A battery is having a bad day. Qnovo notices first.
Somewhere in a Hyundai EV outside Seoul, cell number 4,217 in a pack of several thousand begins to misbehave. Its internal resistance ticks up by a sliver of a millivolt. Nothing a human would feel. Nothing a dashboard would flag. But a stream of telemetry is climbing into the cloud, and a model trained on the behavior of millions of other cells is already making a decision: ease the charge, log the anomaly, alert the OEM. The driver finishes their commute. The recall that almost happened doesn't.
This is the quiet work of Qnovo - a software company that has spent fifteen years arguing that the bottleneck in modern batteries isn't chemistry. It's the firmware. The pitch is unfussy: take the same lithium-ion cells everyone else uses, wrap them in smarter math, and you get longer life, faster charging, and a meaningfully lower probability of thermal runaway.
The argument has aged well. First-generation Qnovo code shipped inside more than 150 million smartphones. In March 2026, Hyundai Motor and Kia made it official by writing a check and calling Qnovo a strategic partner. The cars came late, but they arrived.
Small company, large surface area.
The algorithm that doesn't trust the spec sheet.
Most fast chargers follow a fixed curve. SpectralX reads the cell in real time and rewrites the curve as it goes - pushing speed where the chemistry can take it, easing off where it can't. Result: OEMs feel comfortable extending warranties on packs that used to scare their lawyers.
A fire alarm for the cells you can't see.
SentinelX watches every cell in an EV pack and assigns a risk score in real time. Qnovo claims 98.7%+ accuracy in flagging the cells most likely to fail. For automakers, that is recall insurance with a software license fee attached.
Four bets on one belief: software eats the battery.
SpectralX AFC
Adaptive fast charging that dynamically retunes the charge profile based on the live state of each cell.
SpectralX HSD
Health and safety analytics surfacing unstable cells before they become incidents - or warranty claims.
SentinelX
The automotive-grade safety layer aimed at a zero-recall future for EV batteries.
Battery Genome Database
A cloud dataset of battery behavior across chemistries - the training corpus that makes the rest of the stack smarter.

Three founders, one long bet.
Nadim Maluf
The face of Qnovo for over a decade. Engineer-turned-CEO who has spent his career arguing that battery progress runs through software, not chemistry.
Dania Ghantous
Head of Technology and a 2026 Woman Automotive Leader of the Year finalist. Architect of much of the underlying battery intelligence.
Fred Berkowitz
The third name on the original cap table. Helped shape Qnovo's earliest work on adaptive charging.
Phones, then cars.
The boring layer is finally interesting.
Battery Management Systems used to be the part of the car nobody wrote a press release about. A circuit board. Some thermistors. A firmware blob. The marketing was reserved for the cell - new chemistry, new gigafactory, new range number.
Qnovo's bet is that the BMS layer is where the next decade of competitive advantage actually lives. Two cars built on identical cells can behave radically differently if one of them is running smarter software: faster charging without degradation, fewer thermal events, longer warranties, higher residual value.
That bet maps neatly onto the broader automotive shift toward software-defined vehicles, where features are unlocked, tuned, and updated over the air. A battery whose behavior is a software variable is exactly the kind of subsystem automakers now want.
It also maps onto the harder economic argument: an EV battery recall can wipe out a year of operating margin. SentinelX is, fundamentally, a product priced against that risk.
Things worth knowing.
Links, demos, deeper reading.
Back to cell number 4,217.
The driver pulls into the garage. Plugs in. Walks inside to make dinner. Somewhere in the cloud, SentinelX has already flagged cell 4,217 for closer monitoring. The fast-charge curve for tonight's session has been quietly downgraded by twelve percent. The pack will be ready by morning. The owner notices nothing.
That, in the end, is what Qnovo sells: a thing you never have to think about. No press release, no recall notice, no headline. A battery doing exactly what it was supposed to do, for a few more years than it otherwise would have, because thirty-three people in Milpitas decided the most interesting layer of an EV was the one written in code.
