Design of an embedded hardware platform for cell-level diagnostics in commercial battery modules
arXiv:2603.29107v1 Announce Type: cross Abstract: While battery aging is commonly studied at the cell-level, evaluating aging and performance within battery modules remains a critical challenge. Testing cells within fully assembled modules requires hardware solutions to access cell-level information without compromising module integrity. In this paper, we design and develop a hardware testing platform to monitor and control the internal cells of battery modules contained in the Audi e-tron battery pack. The testing is performed across all 36 modules of the pack. The platform integrates voltage sensors, balancing circuitry, and a micro-controller to enable safe, simultaneous cell screening without disassembling the modules.

Abstract:While battery aging is commonly studied at the cell-level, evaluating aging and performance within battery modules remains a critical challenge. Testing cells within fully assembled modules requires hardware solutions to access cell-level information without compromising module integrity. In this paper, we design and develop a hardware testing platform to monitor and control the internal cells of battery modules contained in the Audi e-tron battery pack. The testing is performed across all 36 modules of the pack. The platform integrates voltage sensors, balancing circuitry, and a micro-controller to enable safe, simultaneous cell screening without disassembling the modules. Using the proposed testing platform, cell voltage imbalances within each module are constrained to a defined reference value, and cell signals can be safely accessed, enabling accurate and non-invasive cell-level state-of-health assessments. On a broader scale, our solution allows for the quantification of internal heterogeneity within modules, providing valuable insights for both first- and second-life applications and supporting efficient battery pack maintenance and repurposing.

[R] ICML Anonymized git repos for rebuttal
A number of the papers I'm reviewing for have submitted additional figures and code through anonymized git repos (e.g. https://anonymous.4open.science/ ) to help supplement their rebuttal. Is this against any policy? I'm considering submitting additional graphs during the discussion phase for clarity, and would like to make sure that won't cause any issues submitted by /u/drahcirenoob [link] [comments]

Show HN: Vim Navigator – MCP server that lets AI agents drive your Neovim
I use Coding tools daily and got tired of it describing code by line numbers. So I built an MCP server that lets the agent control my Neovim instance instead: opening files, highlighting lines, adding annotations, splitting views. The tool I actually wanted was "walkthrough mode": I ask the agent to walk me through a PR, it opens each file, highlights what matters, explains briefly, and waits for my questions. Turns code review into pair programming where the agent points at the screen. It also works passively — while the agent investigates a bug or reads code, my Neovim follows along so I can see what it's looking at. Built with pynvim, talks to Neovim via --listen socket. Works with any MCP client. https://github.com/kcaldas/vim-navigator Comments URL: https://news.ycombinator.com/item?i
