Twaice Raises €24M to Revolutionize Battery Analytics

Twaice, a Munich-based startup specializing in predictive battery analytics, has just secured €24 million from the European Investment Bank (EIB). Founded in 2018, the company already counts Audi and Mercedes-Benz among its clients. With this long-term loan backed by the InvestEU program, it's now setting its sights on the stationary energy storage systems (BESS) market.

"As storage operators expand their fleets, they need operations that scale with them." — Dr. Stephan Rohr, Co-CEO of Twaice

What Twaice Actually Does

The initial promise is simple to sum up: knowing, before it breaks, what condition a battery is in. Twaice built its reputation on predictive analytics software capable of measuring an accumulator's degradation—that is, the progressive loss of storage capacity—and anticipating its remaining lifespan. To achieve this, the system cross-references real-time data with usage history. Nothing magical: it's applied statistics to cell chemistries.

This type of tool interests automakers for a very concrete reason. A 60 to 100 kWh battery costs between €8,000 and €15,000 to replace. If you can predict a failure six months in advance, adapt charging strategies, or modify the battery management software (BMS), the savings are substantial. Audi and Mercedes-Benz figured this out, hence their collaboration with Twaice from the early years.

Why the EIB Is Shelling Out €24 Million

The European Investment Bank doesn't hand out money randomly. This €24 million loan, secured via the InvestEU program, aligns with a clear direction: Europe wants to structure a local energy storage industry, less dependent on Asian cell suppliers.

Twaice doesn't manufacture batteries. It's a software analytics publisher. This positioning is precisely what makes the investment strategic: the data and algorithms developed in Europe can support any type of chemistry—LFP, NMC, sodium-ion—without being tied to a particular cell supplier.

From Electric Vehicles to Stationary Storage: The Strategic Pivot

This is where the story gets interesting. Twaice isn't just trying to grow in automotive. The company is pivoting toward BESS—those large storage systems installed behind photovoltaic panels, upstream of fast-charging stations, or at industrial sites to shave peak consumption.

The mechanics are the same as for car batteries, but the financial stakes are different. An industrial BESS system can represent several million euros in investment. Knowing whether it will last 10 or 15 years, predicting when its capacity will drop below 80%—the usual end-of-life threshold—directly impacts a project's profitability.

"The EIB's long-term financing helps us further accelerate the growth we're already seeing," says Stephan Rohr. Translation: the order book is already there. This funding is about keeping pace, not finding a first customer.

Specifically, What Use Cases for BESS?

The stationary storage systems Twaice is targeting cover several markets. First, storage coupled with photovoltaics: energy produced at noon is saved for evening consumption. Second, buffering for fast-charging stations: a 150 to 350 kW charger draws a massive current from the grid. With an intelligently managed buffer battery pack, you avoid peak draw and penalties for exceeding subscribed power. Finally, industrial peak shaving, which follows the same logic.

In all these cases, the battery's lifespan and reliability are directly tied to project profitability. Predictive analytics that detect a cell drifting before it derails an entire module—that's uptime gained and maintenance costs reduced.

Why This Raise Goes Beyond Twaice

This funding says something about the state of the market. Automakers have started integrating battery analytics tools, but the BESS segment is still largely under-equipped with sophisticated monitoring software. Most storage fleet operators are still managing their batteries with basic tools, far from what predictive models can achieve.

The EIB's involvement in this type of deal also signals that Europe considers mastery of battery data a strategic priority.
