Have you ever wondered why consider battery protection? Don't worry; this comprehensive guide will tell you everything that you should know about battery protection!
Many people wonder – is my battery protected? If you’re in the place, then it means that you too have this concern. To know whether your battery is protected or not, you need to first know about the components of protected batteries.
A small electrical circuit is built into the cell packaging of the protected Lithium-Ion ( Li-ion) batteries. The protected battery ensures safety against typical dangers, including overcharge, discharge, short circuit/current, and temperature. Protected batteries in your gadgets are safer to use. These batteries are less likely to explode and rarely cause injury to individuals or objects.
These are the major components of protected batteries:
?PTC: Protect from overheating indirectly overcurrent as well. It automatically gets reset.
?CID or Pressure Valve: If the pressure gets too high in the cell, it will permanently disable the cell. (Can be due to overcharge).
?PCB: Depending upon nature, it protects against over-discharge, overcharges, and over current. The PCB is reset automatically or when it is put into the battery.
Not every battery is protected. And unprotected cells will damage if discharged extreme. To know if a battery is protected or not, continue reading.
Not all batteries you buy from the market are protected, as mentioned above also. Here are a few ways to see if a battery has protection:
The unprotected battery is flat, but the protected battery has a rim at its bottom and is very easy to see.
Unprotected batteries often have a magnetic bottom while a protected battery has a circuit board underneath, identical in color to the metal but is not magnetic.
The wrap is smooth in the unprotected batteries. Still, a protected battery is much softer and includes a front-back connection.
Unprotect flat top batteries are shorter than the protected batteries as the protected batteries take up some space, making them longer.
Usually, the unprotected battery grove can be seen at the top. Still, the grove is missing on the protected battery, but there is a rim at the bottom.
You go to work, and one morning you figure out that the battery system isn't running. What's happening? How much time are you going to waste trying to repair that? It is possible that having it back online would cost money, but how much?
That is not quite the worst-case scenario when it comes to battery malfunctions. What if, further downstream, disruption to the battery device causes equipment failure or even generates a fire?
Whenever you incorporate a new piece of equipment or create a new work procedure, you expect eventualities like this, so it's essential to know all the advantages before implementing your battery system!!
Let's take a look at the safety of circuits and why protected batteries are so important.
In order to really understand why battery protection systems are so critical, you need to know what can happen if they are not in place:
?Short Circuits
These happen when a shortcut is taken by a current. Electricity always needs to go down to the ground as quickly as possible. Still, it is kept on the right track by a correctly operating circuit. If the wire breaks in the chain, the current will escape and go in a different direction back to the ground. Which might involve going through your equipment or one of your employees.
?Overcharge
The additional energy becomes heat when you bring too much charge into a rechargeable battery. The battery temperature will climb above reasonable limits and decrease the longevity of the device.
?Over-Discharge
Draining too much of the battery charge can damage the battery in numerous ways, including decreasing the battery power, which makes charging more important, causing a short circuit within the battery. Without a safety mechanism for a lithium-ion battery, it would be very likely to over-discharge these and other malfunctions.
?Overcurrent
A variety of malfunctions, including short circuits, may generate too much current in the circuit. It may ignite components of the machines and trigger a fire if there is ample excess current.
So, how do battery protection systems help? The temperature and voltage in your battery are balanced with battery safety systems. Continuous temperatures are important to optimize battery life, which improves operational protection and reduces the costs of your material.
An efficient battery protection device will monitor the battery current and temperature by changing the circuit to protect you if the levels are unsafe. Some of the effective options are:
1) Polymeric Positive Temperature Coefficients
The polymeric positive temperature coefficient or PPTC, allows the circuit to control the energy excess. It opens up to high resistance, much like a normal fuse, when the device has too much current. When the current is down to normal, it is reset.
Unlike other fuser types, the PPTC resets so that, after correcting the overcurrent, you can still use the battery. It only keeps the battery functional until power returns to normal levels.
2) Protection Circuit Modules
Protection circuit modules, or PCMs, protect against overload, over-discharge, and overly rapid discharge. It keeps the battery running while helping to prevent damage while maintaining short and long-term battery life.
The Final Takeaway
People must consider whether they choose protected cells that are safer to run or accept greater liability and risk associated with unprotected cells. Many experts in batteries would recommend that you should use protected batteries.
What you are waiting for. Go and grab the protected battery to make your device long-lasting and ensure the environment is hazard-free!
