Why Lithium-Iron Phosphate(LiFePO4 or LFP)?
Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the
mainstream li-ion battery types.Lithium batteries offer many
benefits over other battery chemistries. They are a safe and
reliable battery solution, with no fear of thermal runaway and/or
catastrophic meltdown, which is a significant possibility from
other lithium battery types. These batteries offer extremely long
cycle life,with some manufacturers even warranting batteries for up
to 10,000 cycles. With high discharge and recharge rates upwards of
C/2 continuous and a round-trip efficiency of up to 98%, it's no
wonder these batteries are gaining traction within the
industry.Lithium Iron Phosphate (LiFePO4) is a perfect energy
storage solution.What is the Battery Management System (BMS) and the way will it
work ?
BMS Protection options :
● Low Voltage Protection Switch – mechanically disconnects at
ten.0V
● Over Voltage Protection Switch – mechanically disconnects at
fourteen.8V
● Short Circuit Protection Switch – mechanically and safely
disconnects battery
● Reverse Polarity Protection Switch – mechanically and safely
disconnects battery
● Over temperature – mechanically shut-down battery till
traditional temperature recovery
Balancing options :
● Internal cell reconciliation – mechanically balances BLS® cells
throughout battery operation. reconciliation
algorithmic rule has been developed to confirm excellent balance
between cells throughout battery life.
● Charge reconciliation – for BLS® connected in parallel and/or
nonparallel, the BMS can balance every BLS® severally, so as to
produce a perpetually balanced battery system.
I Must Use The Battery Management System (BMS)?
Important facts:An LFP cell will fail if the voltage over the cell
falls to less than 2.5V (note: recovery by charging with a low
current, less than 0.1C, is sometimes possible).An LFP cell will
fail if the voltage over the cell increases to more than 4.2V.
Lead-acid batteries will eventually also be damaged when discharged
too deeply or overcharged, but not immediately. A lead-acid battery
will recover from total discharge even after it has been left in a
discharged state during days or weeks (depending on battery type
and brand).
The cells of an LFP battery do not auto-balance at the end of the
charge cycle. The cells in a battery are not 100%
identical.Therefore, when cycled, some cells will be fully charged
or discharged earlier than others. The differences will increase if
the cells are not balanced/equalized from time to time. In a
lead-acid battery a small current will continue to flow even after
one or more cells are fully charged (the main effect of this
current is decomposition of water into hydrogen and oxygen). This
current helps to fully charge other cells that are lagging behind,
thus equalizing the charge state of all cells. The current through
an LFP cell, however, when fully charged, is nearly zero, and
lagging cells will therefore not be fully charged. Over time the
differences between cells may become so extreme that, even though
the overall battery voltage is within limits, some cells will fail
due to over- or under-voltage. Cell balancing is therefore highly
recommended.
In Addition To Cell Balancing, A BMS Will:
* Prevent cell under voltage by timely disconnecting the load.
* Prevent cell overvoltage by reducing charge current or stopping
the charging process.
* Shut down the system in case of over temperature.
* A BMS is, therefore, indispensable to prevent damage to large
Li-ion battery banks.
Are Lithium batteries safe?
The Lithium Iron Phosphate (LiFePO4) batteries are the safest type
of Lithium batteries as they will not overheat, and even if
punctured they will not catch on fire. The cathode material in
LiFePO4 batteries is not hazardous, and so poses no negative health
hazards or environmental hazards. Due to the oxygen being bonded
tightly to the molecule, there is no danger of the battery erupting
into flames like there is with Lithium-Ion. The chemistry is so
stable that LiFePO4 batteries will accept a charge from a Lead-
Acid configured charger.
What is the life expectancy of a Lithium battery?
The typical estimated life of the Lithium Iron Phosphate (LiFePO4)
battery is 5-15 years, or 2000 to 8000 charge cycles. One charge
cycle is a period of use from fully charged, to fully discharged,
and fully recharged again.
If I want to solar charge LiFePO4/Lithium Ion battery, which
already has PCB, would a normal SLA controller work fine?
For LiFePO4 / Lithium Ion battery, we always recommend to use
LiFePO4/Lithium Ion solar controller. Especially if you are using
the battery as UPS (back up power supply). The Lead Acid solar
controller will constantly provide pulse current to the battery, in
the long run, it might damage the PCB. So the PCB won't be able to
protect the battery when it should be.
The LiFePO4 / Lithium Ion solar controller won't provide constant
current when the battery is fully charged. So it is much safer and
reliable.
I have a lead acid charger with high charging current; can I use it
instead to charge LiFePO4 batteries?
Lead acid batteries charge at 2.30V to 2.45V per cell whereas
LiFePO4 batteries require 3.65V per cell. Your battery would
potentially be undercharged, so you will not get use of the full
capacity of the LiFePO4 battery, nor will balancing be triggered in
the LiFePO4 battery pack, both of which are not desired.
Furthermore, the floating charge of the lead acid charger is not
expected by the battery and can cause problems. We recommend
purchasing the battery with the bundled charger.
