Why Is It Important To Have a Battery Management System?
A battery management system or BMS has become an inevitable part of every commercial activity. It monitors the state of lithium phosphate batteries and ensures the safety of business operations. As new technologies advance, more applications increasingly depend on batteries to maintain superior performance.
Even though lithium
phosphate batteries work phenomenally on their own, a battery management
system should support it to avoid any potential risk of overheating, mechanical
stress, over-voltage, etc.
What
is Battery Management System (BMS)?
The battery management system is a digital
hardware device integrated with specific software that ensures efficient usage
of batteries & eliminates safety risks.
Let’s
look at the primary functions of a battery management system:
Performance
optimization
Having a battery
management system can help optimize the performance of the lithium-ion
battery pack as industries use rechargeable batteries, so it becomes important
to monitor the pack of batteries constantly to avoid the risk of over-charging
& deep-charging. BMS controls charging & ensures that cell voltage
doesn’t reach too low.
Safety
Lithium phosphate
batteries have a high energy density making them more
prone to catch fire, and this is where the battery management system comes to the
rescue. BMS ensures everything operates in safe conditions by controlling the temperature
and voltage of the battery pack.
Health
monitoring
The battery management
system also keeps the health of the battery pack in check by collecting
all the data related to its state of charge & state of health. BMS provides
feedbacks like power & energy estimation to keep the maintenance technician
informed about any risky situation.
Communication
The battery management system is
responsible for communicating internally with other electronic units to control
the voltage output of the battery pack.
Cell
imbalance
Unlike lead-acid batteries, lithium phosphate batteries don’t self-equalize during
charging. If you stop charging when only one cell is fully charged while other
cells are not, the battery will perform below its ideal capacity.
Lithium phosphate batteries are connected with a battery management
system to ensure that the battery functions ideally and within safe limits. A
well-designed BMS has become more than just an option in today’s business
landscape of battery-powered applications.
