What does new energy EV mean?

EV stands for Electric Vehicle, which literally translates to electric car. Essentially, all vehicle models powered by electric motors can be referred to as EVs. Below is a relevant introduction to new energy vehicle types: 1. HEV: Hybrid Electric Vehicle, abbreviated as HEV or HV, is a hybrid vehicle that relies on both fuel and batteries to provide energy. Hybrid vehicles add batteries and electric motors to conventional fuel-powered cars. The battery capacity is usually relatively small, but it does not require external charging as it automatically recharges by recovering energy during driving. Due to the small battery capacity, the main role of the electric motor is to assist the fuel engine during driving, achieving fuel savings and improving acceleration and uphill performance. The vehicle only enters pure electric mode when driving at low speeds. Currently, HEVs are the most commonly seen new energy vehicle models on the market, and governments worldwide also provide various subsidies for HEV models. 2. PHEV: PHEV stands for Plug-in Hybrid Electric Vehicle. The biggest difference between PHEV and HEV is that PHEV requires external charging via a socket or charging station. PHEVs have much larger battery capacities than HEVs, allowing for longer distances in pure electric mode. The electric motor and fuel engine complement each other; for example, fuel energy is used during high-speed driving, while electricity is used for starting or low-speed driving to improve efficiency. PHEVs also offer more mode options, such as using pure electric mode in urban areas and switching to fuel mode when the battery is depleted, which can save more fuel. Another advantage of PHEVs is that there is no worry about being unable to drive when the battery is depleted (a problem with pure electric vehicles), as the vehicle can still operate normally using fuel when the battery is empty.

What Does It Mean When the Coolant Light Comes On?

Reasons for the coolant light coming on: 1. Low coolant level, which typically occurs right after starting the engine, can be resolved by simply adding more coolant; 2. If the light comes on during driving, it may be due to coolant boiling. In this case, you can shift to neutral and coast to allow air cooling. Coolant, short for antifreeze coolant, is designed to prevent freezing in cold weather, thereby avoiding radiator cracks and engine cylinder block damage caused by frozen coolant. Coolant consists of three components: water, antifreeze, and additives. Based on the antifreeze agent used, it can be classified into alcohol-based, glycerol-based, and ethylene glycol-based coolants.

What Causes the Electronic Power Steering Wheel to Feel Heavy?

The reasons why the electronic power steering wheel feels heavy: 1. When the car's steering gear lacks lubrication, symptoms such as steering stiffness and a heavier steering wheel may occur. It is necessary to add lubricating oil, and in some cases, replace the power steering fluid; 2. When the tire pressure of the car is too low, the contact area between the tire and the ground increases, resulting in greater resistance during driving, making the steering wheel feel heavier. It is essential to inflate the tires promptly; 3. If the battery has been undercharged for a long time, the steering wheel will not receive assistance from the motor. In this case, the battery needs to be recharged; 4. If the car's electronic power assist fails, the steering wheel will become heavier, requiring inspection and repair at a 4S shop.

What are the reasons for the loud noise inside the Haval H2?

Haval H2's loud interior noise is due to engine damage, which can be categorized into two types: cold engine abnormal noise and hot engine abnormal noise. Cold engine abnormal noise refers to the unusual sounds emitted from the engine compartment when the car is parked, which automatically disappear after the car is warmed up. This happens because when the car is parked for a long time, the lubricating oil basically flows back to the oil pan. During a cold start, the oil pump cannot immediately establish oil pressure, and the oil film between components, especially the valves inside the cylinder head, cannot be lubricated during a cold start. Both hydraulic lifters and mechanical rocker arms will have a certain valve clearance, or the timing chain with insufficient oil pressure cannot work properly, resulting in a clicking sound. There are many reasons for hot engine abnormal noise, generally due to damaged or faulty car components. For example, the engine oil viscosity is too high, there is carbon buildup in the engine cylinders, or there is valve leakage, which require timely repairs.

How many years does it generally take for a vehicle to be scrapped?

Generally, vehicles are scrapped after 15 years, but currently, the scrapping of private cars has shifted from being based on years to mileage, with a maximum mileage of 600,000 kilometers. Starting from May 1, 2013, old vehicles were phased out according to new regulations, which eliminated the scrapping age limit for private cars, setting a maximum mileage of 600,000 kilometers. The regulations stipulate that small and micro non-operational passenger cars, large non-operational vehicles, and wheeled special-purpose machinery vehicles have no usage age limit. The new retirement age regulations for household vehicles removed the driving age limit for non-operational cars as officially released by the Ministry of Commerce in the "Mandatory Scrapping Standards for Motor Vehicles," limiting private cars to 600,000 kilometers. This mileage-based restriction, instead of a year-based one, significantly improves vehicle utilization. Data: The extension of the retirement age for household vehicles imposes higher requirements on the safety and technical inspections of vehicles. Under the new policy, private cars require two annual inspections starting from the 15th year after registration, and those over 20 years old require four annual inspections starting from the 21st year. During annual inspections, strict regulations apply to older vehicles. When inspecting the power of private cars, the chassis output power must not be less than 60% of the engine's rated power or 65% of the maximum net power. Additionally, according to the new standards, vehicles that fail to meet safety standards and do not comply with environmental standards within one inspection cycle will be forcibly scrapped. The power inspection project will also replace the existing fuel consumption project, phasing out vehicles with poor performance indicators. Therefore, while the usage age of vehicles has been relaxed, the elimination of older vehicles has been strengthened, especially with stricter control over environmental standards.
