Is the voltage of lithium battery packs the same?

　　In recent years, the development of new energy in China has been in full swing. Lithium battery technology has improved rapidly, but the price has fallen rapidly, which has a great impact on the original lead -acid battery mall. By calculating, the price of lithium batteries is not much different from lead -acid batteries and is convenient to use. It can charging at any time without damaging the battery, and the weight and volume are less than half. This has achieved many electric forklifts, electric carriers, golf cars, etc. Many batteries using lead -acid batteries have now turned to lithium batteries.

　　Lithium batteries have many advantages, but security and reliability are its disadvantages. Lithium battery is not simple. As a user, we need to be safe and reliable high -quality products. So how to choose power lithium batteries such as electric forklift lithium batteries?

　　To find high -quality products, first of all, we must understand the manufacturer's brand, planning, technical strength and concepts. Focusing on building a big brand, persistent products, focusing on word of mouth, huge planning, large development; D funding, and many years of work experience. These are the foundations of making excellent products. The product will not be too good. We can check the establishment time of a company, the work experience, technical strength, including patents and expertise, brand influence, planning, perhaps bad promise records, and so on. Suppose we understand these clauses one by one, then even if you buy online, there is a big time to buy good products.

　　Next, we investigate the two major components of electric forklift lithium batteries: battery cells and BMS (can be said to be a more messy protective board). The battery is the main body of lithium battery energy storage. It is the main body of the entire battery. Its quality is directly related to the quality of the battery pack. The requirements of electric forklift lithium batteries and electric sedan lithium batteries are very close. Choosing such power lithium batteries to become the best choice. Thanks to the rapid development of domestic new energy cars in recent years, the technology and safety of car power lithium batteries have developed rapidly, and the output has also improved significantly, providing sufficient sources for the battery supply of electric forklift lithium batteries. As long as the battery cells of the domestic first -tier brand cars lithium battery manufacturers are good, the quality is good. Assuming that battery manufacturers supply guarantee, you can use it safely. It is important that many bad businesses will use the combat method of unknown manufacturers, and even the battery may be recycled, and it is directly sold to consumers without passing the test. It is not guaranteed that such batteries are not guaranteed regardless of function, capacity, and safety. Everyone must polish.

　　In addition to batteries, BMS is a very important component. It includes base protection and some auxiliary functions. BMS has built a security barrier for lithium batteries through charging, discharge, short -circuit protection and other functions. Of course, BMS, which has good functions, is not low. In order to save capital, bad merchants saved this, which brought great hidden safety hazards to users. Although it is not necessarily a problem immediately, the problem is sooner or later. There is no trivial matter in front of the safety. This money cannot be saved. Try to choose a well -known brand BMS with good reputation. The simple way to distinguish whether the BMS is during it is a discharge survey. Assuming that the battery does not protect at the standard discharge intercept voltage, that is, the voltage mutation is zero, but gradually decreases, then there is no BMS on the foundation. Of course, we can also directly open the battery check whether there is BMS. Automatic balance function is the second most function of BMS demand. The forklift lithium battery is generally connected in series by multiple battery cells. The battery has a long time. Because of the consistency error and cumulative error between batteries, the battery will be added, resulting in a larger and larger voltage difference.

　　The capacity of the lithium battery of forklifts is generally above 150AH, and the traditional method of forced balance method does not play any effect. Assuming that BMS does not supply automatic equilibrium function, it may take half a year or one year, and the battery pack capacity will be much less, and the decline will be obvious. The cost of the active balance circuit now is very high, which is almost the same as the BMS capital, so many BMS will not be equipped with this function, which will affect the service life of the battery. The automatic equilibrium technology is balanced through energy. The foundation does not generate any heat, and the forced balance is to complete the voltage balance between the battery at the high voltage cell at the high voltage cell at the high voltage cell. A very obvious difference is whether there is a fever at work. We can use this method to determine whether it is automatic balance. Another simple recognition method is to see if your battery can be charged to the maximum extreme voltage after each charging. Suppose it is not possible, indicating that the battery is uneven, and the BMS does not have an automatic balance function. This method is suitable for battery for a period of time. Assuming that the start of the charging constraint cannot be reached, it means that there is a problem with the battery.
