Electric vehicles (BEV) refer to vehicles that use on-board power sources as their driving force, with electric motors driving the wheels, meeting all the requirements of road traffic and safety regulations. Working principle: Battery – Current – Power regulator – Motor – Power transmission system – Driving the vehicle (Road). Types of electric vehicles: Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), Fuel Cell Electric Vehicles (FCEV). The amount of electricity required to charge an electric vehicle depends on the specific model. It mainly depends on two factors: The capacity of the lithium battery configured in the electric vehicle. The remaining battery percentage before charging. For example, if an electric vehicle's battery capacity is 20KWH and it has 50% remaining before charging, then only 10KWH is needed to fully charge it. Battery capacity is measured in KWH, where 1KWH = 1 kilowatt-hour of electricity. Therefore, the number of KWH a battery has represents how much electricity it can output, and conversely, it also needs the same amount to be fully charged.

Is it illegal to modify a car's steering wheel?

Modifying a car's steering wheel is not illegal. Here is the relevant information: 1. Introduction: A steering wheel is a wheel-shaped device used to control the direction of a car. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. 2. Function: The steering wheel is generally connected to the steering shaft via splines. Using a steering wheel with a larger diameter reduces the force required from the driver when turning. The steering intermediate shaft, as a connecting component between the steering gear and the steering shaft, facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and makes the installation of the steering gear and steering wheel more reasonable in the vehicle.

What are the three elements in an automotive three-way catalyst?

Three-way refers to the three precious metals: platinum (Pt), rhodium (Rh), and palladium (Pd), hence the name three-way. Relevant explanations are as follows: 1. Introduction: The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. The three-way catalyst converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. 2. Supplementary explanation: The three-way catalytic converter also contains certain purifying agents. When toxic gases pass through the exhaust pipe, the three-way catalytic converter releases these purifying agents onto the carrier, forming a catalytic effect to purify the toxic gases.

Is It Necessary to Use Iridium Spark Plugs in Regular Cars?

Regular cars can switch to iridium spark plugs, which can increase power and also reduce fuel consumption. What are spark plugs made of: Spark plugs mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. What types of spark plugs are there: Main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Replacement cycle for spark plugs: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

What are the items for vehicle annual inspection lighting?

Vehicle annual inspection lighting includes two major categories: external lighting and signal devices. Below are the relevant details: 1. Introduction: Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates, equivalent to an annual physical examination for vehicles according to the "Technical Conditions for Motor Vehicle Operation Safety." 2. Lighting requirements: Front lighting and signal devices such as headlights, front position lights, front turn signals, front hazard warning signals, clearance lights, and towing trailer marker lights should be complete and functioning properly; the high and low beam switching function of headlights should work normally; rear position lights, rear turn signals, rear hazard warning signals, clearance lights, brake lights, rear fog lights, rear license plate lights, reverse lights, and rear reflectors should be complete and functioning properly; the luminous intensity of brake lights should be significantly greater than that of rear position lights, etc.

How to Remove the Headlight Switch of a Volkswagen?

Feel below the connector with your hand to find the buckle, press it down to remove the wiring harness; 3. After unplugging the wiring harness, the headlight assembly will be removed. The Golf is a compact car under FAW-Volkswagen, with a length, width, and height of 4296 mm, 1788 mm, and 1471 mm respectively, and a wheelbase of 2636 mm. In terms of suspension, the front suspension of the Golf is a MacPherson independent suspension, and the rear suspension is a torsion beam non-independent suspension.

What is the difference between OEM and genuine auto parts?

The difference between OEM and genuine auto parts lies in their craftsmanship and appearance. Below are the relevant details: 1. OEM parts: OEM parts refer to those produced by the automobile manufacturer itself or authorized professional parts manufacturers. Genuine OEM auto parts are perfectly crafted, essentially matching the quality of the original components with no minor defects, and their appearance and performance are consistent with the original parts. They come with professional certification, bearing the OEM logo and part number. These are parts specifically provided by the automobile manufacturer for after-sales service. 2. Genuine parts: Genuine parts are produced by qualified manufacturers and fall under the category of aftermarket parts. However, the difference is that genuine parts carry the manufacturer's name, brand, and production certification, and are provided through formal channels. These manufacturers are included in the procurement list of automobile OEMs, ensuring quality and after-sales service. In terms of craftsmanship and appearance, they are slightly inferior to OEM parts.
