Tesla Announces Switch to 48V System

Tesla Inc. (NASDAQ: TSLA) continues to make advancements toward its own electric cars’ low-voltage systems, which up until this point have been running at about 12 volts, exactly like the great majority of conventional cars. Representatives of Tesla recently announced the company’s aim to launch a 48-volt system. Although the system has been around a long time, this remains a unique solution in the automobile industry.

Tesla’s initial stage was the transition from 12-volt lead-acid batteries to all-new li-ion 12-volt auxiliary batteries, a move that was announced in February 2021. These batteries were first introduced in the updated Tesla Model S and Model X, beginning with the Plaid, and then utilized in the Model 3 and Model Y later in 2021.

Tesla states that the older lead-acid batteries were allegedly the primary cause of problems within Tesla cars and that there was a need for them to be replaced within a four-year period of time or so. The brand-new li-ion batteries are anticipated to last the lifespan of the vehicle, necessitating absolutely no replacement, which is a noticeable improvement. In addition, the smaller dimensions and lighter weight — a reduction of 87% — were also introduced.

According to Tesla, this 48-volt low-voltage technology will be employed. The Tesla Cybertruck (due out this year) is going to be the brand’s first electric vehicle to be equipped with the new 48-volt system, followed by the humanoid Optimus robot and all other upcoming electric cars from Tesla.

Just for the sake of reference, the auto sector switched from 6 volts to 12 volts during the 1960s. As of now, the 6 volts are typically used in small cars while 24 volts systems are used in large cars.

The 48-volt system will be employed by Tesla because, in contrast to the 12-volt system, it will cut the current by four times. The level of this voltage is generally regarded as secure. The need for higher voltage is because 12-volt lines are getting thicker, heavier and more expensive, while the power requirement for electrical gadgets onboard is continually rising.

There are going to be significant weight and cost reductions when the 48-volt system is employed, and efficiency may even go up. That is a truly intriguing shift that will also call for a new 48-volt li-ion auxiliary battery; in Tesla’s case, this battery may even be manufactured locally, though this is uncertain at the moment.
