Can New Energy Vehicles Charge Outdoors on Rainy Days?

New energy vehicles can charge outdoors on rainy days. Here are some extended details: 1. Waterproof performance standards for charging piles: During the construction of charging piles, waterproof materials are applied to the bottom of the charging facilities, ensuring that the lower 20~30 cm of the charging pile body has flood-resistant capabilities. National standards for the waterproof performance of charging piles are very strict. Before charging begins, both the vehicle side and the pile side must undergo insulation testing. If the insulation test fails (due to rain or debris), charging cannot be initiated. 2. Materials of charging piles: Most charging piles are made of SMC fiberglass, which ensures long-term outdoor use and resistance to complex weather conditions. Additionally, modern charging piles are internet-connected, allowing their operational status to be monitored in real-time via a backend system. If any issues or malfunctions occur, alerts can be received immediately in the backend, ensuring charging safety. Even though charging piles are equipped with waterproof materials, it is recommended to avoid charging during heavy rain.

Can You Still Drive If Water Gets Inside the Car?

You should not drive if water gets inside the car. Here are the details about water ingress in a car: 1. Scenario One: You can still drive, but if the air filter gets wet, the engine may draw in some water into the intake tract, forming water vapor. This vapor mixes with gasoline and burns completely, causing minimal impact on the engine. 2. Scenario Two: A small amount of water enters the engine and mixes with the oil, degrading the oil quality. Oil contaminated with water increases wear on engine components, potentially leading to louder engine noise and greater vibration in the future. 3. Scenario Three: The engine starts but shuts off after a few seconds, and subsequent attempts fail to restart it. This is the most severe scenario. Since water cannot be compressed, its presence in the cylinders during high-speed operation can cause the valves and connecting rods to bend, the pistons to seize, severe cylinder wear, and crankshaft bending.

Why don't sedans have rear tow hooks?

Only the hooks at the rear of off-road vehicles are called tow hooks, which are used for towing trailers or caravans. For regular vehicles, they have tow rings for rescue purposes, located at both the front and rear. Many vehicles have their tow hook positions designed at the lower part of the bumper, and the exact location is usually indicated in the vehicle's user manual. Here is some additional information: 1. Tow ring location: The tow rings on sedans are hidden within the front and rear bumpers. There is a small cover on the bumper that can be removed to reveal the tow ring. For many sedans, the tow ring is a threaded hole, and the vehicle's toolkit includes a tow ring that can be screwed in for use. 2. Function: A car tow hook is a spherical towing device. Nowadays, most vehicles abroad are equipped with a tow hook system, and many car brands come with tow hooks as standard. Car tow hooks have become an essential component of vehicles. In case a vehicle being towed accidentally detaches from the tow hook while driving, a steel cable can prevent the towed vehicle from moving uncontrollably, thereby avoiding potential accidents.

What does it mean when the ETC tag shows as invalid?

When 'Tag Invalid' appears on the ETC, it indicates that the ETC electronic tag is not activated. You need to take the ETC device to an ETC service center or ETC service outlet for inspection. If the invalidation is not caused by human factors, a simple ETC reactivation will allow it to be used again. How ETC works: ETC operates through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations. It uses computer networking technology to process background settlements with banks, enabling vehicles to pass through highway or bridge toll stations without stopping to pay fees. Where ETC can be installed: For small vehicles like cars and minivans, the ETC card and OBU device are installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part.

How Often Should Tires Be Replaced During Car Maintenance?

Generally, tires should be replaced every 3 to 5 years or after 60,000 to 100,000 kilometers during car maintenance. Tires are one of the most critical components of a vehicle, directly impacting its performance and driving safety. Since tires are in constant contact with the ground, they inevitably wear out over time, necessitating regular maintenance and replacement. Below is some essential information about car tires: 1. Tires operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during driving. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption. Additionally, they need to exhibit high wear resistance, flexibility, low rolling resistance, and minimal heat generation. 2. The primary functions of tires include: supporting the vehicle's entire weight and bearing its load; transmitting traction and braking torque to ensure proper adhesion between the wheels and the road surface; dampening and absorbing vibrations and impacts during driving to prevent excessive stress and premature damage to vehicle components; enhancing high-speed performance while reducing noise levels; and ensuring driving safety, handling stability, comfort, and fuel efficiency.
