The Maisotsenko Cycle (M-Cycle) is a cooling technology that increases electric car cables’ capacity to 2000 A-10000 A, reducing charging times to less than 1 minute with suitable batteries and components. Alexey Polyakov, General Manager of Air To MC2—Maisotsenko Cycle Air Cooling, discusses methods to tackle slow charging due to inadequate cable cooling.

The adoption of electric vehicles faces a considerable challenge due to slow charging at charging stations caused by inadequate cable cooling. Current commercial charger capacity is restricted to 500 A due to thermal constraints. Technologies like liquid-cooled charging cable systems for fast EV charging can charge 500 Amperes in 15 minutes.

The Maisotsenko Cycle (M-Cycle) is a unique cooling technology that can cool electric car cables, increasing current capacity to 2000 A-10000 A. It is expected that EV charging times will be reduced to less than 1 minute with appropriate batteries and components. The M-Cycle uses evaporative cooling to cool and remove heat from charging cables. This allows for a higher current capacity than existing ultra-fast charging cables and improves the customer experience.

The M-Cycle has unique properties which cool any subject from its highest temperature (100°C, 500°C, or 1000°C) to the dew point temperature of the ambient air. The heat extracted from the electrical charging cable is not wasted but instead converted into additional cooling capacity for better efficiency. The M-Cycle cooling system excels at high temperatures and heat fluxes, making it ideal for cooling charging cables. It can handle heat levels beyond current technologies’ capabilities, demonstrating its unique ability to cool objects at extremely high temperatures and heat fluxes.

Electric vehicles are replacing traditional ones at a rapid pace. The world is thus focusing on high-power charging standards for medium- and heavy-duty vehicles, such as Megawatt Charging Systems (MCS). The Megawatt Charging System (MCS) is a high-power connector standard for charging large electric vehicles (EVs) like trucks, buses, and heavy-duty equipment. It can deliver up to 3.75 MW of charging power, reducing charging time for these vehicles. MCS is anticipated to contribute to electric commercial transportation, decrease fossil fuel usage, and promote sustainability in logistics and heavy industries.
