Description
This reference design provides a modular battery test solution allowing users to have the flexibility to test batteries at different current levels with one design. This design leverages the TIDA-01041 reference design by providing two 100-A battery testers that can work independently or be connected in parallel to increase the maximum current output from 100 A to 200 A. This design describes the design theory, part selection, and optimization of this solution.
Features
- Modular design capable of 200 A maximum charge and discharge
- High-precision calibration control achieving 0.02% full-scale current control accuracy and 0.02% voltage control accuracy
- Input voltage (bus) from 8 V - 16 V and output load (battery) from 0 V - 4.2 V (5 V max)
- Up to four LM5170-Q1 multiphase bidirectional buck, boost integrated controllers and drivers for charging and discharging
