Lithium batteries are getting all the attention but for all the right reasons. These rechargeable batteries, so you won't have to replace them once they run out of energy. Lithium batteries are the best option for your renewable energy sources to store the energy in them.
For your solar panel system, a 48V lithium battery is surely a considerable option. Nowadays, you will find a lot of variety in lithium batteries with different price tags. Well, the prices depend on the energy storage capacity, but if we talk about 48v lithium batteries, both cheaper and more expensive options are available.
Prices Depend Upon the Storage Capacity
You can get a 48v lithium battery, but what would be the ah that you are looking for? Well, the price of the 48v lithium battery depends on the ah of the battery. If you get a 48v 30ah lithium battery, it won't cost you much. As you can get, it is between $466-$550. you also can have the option of customizing the battery pack according to your requirement.
Ah is the ampere-hours, and the amount of energy charged in the battery will allow 1 ampere of energy to current for an hour. So, you can get a 48b lithium battery with 100ah, but it will surely cost you a fortune because its price tag can be above $1000.
Again, the price depends on the type of lithium battery you are buying because they are available in a variety. Different lithium batteries have different price tags. For your solar system to work perfectly, you must get a 48v lithium battery with maximum ah to keep your system running for hours.
Type of Cell
48v lithium battery performs better than any other battery available in the market, depending on its. A 48v lithium battery consists of multiple cells that improve its power storage capacity. If we talk about a 48v lithium-ion battery consists of 16 cells in total, which are 3.2v lifepo4 cells.
The lifepo4 cells are those in which you will find lithium iron phosphate in the cathode material. The main reason people consider buying this battery is because its main purpose is to store energy.
Well, there is a possibility that you might get a 48v lithium-ion battery that consists of 15 cells, but all of them will be 3.2v lifepo4 cells.
All these cells together will give you a voltage of 51.2v. You can also get a customized 48v lithium-ion battery according to your requirements.
Well, in this case, the number of cells might increase according to your needs, and if the number of cells increases, the product's price will also increase. People who get solar systems for producing energy for their space consider the option of customized lithium-ion batteries that would be the perfect option for their solar system to work.
Requirements and Design of Lithium-ion Battery PCM
A lithium-ion battery has safety features that keep it cool down so it won't heat up. PCM is a protective circuit board that protects the cells from voltage fluctuation and current while the battery is charging or discharging. Without the PCM, your battery cells are unsafe, and the current fluctuation can cause damage to them. Therefore, the PCM keeps them safe so they don't die and keep working.
Enhanced Resistance Against High Temperature
You need PCM in your lithium-ion batteries to keep the cells inside the battery pack safe from voltage fluctuation but what about heat? What if your battery heats up due to any reason? Then, which cells won't get affected by it? The PCM you are designing for your lithium-ion battery must have a melting point below 40 degrees centigrade.
PCM keeps the cells cool down so a short circuit doesn't occur when a voltage fluctuation occurs. So you have to pay attention to the melting point of the material you use for designing your PCM. Otherwise, if the PCM material is not resistant to higher temperatures, then it will cause damage to your battery pack components.
PCM Made up of Graphite and Paraffin
PCM is an important battery pack component because it protects cells from voltage fluctuation. Otherwise, a short circuit might occur, and your battery might explode. The requirement for making a lithium-ion battery PCM must be made up of graphite and paraffin wax. These two materials offer better resistance against thermal management, and thermal runaway propagation happens in lithium-ion batteries.
Graphite and paraffin wax together will be the ultimate solution for this situation. So the material used for the PCB of your lithium-ion batteries is graphite and paraffin wax.
Requirements and Design of Lithium-ion Battery Shell
Once you are done designing the lithium-ion battery pack, it is time to work on the battery shell. Well, you have to be careful with this step because the safety of the internal unit of your lithium-ion battery depends on it.
Ni-coated Steel for the Shell
The shell of lithium-ion batteries must be made of steel and must be Ni-coated. As you know, external factors can damage the internal battery pack, but a Ni-coated shell will keep the internals of your battery pack safe from getting damaged.
Ni-coated steel shell keeps the lithium-ion batteries safe from any chemical reactions because chemicals won't be able to reach inside the battery. If you think the steel might get corroded, you are highly mistaken. The Ni coating will keep the steel in shape and safe from corrosion.
Ni-coated steel has great resistance against chemicals and corrosion, so the insides of your lithium-ion battery stay safe from any external damage.
Final Words
48V lithium batteries are expensive if you want to buy them with maximum energy storage capacity. Well, while buying a lithium battery, you must also know your requirements and the budget. Lithium batteries are surely durable and long-lasting. The more money you spend, the more benefits you will get; all lithium batteries have amazing features, but you must pay attention to the design and manufacturing details.
