# Tesla's Cybertruck: Setting a New Standard in EV Charging
Written on
Chapter 1: The Charging Challenge
When it comes to electric vehicles (EVs), one of the primary drawbacks is the time required for charging. Even the quickest charging models, like the Tesla Model Y, take around 45 minutes to fully recharge at a rate of 275 kW. This capability, combined with Tesla's extensive supercharger network, once placed them ahead of their competitors. However, as rivals have improved and third-party charging stations have become more common and efficient, Tesla's technological edge has diminished. Recently, though, Elon Musk showcased a game-changing feature of the Cybertruck: it will support charging speeds of 1 MW, similar to the Tesla Semi. This advancement allows the Cybertruck to go from 0% to 70% charge in a mere six minutes. What’s behind this impressive feat?
Section 1.1: The Tesla Semi Advantage
During the Semi Delivery Event, where the first Tesla Semis were handed over to Pepsi, Musk highlighted the Semi's remarkable capabilities. With a 1000 kWh (or 1 MWh) battery, it can travel up to 500 miles on a single charge while carrying a full load. Tesla even shared a time-lapse video demonstrating this impressive range, proving its efficiency is not just theoretical.
The Semi stands out because it employs a unique 1,000 volts (1 kV) architecture, enabling rapid charging at speeds of 1,000 kW (1 MW). At this extraordinary rate, it can recharge from 0% to 70% in just 30 minutes—a timeframe comparable to charging a Model Y from 10% to 80%, despite the Model Y's battery being over twelve times smaller.
What’s striking is that this achievement does not rely on new battery technology. The Semi utilizes the same 2170 cells found in other Tesla models, rather than the much-touted 4680 battery, which is still facing production challenges. So, how does it manage such quick charging?
Subsection 1.1.1: The Science Behind Rapid Charging
Tesla optimizes charging by allowing all cells to charge simultaneously rather than sequentially. The Semi's battery is equivalent to ten Model S battery packs, which can collectively achieve a maximum charging rate of 250 kW. If ten Model S vehicles are charging at different superchargers, they would collectively draw 2.5 MW. The Semi operates similarly but at a slower pace.
The challenge lies in how to transfer such significant power through a single cable. Electrical power is the product of voltage and current; thus, increasing either factor enhances the overall power output. While high currents can generate excessive heat, leading to potential hazards, higher voltages mitigate this issue. Consequently, Tesla's strategy involves utilizing higher voltage chargers to achieve 1 MW charging rates.
For effective charging, a battery must be charged at a voltage that aligns with its output. Therefore, the Semi's battery operates at 1,000 volts, significantly higher than Tesla's standard 350 volts.
Section 1.2: Cybertruck's Compact Power Source
The Cybertruck's battery, reported to be 200 kWh, is notably smaller than the Semi's. Using the Model S as a benchmark, it should ideally charge at 500 kW. However, Tesla has ingeniously wired the Cybertruck’s battery to accommodate higher voltage, allowing it to receive more power safely.
Nonetheless, wiring for higher voltages can reduce the amount of current a battery can supply, which is critical for an EV’s torque. Fortunately, at 200 kWh, the Cybertruck's battery is sufficiently robust to deliver adequate power, even with higher voltage wiring.
Chapter 2: The Competitive Landscape
Tesla's approach to high-voltage battery systems comes with increased production costs. Constructing a 200 kWh system requires more cells and stricter safety measures, driving up expenses. Additionally, most charging stations do not deliver high voltages, necessitating the inclusion of expensive transformers in the vehicle to utilize standard stations.
However, Tesla's innovative designs allow for cost-effective manufacturing of these larger battery packs, ensuring the Cybertruck remains competitively priced between $40,000 and $70,000. While competitors could replicate this technology, their versions would likely be pricier due to less efficient designs and production processes.
Musk has also indicated plans to introduce 1 MW charging capabilities at Tesla's supercharger stations next year, suggesting that these stations could facilitate such rapid charging. This means Cybertruck owners will enjoy these extraordinary charge speeds, while other manufacturers may not have access to the same high-voltage infrastructure.

In conclusion, I must acknowledge my earlier misjudgment regarding Tesla's technological standing in the EV industry. The Cybertruck proves that Tesla remains significantly ahead of the competition—provided Musk can successfully launch its production.
