What is the Difference Between Electric Vehicles and Automatic Transmission Vehicles?
2 Answers
Electric vehicles and automatic transmission vehicles differ in the following aspects: 1. Different Structures: Structurally, pure electric vehicles rely on the three-electric system as the power source, lacking components like transmissions in their powertrain. According to the working principle of pure electric vehicles, they operate by supplying electrical energy from the battery to the motor, which drives the vehicle forward. 2. Different Power Characteristics: The motor adjusts its speed range and torque output by controlling the current size during operation, enabling it to adapt to all speed ranges under varying current and voltage conditions. Electric vehicles achieve acceleration and deceleration without the need for a transmission to convert power, eliminating the need for manual physical intervention in the vehicle's transmission to achieve speed conversion.
The biggest difference between electric vehicles (EVs) and automatic transmission cars lies in their power source and driving mechanism. EVs rely on batteries and electric motors for propulsion, completely eliminating the need for gasoline, which results in exceptionally quiet and smooth starts without any gear-shifting jerks. In contrast, automatic transmission cars are typically gasoline-powered, equipped with engines and gearboxes that shift gears automatically without manual intervention, though engine noise may be noticeable during startup.
From a daily usage perspective, EVs offer convenient charging—I simply plug in at night and wake up to a fully charged battery, saving trips to gas stations. Automatic cars require regular refueling, which is more expensive; on average, electricity costs per 100 kilometers are significantly lower than fuel expenses. Maintenance-wise, EVs involve far fewer hassles, eliminating concerns like engine oil or spark plugs—basically just brake pads need attention. Automatic cars require transmission fluid changes and, if mishandled, costly and time-consuming transmission repairs.
However, battery lifespan is a concern. After five or six years of EV ownership, battery replacement becomes a consideration, carrying high costs, whereas well-maintained automatic car engines can last longer. Overall, both eliminate gear-shifting hassles, but EVs stand out for being more eco-friendly and energy-efficient.
