On the occasion of the presentation of its results, Tesla announced that it wanted to equip its Cybertruck and its Semi with an 800-volt architecture. Let’s see what will change.
There will be change on the side of Tesla. While the range has greatly expanded, with the arrival of the Model 3 and Model Y, whose deliveries began in the summer of 2021 in France, the firm is preparing other launches. One thinks in particular of that of the Cybertruck, which should nevertheless not arrive on the roads before next year, as announced by Elon Musk.
But in addition to releasing new models, the Californian firm is also working on the development of new technologies, in order to make them more efficient, more comfortable and more connected. Tesla has indeed filed numerous patents concerning all kinds of innovations, such as laser wipers or heated seats that work in a way never seen before, using fluids and no longer simple resistors.
800 volts for Cybertruck and Semi
During the conference announcing the results of the first quarter, relayed on YouTube, Elon Musk announced the arrival of a completely different technology on his vehicles. Asked about the possibility of turning to 800-volt technology, the Tesla boss replied in the affirmative. If it will not be implemented on the Model 3 and Model Y, due to cost, other models will be affected.
This is particularly the case with Cybertruck, as well as the Tesla Semi, for whom the integration of this technology, which takes the form of a battery whose voltage is 800 volts, instead of 400, would be more consistent. More massive, these vehicles indeed need a much greater flow of energy so that the batteries can be recharged more quickly. Nevertheless, this technology will have a very high cost for the brand, and would only be of interest and profitability on the largest models.
But why go from a 400 volt architecture to 800 volts? Increasingly popular, it has many advantages. Indeed, it makes it possible to increase the power and therefore the charging speed, and will allow manufacturers to integrate batteries of reduced size. As a result, the latter will then be even faster to recharge, in just 10 to 15 minutes depending on the model. And who says smaller size also says lower weight.
So many advantages that have a direct impact on autonomy and production costs. Unsurprisingly, this will affect the price paid by customers. No wonder more and more models are adopting this technology, including the Porsche Taycan, the Kia EV6, the Hyundai Ioniq 5 or the Audi e-tron GT.
