Good safety feature of LFP batteries makes LFP a good potential replacement for lead-acid batteries in many applications. The LFP charging systems are adapted not to damage the LFP cells through excessive charging voltages, temperature-based voltage compensation, equalization attempts or continuous trickle charging. The LFP cells are normally balanced before the pack is assembled and a battery management system also needs to be implemented to ensure fine protection over the cells.
Thanks to the diversified sizes and dimensions of LFP battery cells, we are enabled to build up a complete set of battery packs with working voltage range from 12V up to 600V and power capacity from 6Ah to 1MWh. The battery management system inside the battery packs monitor the working condition of every battery cell series and parallels. It also provides timely protections agaist over-charge, over-discharge, overheat, massive current, etc. We will design corresponding BMS upon customers' requirement on the working status of the battery system. Please do not hesitate to contact us if you are in need of electric power for automotive or energy storage solution. We will provide you with a great variety of customized services.
LiFePO4 battery, or LFP battery, the full name is the lithium iron phosphate battery, which belongs to one kind of rechargeable lithium batteries, battery takes LiFePO4 as cathode materials.
For original LiFePO4 have low electric conductivity, many battery manufacturers make efforts on improving original LiFePO4 materials, like nano-technology, metal-doping, carbon-coating etc. Bestgo-Power takes metal-doping and carbon-coating to update original LiFePO4 materials for battery manufacturing.
The Amp-hour (Ah) is used for describing how much energy that battery can store in. The volume of the constant current (in amps) multiple with time (in hours) then got Amp-hour (AH) as battery capacity. For example, if a Forzatec LiFePO4 cell, marked as "10AH @ 3C discharge, 25°C", it means in 25°C condition, if discharge this battery with current no more than 30A (10AH, 3C), this battery can offer 10AH energy, like 30A current for 1/3 hour, or 5A current for 2 hours.
SOC, short for the State of Charge, is used to describe how full a battery is. When a battery is fully charged, we can say that the SOC of this battery is 100%. SOC can be used to describe how fully the lead acid battery charged, cause lead acid battery always need to be fully charged for storage. Later nickel batteries and lithium batteries also take SOC to describe energy reserve. Here is a formula describing the relationship of SOC and DOD, that is "SOC = 100% - DOD".
DOD, short for the Depth of Discharge, is used to describe how deeply the battery is discharged. If we say a battery is 100% fully charged, it means the DOD of this battery is 0%, If we say the battery have delivered 30% of its energy, here are 70% energy reserved, we say the DOD of this battery is 30%. And if a battery is 100% empty, the DOD of this battery is 100%. DOD always can be treated as how much energy that the battery delivered. For lithium batteries we do not suggest fully discharge them to 100% DOD, it would shorten the cycle life of batteries.
The self-discharge rate is a measure of how much batteries discharge on their own. The Self-Discharge rate is governed by the construction of the battery and the metallurgy of the lead used inside. Different types of batteries have different self-discharge rate.
Constant current / constant voltage (CC/CV) charging mode is a effective way to charge lithium batteries. When a Lithium Battery is nearly empty, we take constant current to charge it. We need to make sure that charging current should be lower than the max charging current that battery can accepted. With constant charing the voltage of battery is slowly upping, when battery volt reaches the max charging voltage, charger would make sure charging voltage fixed as "constant voltage" and reduce the charging current. When battery is fully charged this state would be stopped.
Battery cycle life is defined as the number of complete charge - discharge cycles a battery can perform before its nominal capacity falls below 80% of its initial rated capacity. Different types of batteries have different cycle life, LiFePO4 batteries life time of 2000cycles are typical.
Signal cell (battery) is an independent unit which contains a complete chemical reaction environmen
t inside. For nominal usage we need to make sure that cells / batteries are under specified conditions that data-sheet described. For lithium batteries, we suggest to take consideration of working temperature, and do not fully charged to 100% SOC and do not fully discharged to 100% DOD when using, by this way the cycle times of LiFePO4 could be effectively extended.
