Exploring Porsche’s Lightweight Battery Technology

This principle applies to every component, including the Porsche lightweight battery. You can find out more about how this reduces weight without sacrificing power by visiting your local Porsche center.

Gas-Powered Models

Much of the conversation around batteries focuses on electric and hybrid vehicles, but Porsche also leads the field in offering two different types of lighter batteries for its gas-powered cars.

Lithium-Ion Batteries

Lithium-ion batteries are the lightest type available, and can be fitted to many of the performance models, such as the Panamera and 911. These batteries can be up to 22 lbs lighter than conventional lead-acid batteries, which helps maintain a superior front-to-rear balance. This is mounted in the same place as a regular lead-acid battery and can be fitted to the same tray, despite the difference in size.

At first glance, the lithium-ion battery may seem to be less powerful, typically 12 volts offering a capacity around 20–40 Ah. This may be lower than a standard lead-acid battery, but lithium-ion batteries are more efficient. They can draw on almost 100% of their capacity compared to just 30% in standard lead-acid batteries, providing more power from a smaller unit.

Absorbed Glass Mat (AGM) Lead-Acid Batteries

Although lithium-ion batteries are the lightweight option for Porsche cars, some models can also be fitted with an absorbed glass mat lead-acid battery. These are not specifically lightweight batteries but are lighter than the conventional flooded lead-acid battery while still delivering exceptional performance.

Electric Batteries

Porsche has adopted an innovative approach to its fully electric models, creating a lightweight lithium-ion battery design that maximizes power while minimizing weight. Several strategies combine to reduce the weight while still delivering outstanding power and rapid acceleration. These include lightweight aluminum housing, high-voltage architecture requiring fewer cables, and battery cells wrapped in foil, protected by aluminum.

The overall structural design also contributes to the lower weight in electric Porsches. Rather than having separate battery housing, the load-bearing frame incorporates an area for the battery, eliminating the need for separate heavyweight casing. This, combined with the placement of the battery low in the chassis, creates the lightest possible weight.

Hybrid Batteries

There are also hybrid vehicles in Porsche’s range, and these also have a lithium-ion battery that works with their traditional combustion engines. These battery packs power the electric motor but are smaller than the full-EV battery packs, typically offering 370 volts and 25-26 kWh. The hybrid models also carry a conventional 12-volt battery that powers the combustion engine and works in tandem with the lightweight lithium-ion battery pack.

Porsche consistently leads the way with precision engineering and cutting-edge technology that ensures every car delivers an unparalleled performance. To find out more or schedule a test drive, contact us today at Porsche North Scottsdale in Phoenix, AZ.
