What is the voltage of an electric vehicle?

Electric vehicles generally operate at 336V or 384V, while electric buses typically have a bus voltage of 580-600V. The higher the bus voltage, the wider the constant power speed range of the motor. Voltage (V): Electric vehicles generally operate at 336V or 384V, while electric buses typically have a bus voltage of 580-600V. The higher the bus voltage, the wider the constant power speed range of the motor. On-board power source: A pure electric vehicle refers to a vehicle that uses an on-board power source as its power, meeting all the requirements of road traffic and safety regulations. Due to its relatively smaller environmental impact compared to traditional vehicles, its prospects are widely optimistic, but the current technology is still not mature. A pure electric vehicle (Battery Electric Vehicle, abbreviated as BEV) is entirely powered by rechargeable batteries (such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, or lithium-ion batteries). Although it has a long history of 134 years, its application has been limited to certain specific areas, mainly due to the serious shortcomings of various types of batteries, including high cost, short lifespan, large size and weight, and long charging time.

What to Do If You Didn't Take the Toll Card on the Highway?

If you didn't take the toll card when entering the highway, you can still be charged based on the actual mileage by providing relevant proof (specifically, proof of the entry point). During free holiday periods, even if you didn't take the toll card upon entry, you won't be charged at the exit. Some drivers have encountered situations where the automatic card dispenser issued two toll cards. In such cases, the driver can inform the toll collector, return both cards, and request a new one. If the driver fails to return the card immediately, they can proactively explain the situation to the toll collector when paying at the exit. After verification, the normal toll will be charged. If you took the card but didn't return it at the exit and were caught by staff, it will be considered as evading the toll, and you may be blacklisted. You'll need to pay the toll for the longest possible distance the next time you use the highway. If you took the card and left the highway without being noticed, congratulations—you've got a free souvenir toll card.

How to Drive the Most Fuel-Efficiently?

Press the accelerator pedal lightly, avoid sudden acceleration, minimize braking and acceleration, and maintain a steady speed as much as possible within the number of restarts. Do not keep the accelerator pedal in one position for a long time. Maintaining good driving habits can maximize fuel economy. In fact, besides the inherent displacement of the car itself, the driver's poor driving habits are closely related to the car's fuel economy. Poor driving habits not only waste fuel but also cause unnecessary damage to the vehicle. For example, some people like to keep their left foot on the clutch while driving, which not only increases clutch wear but also causes unnecessary power loss. "Coasting in neutral saves fuel" only applies to older carburetor models. Many modern fuel-injected engine models do not benefit from this method at all and may even consume more fuel. When coasting in neutral (especially at high speeds), the lubrication effect of the transmission deteriorates, which is harmful to the transmission. Moreover, from a safety perspective, coasting in neutral causes the vehicle to lose power, making it like a kite with a broken string. Once the engine idles, the car's power steering stops working, which can easily lead to traffic accidents.

Should You Use Internal or External Air Circulation on Rainy Days?

It is recommended to use external air circulation in the car on rainy days. When the weather is cold during rainy days, both side windows can fog up, obstructing the driver's vision. Therefore, first use the external air circulation to adjust the airflow towards the windshield, then switch to external circulation to expel the steam exhaled by passengers out of the car. Introduction to External Circulation: External circulation mode uses a fan to draw outside air into the car, meaning the airflow between the outside and inside of the car is connected. The air blown by the fan comes from outside the car, and even if the fan is turned off, airflow is still drawn into the car while driving, replenishing fresh air inside. Sometimes, you may feel airflow even when the fan is off, which is because the external circulation is set. When driving in the city and encountering traffic congestion, the car may fill with exhaust fumes, which is caused by using external circulation. When to Use External Circulation: When using internal circulation for an extended period and it's inconvenient to open the windows, you can periodically switch to external circulation to bring fresh air into the car. When there are many passengers in the car, using external circulation can maintain fresh air and prevent excessive humidity inside the car from causing window fogging.

Do imported cars have certificates of conformity?

Imported cars require certificates of conformity. However, due to different business practices, some certificates come with the vehicle while others may take a long time to be provided. When purchasing a car, it's important to pay attention to some crucial documents. For example, the purchase invoice is one of the most important documents when buying a car and is an essential certificate for vehicle registration. Whether it's a new or used car, as long as it involves a transaction, there will be a purchase invoice. After all, a car is a consumer product, and the invoice serves as important evidence for any future disputes. The certificate of conformity is another crucial document for a car and is also required for vehicle registration. Only cars with a certificate of conformity meet the national requirements for motor vehicle equipment quality and related standards, thus qualifying them to be driven on the road. The "three guarantees" cover many detailed aspects and protect consumer rights. For instance, within 60 days from the date of the purchase invoice or within 3,000 kilometers driven, if major components like the engine or transmission have quality issues, consumers can apply for free replacement of the corresponding parts. This serves as an important document for post-purchase consumer protection.
