What are the disadvantages of new energy vehicles?
1 Answers
New energy vehicles have the following disadvantages: 1. The system structure is relatively complex. 2. The fuel-saving effect is not obvious during long-distance high-speed driving. 3. Low cost-effectiveness: The energy stored per unit weight of the battery is too low, and since the batteries for electric vehicles are expensive and have not yet achieved economies of scale, the purchase price is relatively high. As for usage costs, some trial results show that they are more expensive than conventional cars, while others are only 1/7 to 1/3 of the cost of conventional cars, depending mainly on battery lifespan and local fuel and electricity prices. 4. High maintenance costs: Due to the complex manufacturing process, maintenance is relatively troublesome, time-consuming, labor-intensive, and expensive.
