Lithium batteries are resistant to high temperatures inside vehicles. Here is a detailed introduction about lithium batteries: 1. Overview: Lithium batteries are lighter in weight, have relatively high energy density, good performance, and a wide range of applications. 2. Classification: There are two types of lithium batteries commonly used in pure electric vehicles, one is ternary lithium batteries, and the other is lithium iron phosphate batteries. 3. Lithium iron phosphate batteries vs ternary lithium batteries: The positive electrode of lithium iron phosphate batteries is made of lithium iron phosphate, which has a higher safety factor than ternary lithium batteries. However, the energy density of lithium iron phosphate batteries is lower than that of ternary lithium batteries, and their low-temperature performance is not necessarily better than that of ternary lithium batteries.
I've been driving for over ten years and have encountered dim headlights several times. The most common issue is a burnt-out bulb; after prolonged use, the filament breaks and it's a straightforward replacement. Blown fuses are also frequent—there's a diagram in the fuse box, making it easy to locate and replace the correct one. Poor wiring connections are annoying; loose contacts cause flickering lights, especially prone to short circuits on rainy days. If the relay or combination switch fails, the lights won't turn on and require professional inspection. Overvoltage from the alternator keeps burning out bulbs, necessitating voltage testing and adjustment. Safety is paramount—I recommend pulling over immediately if headlights fail at night, turning on hazard lights, and calling for roadside assistance or a tow to a repair shop. Last month, my old car's lights suddenly died on the highway; thankfully, the emergency lights worked, allowing a safe stop—later diagnosed as aged wiring. Regular maintenance should include checking the lighting system, prioritizing prevention.
