Key Features of the New CATL Battery

The 4C charging rate is not just a minor improvement, it’s a monumental leap that could redefine public perception of electric vehicle usability. With such fast charging capabilities, electric vehicles equipped with CATL’s new battery could see a significant advantage over internal combustion engine vehicles, especially for long-distance travel.

Understanding the 4C Charging Rate

One of the most eye-catching features of CATL’s new lithium-ion phosphate battery is its 4C charging rate. For those unfamiliar with battery terminology, the “C rate” is a measure used to describe the charging or discharging speed of a battery in relation to its capacity. A 4C rate implies that the battery can be fully charged or discharged in just 15 minutes. This is a significant advancement, especially when you consider that most current EV batteries have C rates that allow for full charging in hours, not minutes.

Current Tesla’s Charging Speed

To put this into perspective, let’s compare it with Tesla’s existing charging capabilities. Tesla’s Superchargers, which are among the fastest public chargers available, offer rates up to 250 kW for some models. Even Tesla’s V3 Superchargers, designed for rapid charging, do not come close to the 400 kW that a 4C rate would imply for a 100-kWh battery pack.

For example, the Old Tesla Model 3 Long Range, which has a battery pack of approximately 82 kWh, can charge at a maximum rate of around 250 kW at a V3 Supercharger. This is impressive but still falls short of the 328 kW that a 4C rate would imply for this particular battery size.

The implications are clear: If Tesla were to adopt CATL’s new battery technology, it could potentially cut down charging times dramatically, making long road trips more convenient and further reducing “range anxiety” among potential EV buyers.

CATL Energy Density and Range

CATL’s new lithium-ion phosphate battery technology offers a trifecta of benefits: fast charging capabilities, increased energy density, and improved cold-weather performance. These features could have a transformative impact on Tesla’s electric vehicle lineup, making them more efficient, longer-lasting, and convenient for consumers

CATL Battery Range

Another groundbreaking feature of CATL’s new lithium-ion phosphate battery is its claimed range of over 700 kilometers (around 435 miles) on a single full charge. Traditionally, lithium-ion phosphate batteries have been less energy-dense compared to their nickel-based counterparts, making them less suitable for long-range electric vehicles. However, CATL’s new technology seems to have overcome this limitation, offering a range that rivals even the most energy-dense nickel-based batteries.

Potential Impact on Tesla Cars

To understand the potential impact on Tesla, let’s consider the Tesla Model 3, which currently uses a lithium-ion phosphate battery sourced from CATL for its Standard Range Plus variant. The vehicle has an EPA-rated range of 272 miles (around 438 kilometers). If Tesla were to implement CATL’s new battery technology, it could see a significant increase in range. A 21% increase, for instance, would push the Model 3’s range to approximately 329 miles, making it competitive with Tesla’s long-range models and further broadening its appeal to consumers concerned about range.

Cold Weather Performance

One of the significant drawbacks of traditional lithium-ion phosphate batteries is their performance in cold weather. Lower temperatures can affect both the charging speed and the acceleration of electric vehicles. CATL’s new battery technology promises to change this narrative. According to CATL, the new battery can charge from zero to 80% in just 30 minutes at temperatures as low as -10 degrees Celsius (14 degrees Fahrenheit).
