1. How does a battery create energy?
A battery is a device that converts chemical energy into electrical energy. Batteries create electrochemical energy by a chain of events that have to occur prior to the creation of electrical energy. Electricity is introduced into a battery via a charger. The charger acts as a conduit of the pushing electrons that are forcing their way into the chemical lithium. This charge process involves intercalation where electrons join with other molecules in the lithium’s minuscule spaces between the the lithium’s crystallized planes. Electrons are in essence ionizing lithium which loads the crystal planes to the point where they are forced into a current flow. Intercalation replenishes, in effect, lithium but the net result of ionization is the ultimate depletion of the lithium reactive property.
But what makes lithium good for batteries is that lithium is a highly reactive metal. Lithium has a very high electrochemical potential. In some lithium-based cells the electrochemical potential can be five times greater than an equivalent-sized lead-acid cell and three times greater than alkaline batteries. Lithium is also pliable and bendable allowing lithium to fit in tight configurations (perfect for in small cell designs in PDAs. Laptops, Cameras etc...).
2. Battery and an energy storage battery?
In the classification of battery usage scenarios, lithium-ion battery types are divided into consumer battery (3C batteries, used in mobile phones, notebook, digital cameras, etc.), power battery (new energy vehicles, light electric vehicles, electric tools, etc.), and energy storage system battery (power stations, communication base stations, etc.).
For power battery, it is actually a kind of energy storage system battery. However, due to the limitation of the size and weight of the car and the requirements of acceleration when starting, power battery has higher performance requirements than ordinary energy storage system battery, such as the energy density should be as high as possible, the charging speed of the battery should be fast, and the discharge current should be large.
3. Is it true that fast charging destroys the battery?
The battery life of a new energy vehicle is about 10 years, and it is expensive to replace a battery. New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new on-board power devices), the integration of advanced technologies in-vehicle power control and driving, and the formation of advanced technical principles and cars with new technology and new structure.
4. Does fast charging destroy the battery?
This importantly depends on battery density, battery material, battery temperature, and BMS (Battery Pack Management System). Among them, battery density, material, and temperature determine the speed of fast charging, and BMS is the core component that controls fast charging. When charging an electric vehicle, the battery management system BMS on the electric vehicle will estimate the state of charge (StateofCharge, the remaining battery power) of the power lithium battery pack, and automatically adjust the charging current according to the condition of the battery pack to ensure that the remaining battery power is maintained at Within a reasonable range, prevent damage to the battery due to overcharge or over-discharge.
5. How is battery life measured?
Battery life is a measurement of capacity. What is Battery Capacity? Battery capacity is a reference to the total amount of energy stored within a battery. Battery capacity is rated in Ampere-hours (AH), which is the product of:
AH= Current X Hours to Total Discharge.
Battery Capacity: mAh rating
an abbreviation for milliamp hours. Milliamp hours is a technical rating that defines the battery’s total capacity. The higher the mAh rating, the longer your battery can last between charges.
Battery capacity quanitifes the total amount of energy stored within a battery. More capacity equals longer time between battery charges. Battery capacity is measured in amperes, which is the volume of electrons passing through the batteries electrolyte per second. A milliAmp hour (mAh) is the most commonly used notation system for consumer electronic batteries. Note that 1000 mAh is the same as 1 Ah. (Just as 1000mm equals 1 meter).
