Ferrari turned to a solution known from mobile phones. It modified the battery cells for higher performance.

Ferrari’s electric vehicle Luce uses pouch cells from SK On, with terminals modified for higher currents. The battery design also allows for future module replacement.

Same type of casing as batteries in phones

Ferrari’s first electric car employs a battery cell design also found in smartphones. The Luce model features so-called pouch cells, which the automaker developed together with South Korean company SK On. This format is already used in other electric vehicles as well.

Instead of a solid metal casing, these cells have a cover made of laminated aluminum-plastic film. This reduces weight and enables the cell dimensions to be adjusted during design to fit the required space. The finished cells are then assembled into battery modules.

For Ferrari, the ability to deliver high current was crucial. According to project lead Andrea Binotti, as quoted by Autoblog, SK On therefore modified the current outlets of the cells to handle higher current loads.

Acceleration also depends on how quickly the battery delivers energy

Capacity determines how much energy the battery can store. The Luce has four electric motors that, according to Ferrari, provide over 1,000 horsepower together in Boost mode.

The battery has a gross capacity of 122 kWh and uses an 800V architecture. A total of 210 cells are divided into 15 modules. According to the design description, each pair of cells shares an aluminum cooling plate that dissipates the heat generated during operation.

Ferrari states that the specific energy of the cells is 305 Wh/kg, while the entire battery pack has a specific energy of 195 Wh/kg. The weight of cooling systems, protective enclosures, and other components reduces the specific energy of the whole pack. Therefore, it is important not to confuse these two values when comparing with other electric vehicles.

The design allows for future cell replacement

Ferrari assembles its battery packs in Maranello, and their enclosure is part of the vehicle’s structural framework. There is still space inside for maintenance and future technology upgrades. The company plans to be able to replace cells and modules with newer versions.

Elena Ligabue, the head of battery pack development, explained to CarExpert that the chassis and enclosure will remain intact, while the cells and modules can be replaced with newer ones in the future. This way, owners won’t have to rely solely on the original type of cells going forward.
