What is the maximum power of a new energy vehicle?
2 Answers
The maximum power of new energy vehicles is 115kW. Engine maximum power: The maximum power of the engine is the decisive factor in determining the top speed of a car. As the saying goes, 'Acceleration depends on torque, while top speed depends on power.' If the engine power is very small and the car is heavy, it will result in a situation where a small horse pulls a big cart, and the car's top speed will certainly not be high. Only when the engine outputs its maximum power and the car is traveling at a constant speed, the speed at this time is the highest speed. Air resistance encountered by a car at high speeds: Among the various driving resistances of a car, air resistance has the greatest impact on the car. According to tests, when the car speed exceeds 120 km/h, air resistance accounts for about 80% of the total driving resistance; when the speed exceeds 180 km/h, the resistance encountered by the car is almost entirely air resistance, and other resistances can be negligible in comparison.
As an ordinary owner who has driven a new energy vehicle for several years, I find that the maximum power can vary quite a bit, typically ranging from 120kW to 300kW. For instance, my Tesla Model 3 has 250kW, which provides quick acceleration and makes city driving effortless. However, high-performance models like the top-tier Porsche Taycan can exceed 500kW, but the trade-off is faster battery drain, especially when using the heater in winter. When choosing a car, it's essential to consider actual needs—100kW is sufficient for city commuting, while higher power is only necessary for long trips or speed enthusiasts. Additionally, higher power demands more from charging, requiring fast-charging stations to avoid long waits, which impacts daily convenience. Overall, balancing power and range is an art—don’t just focus on the numbers.
