Battery performance can be assessed through external inspection, checking the electrolyte level, measuring the terminal voltage, testing the electrolyte concentration, and evaluating the battery's discharge level. Generally, a faulty battery will exhibit abnormalities in these tests. Relevant information about automotive batteries is as follows: 1. Introduction: An automotive battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. Typically, the term "battery" refers to a lead-acid battery, which is primarily made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Working Principle: It uses lead plates filled with sponge lead as the negative electrode and lead plates filled with lead dioxide as the positive electrode, with a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.

Will the engine malfunction indicator light illuminate when the Chery E5 is powered on?

When the Chery E5 is powered on, the engine malfunction indicator light will illuminate during the vehicle's self-check upon starting. If the engine is functioning normally, the light will automatically turn off after the engine starts. Principle of the engine malfunction light: The engine malfunction signal is issued by the engine control unit (ECU), which governs all electronic components of the engine, including the electronic throttle, fuel injectors, alternator, fuel pump, etc., covering systems such as intake, exhaust, fuel, ignition, and timing. If the engine malfunction light illuminates, it indicates an abnormality in a specific system. To determine the exact issue, a diagnostic scanner must be used, as each vehicle brand has its own unique fault codes. Persistent engine malfunction light: If the engine malfunction light remains illuminated and does not turn off, it signifies that the engine parameters have deviated from normal. Excessive carbon buildup is a common cause of such parameter changes. If this issue is not addressed, the engine's combustion state cannot be adjusted back to normal, and the malfunction light will remain on without automatically disappearing.

What does it mean when the car battery light is on?

The battery light on the car indicates a fault in the charging system. At this time, the battery is not charging but only discharging, and you need to stop the car immediately because all the electricity used in the car comes from the battery. When the battery is exhausted, the car will automatically shut down and cannot be driven. The battery indicator light is used to display the working status of the car battery, and its color is usually red or yellow. When you turn the key and the vehicle performs a self-check, this indicator light will come on. After starting the car, the indicator light will automatically turn off. The car battery, also called a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Batteries are divided into ordinary batteries, dry-charged batteries, and maintenance-free batteries. Usually, when people refer to a car battery, they mean a lead-acid battery. The normal service life of a car battery varies from 1 to 8 years, which is closely related to the condition of the vehicle.

Where to Find the Vehicle Compliance Certificate Number?

The vehicle compliance certificate number can be found on the vehicle compliance certificate, located in the upper right corner of the first page of the motor vehicle registration certificate, consisting of 17 digits. The vehicle compliance certificate is issued with the vehicle upon leaving the factory. It needs to be submitted to the vehicle management office for archiving during the vehicle registration process, and the motor vehicle registration certificate is then replaced. Therefore, the compliance certificate for unlicensed vehicles should be in the hands of the dealer, while for licensed vehicles, it is stored in the archives of the vehicle management office. The vehicle compliance certificate is an important document for the vehicle and is essential for vehicle registration. Only vehicles with a compliance certificate meet the national requirements for motor vehicle equipment quality and related standards. National regulations stipulate that the compliance certificate for a new vehicle must accompany the vehicle at all times, meaning the certificate arrives when the vehicle does, and it should be taken away together with the vehicle upon delivery.
