800-volt electrical architecture: Tesla could take the plunge

During the recent conference organized as part of the publication of the 1st quarter results, the entire board of directors of the company and in particular the CEO, Elon Musk, were interviewed by many guests. Management was asked about the possibility of making the jump to an 800-volt electrical architecture.

A significant cost

If the market already has several models in which this type of architecture is implemented, such as the Porsche Taycan, the Audi e-tron GT, the KIA EV6 or the IONIQ 5, Tesla is currently continuing to equip its models of a maximum of 400 volts.

A choice linked above all to financial reasons and cost savings, as underlined by the various managers present.

In the range of current models, especially in the Tesla Model 3 and the Tesla Model Y, the manufacturer has ruled out the integration of this type of architecture because it would entail an enormous financial burden that would occur little in the final improvement of the product. .

According to Andrew Baglino, senior vice president of energy and powertrain engineering at Tesla, the benefits they and the customer could derive would be minimal while the selling price and cost of production would increase. medium.

Tesla does not abandon the idea of ​​equipping Semi and Cybertruck with 800 volt system

Nevertheless Andrew Baglino concedes that the implementation of an 800-volt system would mean a reduction in the charging time of his models, and that it is a highly anticipated technology in the electric vehicle sector.

As a result, Tesla is not abandoning the idea of ​​installing 800 volts in models like the Tesla Cybertruck or the Tesla Semi, vehicles that are “massive” to say the least, which will require a much greater flow of energy to recharge. their batteries quickly.

Elon Musk himself responded jointly with Andrew Baglino on the subject. Going from 400 to 800 volts would entail huge costs for the company, mainly in updating the charging infrastructure of the vehicles, as well as incorporating the whole system into the vehicle itself to make it work with high voltage levels.

Tesla would only be prepared to bear these costs for vehicles where it is really necessary, in the meantime the most accessible models in the range will continue to have the 400-volt architecture.

800 volts: the architecture of tomorrow

With a few exceptions in the automotive market, almost all consumer electric vehicles currently have a charging architecture around 400 volts. Only a small handful of brands offer 800-volt cars, such as Porsche, Hyundai, KIA and Audi.

Lucid is the only one to offer up to 900 volts thanks to its own proprietary technology.

However, the trend should be imposed in the years to come, the market could even be dominated by an 800 volt architecture in a general way, according to a recent article from Automotive News.

to summarize

Tesla was planning to launch an 800-volt architecture on its two largest electric vehicles that should arrive in the coming months: the Tesla Semi and Tesla Cybertruck.
