In recent years, as automotive battery suppliers have transformed towards electrification and intelligence, the global market size of stop start battery have continued to grow. In 2023, the global automotive lead-acid battery market was valued at US$13.3 billion and is expected to maintain a high growth rate in the next few years.
Stop and start battery, as an important technology
for energy saving and emission reduction in automobiles, has an
increasingly prominent market potential. Start-stop batteries can
provide power support when the car starts and stops, effectively
reducing fuel consumption and emissions. At present, automobile
start-stop batteries are mainly lead-acid batteries, which can be
divided into EFB battery and AGM battery. Start-stop battery can also be further subdivided into traditional batteries, maintenance-free batteries, etc.
Currently on the market about 70% of the newly listed vehicles are
equipped with start-stop technology; German cars Mercedes-Benz, BMW,
Audi full-system equipped with start-stop technology, the use of AGM start-stop car battery;
Japanese cars such as Mazda full-system (Atlas, Encore Sierra, cx4,
cx5), Toyota (HANLANDA, CROWN, Camry, Corolla Twin Engine, RAV4)
equipped with automatic start-stop, the use of more than the EFB start-stop car battery.
JYC Battery is
a company specializing in the manufacture and sale of lead-acid and
lithium batteries for various applications. The company has
manufacturing plants in China and Malaysia and exports its products to
more than 110 countries worldwide. Its product portfolio includes
start-stop automotive batteries, maintenance-free batteries, motorcycle
batteries, VRLA batteries, lithium batteries and energy storage systems. As one of the major global automotive battery suppliers, what kind of automotive batteries does it produce？
Working principle of start-stop battery
Ordinary car: After the engine is ignited, the car battery is always charging.
Start-stop car: When the car stops temporarily (such
as when waiting for a traffic light), the engine will automatically
shut down when the brake is stepped on deeply. At this moment, the
high-performance start-stop battery provides power for
all electrical devices in the car. When the brake is released or the
accelerator is stepped on, the start-stop battery is responsible for
high-power discharge to start the engine. When the start-stop battery is
working, the purpose of reducing automobile exhaust emissions is
achieved.
AGM start-stop car battery
AGM start-stop car battery refers to a battery with ultra-fine glass
wool material used for the partition. Its structure is different from
that of traditional lead-acid batteries. It is a lean battery with a
small amount of electrolyte and all of it is adsorbed in the glass
fiber. There is no flowing electrolyte inside the battery. It is
precisely because of this unique structure that the interior of the AGM battery is
more stable and the charging and discharging process is more balanced.
Compared with traditional batteries, its cycle charging capacity is 3
times higher and has a longer service life. It has higher capacity
stability throughout the entire service life (about five years) and is
more reliable at low temperatures. And because the electrolyte is 100%
sealed, there will be no gas leakage during the operation, which is
safer and less harmful to the environment. Even if a collision occurs,
there will be no acid leakage.
EFB start-stop car battery
EFB battery is a flooded enhanced start-stop battery, which is
developed on the basis of ordinary lead-acid batteries. It can be
regarded as an upgraded version of the traditional lead-acid battery.
Except for the solid components such as plates and baffles, the
remaining space is filled with electrolytes and can withstand high
temperatures. This is why it is called a “flooded battery.”
Compared with traditional maintenance-free batteries, EFB batteries
have been strengthened in many details so that they can repeatedly
release strong currents in a short time and can also stably endure
charging currents that are much larger than traditional batteries so
that they can become a start-stop battery.
MF maintenance-free car battery
MF maintenance-free car battery adopts an advanced valve sealing
design in structure, which makes the battery almost maintenance-free
during use. Compared with traditional lead-acid battery factory, MF maintenance-free battery manufacturers use
low antimony alloy or Pb-Ca alloy as the grid frame of the electrode
plate, which increases the overpotential of positive electrode oxygen
and negative electrode hydrogen evolution and reduces water loss, thus
ensuring that the battery does not need to be replenished during its
entire service life.
In terms of performance, MF maintenance-free car batteries have
excellent starting current, anti-overcharge ability and storage time.
These characteristics enable MF maintenance-free batteries to provide
stable and reliable power support during car starting, driving and
parking.
However, in order to extend the service life of the battery, car
owners still need to regularly check the color of the electrolyte in the
battery, keep the battery surface clean, and rinse with hot water in
time when solid oxides are found on the electrode. In addition, during
the use of the battery, car owners should avoid over-discharge and
long-term non-charging to ensure the performance and life of the
battery.
Truck battery
The truck battery, designed to meet the power needs
of the vehicle when it is stationary for a long time, is a
high-performance, long standby and easy-to-maintain energy storage
device. It can not only provide continuous power support for the
vehicle’s anti-theft system, remote start, car audio and navigation
system, but also power the vehicle’s starting system in an emergency to
ensure that the vehicle can start smoothly.
Marine battery
Marine batteries are high-performance energy storage devices designed
for marine and water navigation applications. They not only meet the
needs of stable and lasting power in daily ship operations but also
adapt to the unique challenges of the water environment, such as
humidity, vibration and changing load conditions.
Marine batteries have excellent waterproof and moisture-proof
performance. The outer shell is made of corrosion-resistant materials,
which can effectively resist seawater erosion and salt spray corrosion,
ensuring stable operation in severe weather and long-term offshore
operations. Its design also takes into account the space limitations of
the ship, providing a compact and lightweight structure for easy
installation and layout, while ensuring sufficient energy density to
meet the diverse power needs from small yachts to large cargo ships.
Motorcycle Battery
Maintenance-free motorcycle battery refers to
batteries that do not require maintenance or only require a small amount
of maintenance to function normally. Unlike open batteries, this
battery does not need to be replenished with liquid and water. The
electrolyte is immersed in the separator between the cathodes. Even if
the battery is tilted, the electrolyte will not flow out.
Maintenance-free motorcycle batteries are very suitable for
long-distance riding or applications in harsh environmental conditions
due to their excellent performance, long life, safety and reliability,
and simple maintenance.
Auxiliary battery
Auxiliary battery refers to a storage battery
specially used in automobiles. Its function is to supply power to the
starter, ignition system and other major electrical equipment when the
engine is started, and to supply power to various electrical equipment
when the engine is not running or running at a low speed. When there is
too much electrical equipment and the power consumption exceeds the
power supply capacity of the generator, the auxiliary battery can also
assist the generator in supplying power to various electrical equipment.
It is equivalent to a large capacitor, which can absorb instantaneous
overvoltage in the circuit, stabilize the voltage, and protect
electrical equipment.
