Porsche EV, the Taycan, can already be found driving across the highways here in the United States. When comparing luxury EV sedans, it comes down to the Tesla Model S, the Audi E-Tron, and the Porsche Taycan. All are unique in their own way and each have a differentiating factor. Today we are going to look at one of the Taycan’s differentiating factors. That being the makeup of its battery. 

According to Porsche, the Taycan is the first production vehicle with a system voltage of 800 volts instead of the usual 400 volts for electric cars. This high voltage enables consistent high performance, reduces the charging time, and decreases the weight and installation space of the cabling. The two-tier Performance Battery Plus used in the Taycan S and Taycan Turbo contains 33 cell modules consisting of 12 individual cells each. The total capacity is 93.4 kWh. The cells are called pouch cells. Within pouch cells, the stack of electrodes is not enclosed by a rigid housing, but by a flexible composite foil. This allows optimal use to be made of the rectangular space available for the battery and a reduction in weight. 

Porsche has found success in this battery makeup because they have systematically built up their expertise in the field of chemistry for high-performance batteries. Porsche has found that in order to meet the extreme demands placed on cell systems in high-performance applications, it is necessary to change the cell chemistry from graphite to silicone anodes. New electrolytes and additives allow operation even at temperatures above 75 degrees Celsius. 

Silicon is relatively new in the EV battery world but Porsche believes that it has a big potential. Porsche’s EV, the Taycan, has a battery that has a makeup like no other and is projected to improve even more as Porsche engineers continue to test and research with silicon instead of graphite.

The EV battery industry is changing drastically and new findings are right around the corner. Stay updated on all of the news regarding EV batteries here on our monthly blog.
