# Cell Level Battery Converters Mercedes-Benz Adds Individual Cell Control With Its Power Converter By Adam Harrie | Written with AI assistance | Published 2026-11-12 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/cell-level-battery-converters References: [driving](https://driving.ca/auto-news/technology-news/mercedes-benz-power-converter-better-range-efficiency)  Mercedes-Benz’s ‘Power Converter’ brings cell-by-cell control to EV batteries, using software and microconverters to charge or discharge each cell independently instead of handling the pack as a single unit. That gives [electric drive systems and charging hardware](https://www.trendhunter.com/trends/fastcharging-ev-stations) bidirectional voltage conversion across different battery layouts. The system can maintain output at up to 800 volts even when cells have different charge levels or ages. It also separates high-voltage delivery from a fixed series cell count, so power moves only where it is needed. This supports [smaller EV architectures](https://www.trendhunter.com/trends/upgradeable-city-car-batteries) and adds modularity during assembly. Treating cells individually can also [extend battery pack life](https://www.trendhunter.com/trends/Texas-Instruments). Cell-by-cell charging turns the battery pack into a more modular EV component, making smaller architectures more plausible without sacrificing output. An 800-volt target that no longer depends on a fixed series layout shifts battery design toward durability and assembly flexibility, not just raw cell count.
