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.

Honestly, driving a new energy vehicle comes with major range anxiety. My daily commute is manageable, but long-distance trips make me nervous. Even fully charged, an electric car only runs 400-500 kilometers, and the battery drains rapidly if stuck in traffic or using air conditioning on highways. Finding charging stations is a hassle, especially in rural areas where detours are often needed to locate a charger. Fast charging still takes over 30 minutes, making the wait tedious. Winter is worse, with range dropping another 20%. The higher price tag—tens of thousands more than gas cars—takes years of fuel savings to offset. Then there’s the exorbitant battery replacement cost: after 5-6 years, battery degradation can mean a replacement costing thousands. Overall, convenience takes a hit, and keeping a gas car as a backup is far more reassuring.

New energy vehicles save money? Not necessarily. When I chose an electric car, I focused on this point, but the actual expenses were unexpected. The down payment was expensive, still 20% higher even after subsidies, and the loan interest was significantly more. Insurance is also costly, costing hundreds to thousands more per year due to the high risk of battery repairs. Maintenance is simpler with less oil changes, but a battery failure means a huge expense—replacing one easily exceeds 50,000. Then there’s charging costs; during peak hours when electricity prices rise, a full charge isn’t much cheaper than filling up with gas. The used car market is even worse, with rapid depreciation—selling after three years means losing over half the value. Overall, the total expenses aren’t cost-effective, so don’t act impulsively without a solid budget.

Are new energy vehicles really eco-friendly? As someone who cares about sustainability, I don't think electric cars are completely green. Battery production causes significant pollution - lithium battery manufacturing requires mining, which leads to soil/water damage and carbon emissions. Not to mention the recycling challenges - improper disposal of used batteries can leak toxic chemicals and pollute the environment. The electricity source isn't clean either, with some regions relying on coal power, meaning driving EVs might actually increase carbon footprints. Short battery lifespans requiring frequent replacements also waste resources. Overall, at this stage they're not thorough enough in reducing emissions - looking forward to technological advancements solving these issues.

From a technical perspective, new energy vehicles have their shortcomings, particularly in terms of range and batteries. As an electric vehicle owner, I've experienced battery capacity degradation by a few percent each year. After about six years, the range noticeably shrinks, affecting daily commutes. Charging efficiency is another issue—fast-charging stations are scarce, and a full charge takes several times longer than refueling a gasoline car, which is a significant time drain. Performance worsens in cold weather, with faster battery depletion and increased energy consumption when using the heater, raising the risk of being stranded. Repairs often require specialized shops, meaning even minor issues necessitate a trip to the dealership, which is costly and inconvenient. Without a stable power source, charging can fail due to grid instability.
