Tesla already uses BYD Blade batteries for the electric cars it manufactures in Berlin

Various Chinese media outlets claim that BYD’s Blade batteries have already begun to hit the market. Berlin gigafactorywhere the American manufacturer will begin to mount them on its electric cars this same month of august. Therefore, the Model Y will be the first to incorporate these new batteries from the Chinese manufacturer that, for now, will not be used in the factory. Shanghai.

The Gigafactory in Berlin will be the first to use Blade batteries, as rumors from a year ago anticipated that a prior supply contract had already been signed between the two companies. The information about the arrival of the batteries in Germany comes from the local media Sina-Tech. The same source indicates that the first electric cars with these batteries are expected to come off the production lines. between late August and early September.

The news confirms what was said at the beginning of June by Lian Yubo, BYD Executive Vice President and Director of the Automotive Engineering Research Institute in an interview with state media outlet CGTN, announcing that BYD would soon supply batteries to Tesla (although it should be noted that the video of that interview posted on Weibo was later removed , and local media quoted people close to Tesla as saying they had not heard of him). On June 14, Auto Time quoted a source close to BYD’s battery manufacturing unit, FinDreams Battery, as saying supplying Tesla with batteries was a sure thing.

Currently, the only electric car rolling off the manufacturing lines at Tesla’s Gigafactory in Berlin is the Model Y, according to Auto Time, citing sources familiar with the matter. He further added that the progress in this cooperation was not advancing quickly and that the massive use of BYD batteries by Tesla may not happen until next year.

BYD Blade Battery
BYD’s Blade batteries are structurally very similar to the ones Tesla is making with 4680 cells.

For Tesla electric cars made in China, current battery suppliers are CATL and LG Energy Solution, which provided 70% and 30% of the supply in 2021 respectively. For now, BYD is not expected to join these suppliers. The batteries have not arrived at the facility and there is no information that they will soon, according to the latest information from Sina Tech.

In March 2020, BYD introduced a new battery for electric cars called ‘Blade Battery’ that uses LFP (Lithium Iron Phosphate) chemistry and qualifies as indestructible, since they can, it can withstand all kinds of damage on it, without reacting with explosions or fires. These batteries have been subjected to nail penetration, heating in a 300°C oven, 260% electrical overload and crushing by being driven over by a 46-tonne truck establishing a new level of safety.

Battery dispenses with the usual modules in which the cells meet and then, once connected to each other, create a complete battery. In this way it saves a great amount of space in connectors and control systems, increasing the space available for the active material in a fifty %always according to what BYD indicates.
