They are the longest lasting batteries on the market as they have very low self-discharge, do not have excellent deep discharge response and memory effect, are completely discharged and are made of very light components. light battery. Various shapes. It also offers much better performance than traditional batteries. Its energy density is three times that of traditional batteries and it can withstand higher charge and discharge currents.
Another advantage of lithium batteries is the battery management system and uninterrupted self-powered operation in the event of a power outage.
What are their characteristics?
Knowing these features will help you select a solar array for the type of installation you are using.
- Capacity: The amount of current (amps) that is drawn when an electric battery is fully discharged when fully charged.
- Charge Efficiency: The proportion of energy used and stored to fill the battery. So the closer you are to 100%, the better.
- Self-discharge: This is the process of an electric battery that tends to discharge when not in use.
- Depth of Discharge: The amount of energy (%) obtained from a fully charged discharge.
The working principle of a photovoltaic battery is the redox reaction of the chemicals that make up the battery. One of these substances is oxidized and loses an electron, while the other substance gains an electron and is reduced.
The great advantage of a battery is that it can return to the original configuration if certain conditions are met. That is, it prevents the supply of electricity or the charging of oxidized components by completing the circuit and discharging at the same time.
Batteries contain chemical batteries with positive and negative electrodes, in addition to having electrolytes that allow the passage of electricity. In these cells a chemical reaction takes place and the chemical energy is converted into electrical energy.
