Electronic Protection
Protection electronics are employed outside the cell(s)
to protect from overcharge, undercharge, and external
temperatures. Circuit protection solutions for battery
packs comprise several devices, which are crucial design
considerations during the charging and discharging of the
battery pack.
Two prevalent overvoltage and overcurrent protection
methods in cell designs utilize battery management
Integrated Circuits (ICs) and Field-Effect Transistors
(FETs). Most battery packs, battery cells, and specifically
single-cell Li-ion battery pack designs will need a second
level of protection. Bourns® Multifuse® Polymer PTC
(PPTC) devices or the company's miniature resettable
TCO devices, also known as mini-breakers, are optimal
overtemperature protection solutions. Also, dual battery
management ICs and FETs provide a two-fold level of
overvoltage and overcurrent protection. The protection
design can include a Current Sense Resistor (CSR) to
monitor the voltage/current.
Enhanced battery performance management that relies
on tight and low Temperature Coefficient of Resistance
(TCR) can be achieved with current sense resistors to
measure drift and resistance accurately. Bourns has a
comprehensive line of current sense resistors such as the
Bourns® CRM2512 Chip Resistors. These are high-power
current sense chip resistors with thick film technology.
These chip resistors are available with a rating of 2W in
a standard 2512 chip format. The CRM2512 with a wide
resistance range is suitable in power-supply circuits,
including current sensing and current limiting.
Conclusion
Well, as I come to the end of this, I need to take action and
recharge my batteries. I am off to recharge my laptop and
mobile to full power. Bourns is always providing products
to protect rechargeable batteries, ensuring a greener,
long-lasting solution for untethered power, convenience,
dependability, and mobility to make it to the end. Now, it's
time for me to unplug and recharge my brain cells before
heading home and fighting rush-hour traffic. ■
