Lithium iron carbonate battery: Lithium iron carbonate battery is an old lithium battery technology with low charging efficiency, usually between 80-90%. The lithium iron carbonate battery needs to adopt a constant current charging method, that is, keep a constant charging current during the whole charging process until the battery voltage reaches the set value. Because of its low charging efficiency, long charging time and high charging electricity fee.
Lithium manganate battery: Lithium manganate battery belongs to intermediate lithium battery technology, and the charging efficiency is usually between 90-95%. Lithium manganate battery can be charged at constant current or constant voltage, and gradually reduce the charging current until the battery voltage reaches the set value, and then keep the charging voltage unchanged to continue charging. Lithium manganate battery has high charging efficiency and short charging time, so the charging electricity fee is relatively low.
Ternary lithium battery: Ternary lithium battery is an advanced lithium battery technology, and the charging efficiency is usually above 95%. The ternary lithium battery can adopt constant current charging mode or constant voltage charging mode, gradually reduce the charging current until the battery voltage reaches the set value, and then keep the charging voltage unchanged to continue charging. Ternary lithium battery has high charging efficiency and short charging time, so the charging electricity fee is relatively low.
To sum up, according to the charging efficiency and charging method, the charging electricity fee of ternary lithium batteries is usually lower than that of lithium iron carbonate batteries and lithium manganate batteries. However, the actual charging electricity fee is also affected by the local electricity price and the charging efficiency of charging equipment, and the specific situation needs to be calculated according to the actual situation.
