Disadvantages of hybrid hybrid hybrid

There are two sets of power, combined with two sets of power management and control systems, which have a complex structure, difficult technology, and high prices. After years of research, hybrid electric vehicles have developed some successful examples. In December 1997, Toyota Motor Corporation of Japan announced to put the hybrid electric car Prius into small batch commercial production. The car has a dead weight of 1515kg, is equipped with a four cylinder overhead camshaft, 1500cc displacement gasoline engine, the maximum power is 42.6kW/4600r/min, and is equipped with a permanent magnet brushless generator. The drive motor is also a permanent magnet brushless rated power of 30kW. It uses nickel hydrogen battery to realize series parallel control. The fuel consumption per hundred kilometers is 3.4L, which is half of the original gasoline vehicle, The CO2 emissions have also been reduced by half, with CO, HC, and NOX only accounting for 10% of the allowable values under current regulations, with a selling price of 2.16 million yen (approximately $15000) per vehicle. In February 1998, Chrysler Motor Company of the United States exhibited the second generation Dodge dreadnought ESX2 hybrid electric sedan in Detroit. The car is equipped with a 1500cc displacement direct injection diesel engine with a generator, a lead-acid battery, AC induction motor drive, an aluminum frame, and a composite body. The self weight is 1022kg, and the fuel consumption per 100 kilometers is reduced to 3.4L. In 2000, General Motors, Ford, and Daimler Chrysler had developed prototypes of cars with a fuel consumption of 3 liters of gasoline or close to 3 liters per 100 kilometers, but the prices were still relatively expensive.
