BMS is the abbreviation of battery management system, as the name suggests, this is a kind of electronic system that can monitor and protect the rechargeable battery, BMS is an indispensable part of the rechargeable battery, and has an irreplaceable role in improving the safety of rechargeable batteries, the following is how to choose the right BMS for your lithium iron phosphate battery need to pay attention to aspects
First of all, to ensure that your lithium iron phosphate battery and BMS compatible, you need to understand the voltage range of your battery, the capacity of the battery pack and the battery maximum charging and discharging current and other basic parameters, because the BMS needs to be adapted according to the specifications of the battery in order to play a role, so that the basic parameters of the battery and the BMS compatible with the BMS is the first thing to consider when you choose the BMS.
As a simple example, in order to ensure that the BMS can function properly, you need to ensure that the rated voltage of your Li-FePO4 battery is within the BMS support voltage, and the maximum charge/discharge current of the Li-FePO4 battery should also be within the acceptable range of the BMS.
Before you buy the right BMS, you must understand the various functions of the BMS, which is the key data to determine whether the BMS is worth buying, generally speaking, the BMS mainly includes the functions of voltage monitoring, temperature monitoring and battery balance management, which are very important for the protection of your LiFePO4 battery.
As an example, the battery balance management function is one of the main functions of the BMS, this function can ensure that each lithium iron phosphate battery in your battery pack can be charged and discharged uniformly, so that the whole presents a balanced state, this is both for individual lithium iron phosphate battery or the whole battery pack, can greatly reduce the performance of the degree of degradation, to prolong its service life.
The safety of BMS is definitely one of the issues you need to consider, an excellent BMS can react to abnormal phenomena in the battery system in time, such as over-voltage, under-voltage, over-current, short-circuit, etc., and then make adjustments according to these abnormalities immediately to protect the whole battery system, which is very important for you.
For example, suppose your battery system is short-circuited due to external forces, if the BMS cannot cut off the operation of your battery system in time, it will cause your LiFePO4 battery to overheat, which will lead to the damage of the battery or even fire, so it can be seen that the safety of the BMS is very important.
It can be seen that in order to protect the service life of your lithium iron phosphate battery, you must carry out certain tests on the fault monitoring and protection function of the BMS to ensure the reliability of the BMS, which to a certain extent can also protect your life and property safety.
Generally, BMS has a communication interface with the outside, which is to convey the battery status to you, so that you can make corresponding measures for the battery status, and this communication interface is subject to the constraints of the communication protocol, so before you buy BMS, the communication protocol of the BMS is an issue that you must consider.
You can ask the dealer about the communication protocol between the BMS you choose and the battery, i.e., whether the BMS supports CAN bus, 12C and SPI, etc. This is related to the efficient and stable operation of the whole battery system, so you must consider this issue before choosing a suitable BMS.
Choosing a well-qualified BMS can add a guarantee for the quality of BMS. At present, the certifications and standards for BMS in the industry mainly include IEC (International Electrotechnical Standard Certification), UL (Global Testing and Certification), etc., which ensure that the BMS meets the relevant international certifications, and are indispensable for BMS products.
So when you buy BMS, you can ask the businessman, or through the BMS product packaging whether there are these certifications and standards, to determine the correctness of the BMS before you consider whether to buy this BMS, which is very important, it is related to the future use of the BMS you buy experience and safety issues.
Many consumers who have purchased BMS products have made some comments on the performance of the product after using it. These comments can be the basis for guiding your purchase of a BMS, because they are the real feelings of those consumers who have used the BMS product.
It is not difficult to find these reviews, generally online BMS product purchase channels in the comments section you can find those BMS product reviews, of course, you need to appropriate screening of these reviews, and then for comprehensive consideration.
There are many famous BMS brands in the world, for example, Tesla’s BMS has a certain influence in the world, and its main production is automotive BMS, Tesla’s BMS adopts the master-slave architecture design, which means that it has a master board and multiple slave boards, and this kind of design structure can effectively guarantee the performance and safety of your Li-FePO4 battery.
Ricardo Plc is a British company that produces BMS, which enjoys a high reputation in Europe. The cloud connectivity technology developed by the company enables data capture and remote update of battery status, which is a good indication of the strong performance of Ricardo Plc’s BMS, and it may be a good choice for you.
In Asia, Ningde Times CATL’s BMS is recommended. The BMS of Ningde Times CATL can realize precise control and management of the battery through SOC, and this kind of monitoring is uninterrupted, which can effectively reduce the probability of abnormal situation of the battery, so it can be seen that the BMS of Ningde Times CATL has the leading level in the industry, and it is a BMS brand worth recommending.
If you buy BMS through offline channel, basically there are distributors of famous BMS brands in every region, you can consult with those distributors about BMS and they will answer your questions, of course, you can also get the quotation of BMS from the distributors, and you can choose and buy it according to your situation.
If you go online, you can save a lot of time, platforms like Alibaba and Amazon can provide you with BMS products, you can easily get the detailed information and specific price of BMS products from these platforms, and then you can buy according to your own needs.
Through the in-depth understanding of how to choose your lithium iron phosphate battery BMS related content, you can according to their own needs to pick the right BMS, I believe that with the existence of the BMS, your lithium iron phosphate battery can work better for you, if you have this idea, then you can take action quickly.
