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.
