What Does It Mean When the Ignition Switch Is On?

Why Are More and More Cars Without Independent Roof Antennas?

Because independent antennas have drawbacks, they are gradually exiting the mainstream market. Older cars used telescopic antennas, similar to those on old radios that could extend and retract, but modern cars have largely abandoned this type of antenna. Whip antennas, which are non-retractable, are now more commonly used in cars. They look aesthetically pleasing but generate significant wind noise. Glass antennas, embedded within the front or rear windshield, are another option, making the small tail-like protrusion invisible. Glass antennas have become a mainstream configuration. Since glass antennas meet the requirements of automotive mechanics, aesthetics, and aerodynamics, many manufacturers prefer this option.

What to Do If You Lose One of Two Car Keys?

It is recommended to replace all car locks to prevent vehicle theft. After going to a service station to set the lost key as an illegal key, this key can no longer start the vehicle but can still open the doors, posing a risk of valuable items being stolen. Here are some precautions for storing car keys: Remove the key promptly: If you need to leave the car, even for just a few minutes, do not leave the key in the ignition. Always turn off the engine, lock the car, take the key with you, and close all windows and sunroofs tightly to avoid giving thieves an opportunity. Do not keep the spare key in the car: Do not store the spare key inside the car. Most modern car anti-theft systems are designed to protect the engine. Even if a thief duplicates a key to open the doors, they cannot start the engine and drive away. However, the spare key can ignite the engine, so it must never be left inside the car, nor should it be used as a regular key for long-term use. Understand insurance coverage: When purchasing car insurance, familiarize yourself with the details of theft-related compensation to ensure you have the necessary evidence for claims in case the vehicle is stolen after losing the keys.

High energy density can bring good durability to electric vehicles. Secondly, the lifespan, output power, and cost control of ternary lithium batteries can achieve a certain balance, which is conducive to the popularization of commercialization. Leading companies in the power industry such as Tesla, BYD, and BAIC New Energy mostly use ternary lithium batteries in their products. The advantages of fuel cells are obvious. In principle, there is no difference between solid-state batteries and ternary lithium batteries, except that the liquid electrolyte is replaced by a solid one.
