BYD's independent electronic control IC + lithium battery PACK series
products
BYD is the world's largest manufacturer of nickel (alkaline) rechargeable
batteries and has very good capabilities in product research and development and
technical reserves. The products launched by BYD have a series of advantages
such as high performance, safety and reliability, low power consumption, fast
charging, high rate discharge, wide temperature range and long service life.
BYD's nickel battery can achieve more than 500 charge and discharge cycles.
It has low internal resistance, high voltage output discharge characteristics
under high current discharge, long storage period, and can be quickly charged as
needed. The fastest charging time is 15 minutes, which can be adapted to
large-scale applications. Range temperature, can also be used under conditions
of -20℃～70℃.
The company's nickel batteries are distinguished by capacity, ranging from
100mAh to 15,000mAh. There are four categories commonly used: standard type,
consumer type, high temperature type and high current discharge type, which can
be applied to any wireless device.
BYD established the 18650 lithium battery PACK project and cooperated with
outstanding battery cell manufacturers in the industry. Combining its own
electronic components, IC, SMT, Pack design and processing advantages, it can
tailor-made higher-quality and reliable products for end customers.
In terms of electronic control design, BYD provides the BM3451/3452 series
IC independently developed by BYD, both of which have the characteristics of
high precision and high integration. By monitoring the voltage, charge and
discharge current, and ring temperature of each battery, protection functions
such as battery overcharge, over-discharge, over-current, and temperature
protection can be realized. Overcharge, over-discharge, and over-current
protection delays can be adjusted through external capacitors. hour. In
addition, the BM3451/3452 series can be used in a variety of packaging forms to
provide customers with customized chip sizes.
BYD provides a variety of lithium batteries and new energy products, mainly
including LP series prismatic batteries, SL series polymer batteries,
LC1865/LC1865H series cylindrical batteries, and power modular battery packs

Wanxiang A123 (iron phosphate) power lithium battery and power source
module
A123 Company, a subsidiary of Wanxiang Group, is an American company
dedicated to the professional development and production of lithium-ion
batteries and energy storage systems. Its lithium-ion batteries are ahead of
lithium-ion batteries with long life, high energy density, high power and
excellent safety. battery market. The A123 lithium battery product uses lithium
iron phosphate as the battery cathode material. It is manufactured into uniform
nanoscale (0.0002 micron) ultra-small particles (currently general lithium
battery cathode material particles are about 100 times larger than lithium iron
phosphate particles), thereby significantly By increasing the discharge power of
the battery, the A123 lithium iron phosphate battery can release electrical
pulses 10 times faster than conventional lithium batteries, without affecting
the overall stability and cycle life of the battery.
A123 Company mainly provides lithium iron phosphate cathode materials. It
also focuses on the power lithium battery market and regards automotive lithium
batteries as its key development direction. A123 lithium-ion products
simultaneously solve the three problems affecting power lithium batteries in
terms of high power, safety and long life.
In terms of high power, A123 Company has tested that in the battery pack
developed for plug-in hybrid power, when the depth of discharge reaches 100%,
the battery pack can still maintain 90% of its capacity after 3,000 cycles. In
addition to providing high discharge, the lithium iron phosphate battery can
also provide bursts of energy. A123 has cooperated with KillaCycle, the world's
fastest electric motorcycle manufacturer, to use a battery module using 990 A123
battery cells (equivalent to 350 horsepower) to set a world record of 257
kilometers per hour and 0-97 kilometers acceleration in 1.5 seconds.
The A123 lithium battery can be used continuously for more than 15 years
based on daily charging and discharging, which is even longer than the life of
an average car. It is understood that the A123 lithium-ion battery cathode
material uses a method of adding an appropriate amount of carbon to iron
phosphate with very small particle size, thereby improving the battery's charge
and discharge cycle life characteristics.
In terms of safety, a set of batteries (capacity 16kwh) designed by A123
for the General Motors Volt electric vehicle can still work normally after the
crushing and destruction test. Other power lithium batteries will overheat and
catch fire if they are subjected to such high-speed impact.
At the same time, hybrid vehicles using A123 lithium batteries can further
reduce the gasoline demand of most car owners. The demand for gas fuel can be
reduced by 70%, and carbon emissions can be reduced by 50%. While reducing fuel
consumption, it is also harmful to the environment. The impact is reduced to a
minimum.
At present, A123 Company mainly provides AMP20/AHP14 square batteries,
APR18650/ANR26650 cylindrical batteries (cells), AMP20 power source modules, 12V
starter batteries/48V battery packs, etc.
