An electric vehicle’s battery’s size directly impacts its production cost, how fast it charges, its range, its performance, and how rapidly it accelerates, among other factors. As Porsche considers making the switch to electric vehicles, its engineers and designers must consider one question: what should be the battery size be to meet Porsche buyers’ expectations?

Porsche claims in a blog post that the size of an electric car battery is primarily accountable for the vehicle’s carbon footprint. It is, nevertheless, the factor that determines whether or not an electric car succeeds on the market.


To ensure that the vehicles satisfy the expectations and demands of the customers, the size of the battery must be appropriate. According to the corporation, they are working hard to figure out how big the battery in its electric vehicles ought to be so as to meet all of its customers’ demands. 

For instance, they want a dynamic driving experience while yet expecting their cars to traverse great distances rapidly and charge swiftly. Many individuals believe that for dynamic performance, a bigger battery is required, although simulated lap times at the Nürburgring imply otherwise. A virtual Taycan Turbo S with an 85.1 kWh battery and a weight of 2419 kilos can finish a lap in 7:39.5 minutes, according to Porsche.

The overall car weight drops to 2310 kg whenever the battery capacity is dropped to 70 kWh. However, the Taycan takes seven-tenths of a second longer to finish the lap due to decreased battery power. The lower vehicle weight allows it to speed from zero to 100 km/h in 2.90 seconds, which is 0.02 seconds quicker compared to the reference automobile.

However, the Taycan spends 9.51 seconds to get to 200 km/h in this configuration. This is about eight-tenths of a second slower. According to these estimates, the actual weight savings does not offer compensation for the battery’s reduced power.

A 100 kWh battery provides an additional 107 kg to the car’s overall weight. Notwithstanding the more robust battery, the lap time rises to 7:42.4 minutes, with acceleration times of 3.04 seconds for zero to 100 km/h and 9.71 seconds for zero to 200 km/h.

With a 130-kWh battery, the weight of the car rises to 2743 kg, and the impact of weight becomes even more apparent. The lap time climbs to 7:48.2 minutes with this combination, while acceleration from zero to 100 km/h takes 3.28 seconds. Getting to 200 km/h from zero takes 10.48 seconds.

800-volt technology & DC charging

Although a smaller battery is preferable for decreasing CO2 emissions during manufacture, Porsche’s research shows that a medium-sized battery provides the optimum driving performance. Larger batteries are thought to have a longer range and shorter journey times. 


Nonetheless, because of its 800-volt technology and very effective direct-current charging method, the Taycan can retain sufficient energy to travel an additional 100 kilometres in just 5 minutes. Many studies have suggested a two-hour driving time followed by a 15-minute charging time, and the Taycan is indeed capable of travelling considerable distances whenever driven in this manner.

Reducing Carbon Emissions

Porsche is dedicated to drastically decreasing the carbon footprint of its vehicles and production process, in accordance with the Volkswagen Group’s principles. Its second-generation electric cars, which have yet to be released, will emit around 25% less CO2 throughout the course of their lives than the first-generation versions. 

According to the business, new cell technologies will minimize energy consumption whilst increasing charging capacity would boost efficiency. Furthermore, an increase in the percentage of raw materials accessible from used batteries promises a significant improvement in sustainability, giving Porsche a genuine chance to meet its 2030 goal of becoming carbon neutral across the whole value chain.
