BATTERY
The battery pack is fully designed, validated, and built in Maranello and is integrated into the floorpan, helping to lower the car’s centre of gravity. It consists of 210 cells connected in series and delivers a gross energy capacity of 122 kWh at 800 V. Peak discharge power is 830 kW, and it is possible to recharge 70 kWh in 20 minutes using a fast-charging station capable of delivering up to 350 kW.
The cells, co-designed together with SK on®, are of the pouch type with a capacity of 159 Ah, with a graphite anode and a high-nickel nickel-manganese-cobalt cathode and liquid electrolyte. This technology achieves a density of over 740 Wh/l and a specific energy of 305 Wh/kg; in the application co-developed with Ferrari, the cell is capable of delivering up to 1200 A peak discharge current.
One module is made up of 14 cells; each pair of cells shares an aluminium heat sink to remove heat; between each mini‑module there is an insulating layer that distributes compression and creates a thermal barrier.
The 14 cells in the module are compressed by two lateral aluminium plates; the module has an upper and a lower aluminium sheet that are laser-welded to the side plates, thereby forming the module structure. Two side covers protect the CSC (Cell Supervisor Controller) and the cell connections. They are made of aluminium and SMC and are internally protected by layers of thermal and electrical insulation. Fifteen modules are installed in the pack, 13 in the floor and 2 beneath the rear seats.
Cooling is handled by a network of hydraulic connections and three plates, two of which are fixed to the floor of the housing and one smaller plate located on the second level to cool the upper modules. These plates are specifically designed with multiple internal channels to manage supply and return in a single unit and thus ensure temperature uniformity, which is necessary to prevent cell ageing and to consistently deliver maximum performance. This circuit inside the battery is also optimised to be integrated into the vehicle’s main cooling system.
The e-Box, located behind the second level of modules, houses the power electronics, which include the BMS (battery monitoring system), fuses, relays, and various sensors (current, gas, etc.). The e-Box manages power flows and communication via the CAN bus. In addition, there is a main fuse that interrupts current within three milliseconds in the event of a short circuit exceeding 2000 A.
The battery housing integrates all the subsystems and consists of two aluminium sheets forming the floor, plus castings and aluminium panels that make up the side ring. These components are assembled without welding, using mechanical fasteners and adhesive material, which together with the cover provides both structural and sealing functions. There are 20 central anchoring points that secure the modules to the housing and, once anchored to the chassis, the lower shell actively contributes to increasing the rigidity of the body.
The battery follows Ferrari’s philosophy of total integration: the six rows of modules fixed to the floor contribute to stiffness via the module compression plates. This approach has made it possible to achieve an energy density close to 280 Wh/l and a power density of around 1.9 kW/l, at the top of the segment, making it one of the most competitive battery/chassis systems in the world.
