and execute existing test programs previously developed by Unico. Data logging and test report generation can also be provided. Available test programs, which are part of the LabView test suite, include:
Constant current discharge cycling
Constant and peak power testing
Federal Urban Driving Schedule (FUDS) and similar test regimes
Dynamic stress test (DST)
Partial discharge testing
Hill climb testing
Thermal performance testing
Fast charge testing
Life cycle testing
A high-speed communications interface is optionally available to accept commands from existing customer controllers that are used to generate test profiles. Wired and fiber-optic options are available. Supported protocols include:
The 2460 system incorporates features that protect test articles from overstressing, including:
Reverse voltage clamp
Programmable current, voltage, and power overstress protection
Voltage equalization circuit to limit inrush currents on power-up
Output filters protect from potentially harmful ripple voltage and current
Optional user-defined alarm thresholds including temperature and cell voltage monitoring
Common bus energy sharing
Arc flash compliant data port
