Qoitech Otii Battery Toolbox

The Otii Battery Toolbox is a software license that enhance the software capabilities of the Otii Product Suite to enable battery profiling, battery simulation, battery testing and validation for low-power embedded and IoT devices. It can be purchased as monthly/yearly subscription or perpetual license.

The Otii software + Automation Toolboxes run on Windows, Ubuntu, and macOS.

Specifications

Battery validation: Charge, discharge in single or multiple steps, cycle discharges, and design custom scenarios. Test and validate one or multiple batteries in real time.

Battery profiling: Create discharge profiles of the batteries with specific conditions for the discharge that reflect how your application is behaving. Use these to emulate batteries.

Battery emulation: Use any Otii box to act as a battery, following a discharge curve of your specific discharge profile. Simulate battery, get the real capacity value for your application.

Battery Toolbox can be use for:

Powerful and cost efficient scalability: Easily scale and reconfigure battery measurement units to match batch validation, benchmarking, or qualification needs, offering flexibility for any task.

Build your own realistic discharge-charge profiles: Validate battery performance with flexibility by creating profiles of device behavior. Combine discharge, sleep, and charge states, and customize discharge steps easily.

Cycle the batteries: Test battery durability by cycling through full charges and discharges to assess aging and stability. No limit on the number of cycles for accurate evaluation.

Simple set-up for battery profiling: Otii Arc Pro sinks 2.5A, sources 5A, and monitors 50nA-5A with 0.1% accuracy. Otii Ace Pro sinks/sources 5A, monitors 25nA-5A with 0.05% accuracy. Connect multiple units via USB hub to discharge batteries simultaneously.

Model sleep & active modes: Create battery discharge profiles to match your application behavior, with low discharge for sleep mode and high discharge for active mode conditions.

Three options for battery discharge: Discharge with constant current, keeping current steady as voltage drops. Discharge with constant power, adjusting current as voltage drops. Discharge by simulating a resistance connected to the battery.

Use Otii hardware as battery: Otii hardware simulates a real battery by following your custom discharge profile. It adjusts output voltage based on load, mimicking internal resistance and voltage drop.

Fixed and follow discharge options: Use “Fixedˮ emulation to simulate the battery at a constant “Used capacity,ˮ staying at a specific point on the discharge curve. Instead, the “Followˮ option simulates real-time discharge, adjusting the batteryʼs behavior as energy is consumed, with the position on the curve moving as your device draws power.

Parallel and series battery set-ups: Emulate setups with battery cells in parallel (up to 4 cells) or in series, depending on the Open Circuit Voltage (OCV). Max OCV: 5V for Otii Arc Pro and 25V for Otii Ace Pro.
