What is the reason for BYD not starting?

It may be due to a dead battery or a faulty spark plug. Here are the relevant explanations: 1. Battery: A battery is a type of storage battery, also known as an accumulator, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and sulfuric acid solution as the electrolyte. 2. Spark plug: The spark plug is an important component of the gasoline engine ignition system. It introduces high voltage into the combustion chamber and causes it to jump across the electrode gap to produce a spark, thereby igniting the combustible mixture in the cylinder. It mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell.
My BYD also had a no-start issue last week, and after struggling for a while, I found out it was due to a dead battery. This situation is actually quite common - either the battery is aging and losing its charging capacity, or you forgot to turn off the lights and drained the battery. If turning the key gives no response at all, first check if the battery terminals are oxidized or loose, as poor contact can also cause this. For automatic transmission cars, also verify it's in P gear - incorrect gear position can prevent starting. Additionally, don't overlook smart key issues; when the key battery is dead or there's signal interference, the car can't detect the start signal. I recommend keeping an emergency jump starter in your car - it can save you in such situations.
A friend who runs a repair shop mentioned that if a BYD car won't start, there's an 80% chance it's due to a battery issue. Especially in winter when temperatures are low, insufficient battery voltage can completely fail to power the starter motor. However, if the starter makes a clicking sound but doesn't turn, it might be due to worn starter carbon brushes or a faulty solenoid switch. Also, pay attention to the fuse box—a blown fuse responsible for starting can cause a complete power loss in the vehicle. Previously, we encountered a customer's car where the steering wheel lock jammed the ignition switch; in such cases, simply turning the steering wheel left and right while turning the key can resolve the issue. Lastly, a reminder: for hybrid models, also check the condition of the auxiliary battery, as it powers the starting system.
