AGV Lithium Battery Buying Guide
Why Choose Lithium Battery For AGV?
Lithium battery due to higher operating voltage, smaller size, lighter
weight, higher energy, lower self-discharge, longer cycle life no memory effect,
no pollution, is the ideal energy carrier in nowadays. Lithium battery which is
used in boat is not only a dependable power source, but it is also a green
choice for environment because it is composed of recycle materials.
Lithium batery is non-toxic and it will not emit any vapor or fumes. For
decades, deep-cycle submerged lead-acid batteries have been the most
cost-effective means of powering AGV. But with the rise of lithium batteries in
many high-power applications, many people are now studying the advantages of
lithium batteries. Generally speaking, AGV batteries are mainly divided into
lithium batteries and lead-acid batteries. If you’re looking for all the
benefits of battery, DNK lithium battery is your perfect choice.
What is AGV Battery Technology?
Automated Guided Vehicles (AGVs) are mobile robots that are used in various
industries for transportation and material handling tasks. AGVs are known for
their efficiency, accuracy and cost-effectiveness in performing these tasks.
However, AGVs require a reliable and long-lasting power source to operate
efficiently. This is where AGV battery technology comes into play.
AGV batteries come in various forms, including gel, lead-acid and lithium-ion
batteries. However, the best type of AGV battery technology depends on the
battery charging strategy of the AGV. In recent years, lithium-ion batteries
have become increasingly popular for AGVs due to their high performance, long
life and charge cycles.
Lithium-ion batteries are a type of rechargeable battery that use lithium
ions to store energy. These batteries are known for their high energy density,
which means they can store more energy in a smaller and lighter package compared
to other battery types. This is particularly important for AGVs, as they require
a battery that is lightweight and compact to ensure maximum mobility and
efficiency.
Lithium ion battery for AGV is designed to meet the specific requirements of
industrial trucks and mobile robots. These batteries must be able to withstand
high discharge rates, frequent charging cycles, and extreme temperatures. They
must also have a long service life to minimize the need for frequent
replacement, which can be costly and time-consuming.
AGV lithium-ion batteries are available in different chemistries, such as
Lithium Iron Phosphate (LiFePO4) and Lithium Nickel Manganese Cobalt Oxide
(LiNiMnCoO2 or NMC). LiFePO4 batteries are known for their high safety and
stability, while NMC batteries offer high energy density, light weight, and
small size.
The best AGV battery technology depends on the specific requirements of the
AGV and its battery charging strategy. Lithium-ion batteries, particularly
LiFePO4 and NMC chemistries, are becoming increasingly popular due to their high
performance, long life and charge cycles, and ability to withstand extreme
conditions. Choosing the right AGV lithium-ion battery is crucial to ensure
maximum efficiency and cost-effectiveness for AGV operations.

Factors to consider when choosing an AGV battery
AGV lithium-ion batteries are increasingly popular in markets and stores, so
you must know the basic indicators of a great battery before choosing.
High stability
When purchasing an AGV battery, be sure to know the type of material and the
shell strength of the battery. AGV batteries that are made of Lithium-ion
phosphate are considered to be very stable and reliable.
Furthermore, Lithium-ion phosphate A-grade batteries have the lowest
self-discharge rate of any battery. This means that you don’t have to worry
about the high frequency of charging due to the rapid self-discharge of the
battery.
AGV lithium-ion phosphate batteries also have a high energy density and
voltage capacity, enough to power your AGVs effectively without voltage
fluctuations or disruption in energy flow.
Battery charging
It is a vital factor to consider when selecting any type of battery, but it
is especially significant for AGVs since it influences the overall performance
of the AGV in the long run.
There are two types of AGV battery charging systems: battery swapping and
battery charger.
In the Battery Swap, a dead battery is replaced with a fully charged one.
After replacement, the removed battery would be recharged for later use.
Battery chargers are either built-in or external chargers that use external
power sources to recharge the AGV battery. They are very convenient to use and
increase battery stability and reliability.
You can carry out this charging system either by plugging it into a charger
or by wireless induction. It just takes a long time to wait. However, charging
will be more convenient in the battery swap system. This swapping system can
save the charging time and help improve work efficiency.
Intelligent control
AGV batteries need to be monitored to prevent unplanned breakdowns of the
vehicle while in use. So, manufacturers of AGV batteries have included several
intelligent control features that allow you to monitor the status of your
battery.
Intelligent control measures, such as Bluetooth, GPS, Radio-frequency
identification, Cloud connectivity, etc., have been developed to ensure
connectivity between your device and the AGV battery to monitor its performance.
When choosing your ideal AGV battery, it would help if you considered this
factor.
Safety
The best AGV battery should be risk-free to operate. This crucial aspect has
prompted manufacturers of AGV batteries to incorporate several safety
precautions. The Battery Management System (BMS) is a significant safety control
device present in AGV batteries.
It’s important to take good care of your battery to avoid overheating,
overcharging, and battery discharge. That’s why the BMS is designed to keep a
close eye on the battery’s charging, voltage, temperature, and current. This
helps keep your battery safe and healthy for use on AGV because the BMS ensures
that the battery is in excellent condition while in operation.
Advantages of Lithium batteries for the AGV industry compared with other
batteries
Lithium battery has a high energy density. Compared with a high-capacity
nickel-cadmium battery, the volumetric energy is 1.5 times and the energy
density is twice. High voltage, the average use voltage is 3.6V, which is three
times that of nickel-cadmium batteries and nickel-hydrogen batteries. The use
voltage is flat and high-capacity, and the wide use temperature is -20℃-60℃. The
charge and discharge life is long, and its capacity is at least 70% after 500
discharges. Lithium batteries have the characteristics of high energy density,
high voltage, and stable operation.
What kind of battery is used in AGV?
Depending on the application and environment, you can use different types of
batteries for your AGV. Some of the common AGV battery types are:
Lead-acid battery
An AGV lead-acid battery is a specific type of battery that mainly consists
of lead and sulfuric acid. It is one of the oldest and most used battery types
in AGVs and other industrial vehicles. AGV lead-acid batteries may be divided
into two basic groups: flooded and sealed.
In contrast to sealed lead-acid batteries, which contain the electrolyte in
the form of a gel or an absorbent glass mat (AGM), flooded lead-acid batteries
have liquid electrolytes. Batteries like GEL and AGM Pure-Lead are examples of
sealed lead-acid batteries.
Lithium battery
This type of battery employs lithium ions as its leading charge carrier,
making it the most refined and well-liked option for AGVs at this stage. In
terms of energy density, battery performance, longevity, and recharge time, this
battery is better and exceeds other battery types, including lead-acid
batteries.
Additionally, they are maintenance-free, spill-proof, and appropriate for
online and quick charging. Thanks to their online charging, these batteries are
the ideal option for electrostatic AGVs with a high-efficiency rate and no cable
connection.
AGV lithium batteries are able to provide more power and run for longer
periods with less weight and space because they store more energy per unit of
weight and volume. Lithium titanate (LTO) and lithium iron phosphate (LFP)
batteries, both are very popular AGV lithium batteries.
