Containerized Battery Energy Storage System (CBESS) is an important
support for future power grid development, which can effectively
improve the stability, reliability, and power quality of the power
system. With the advantages of mature technology, high capacity,
high reliability, high flexibility, strong environmental
adaptability, scalability, and easy installation, it has a wide
application prospect in power systems. In consequence, as the
energy storage power source of the power system, the containerized
energy storage system is the development direction of energy
storage in the future.
Containerized energy storage system uses a lithium phosphate
battery as the energy carrier to charge and discharge through PCS,
realizing multiple energy exchanges with the power system and
connecting to multiple power supply modes, such as photovoltaic
array, wind energy, power grid, and other energy storage systems.
The battery energy storage system includes a lifepo4 battery pack,
lifepo4 BMS, energy conversion system, control system, and other
equipment. Among them, the core technology is the structure design
of the lifepo4 pack, the thermal design of the battery system, the
protection technology of the battery system, BMS, etc.
The shipping container solar system consists of a battery system
and an energy conversion system. Lithium-ion battery energy storage
systems contain advanced lithium iron phosphate battery modules,
BMS, and fuse switches as DC short circuit protection and circuit
isolation, all of which are centrally installed in the container.
In order to meet the capacity output requirements, several battery
modules are connected to form a lifepo4 battery pack. The DC output
of each lifepo4 battery pack in the battery system is connected to
the energy conversion system to convert DC to AC and AC to DC
(bidirectional), and control power as well. Solar battery storage
system conducts new energy access, grid-connected control, data
acquisition, remote transmission, unattended and other functions.
Compared with the traditional energy storage power station, it has
the characteristics of simple installation and debugging, beautiful
appearance, and so on, and is especially suitable for the
application requirements of on-grid or off-grid energy storage
systems in high altitude, cold areas, islands, deserts, and other
complex environments.
Containerized energy storage system is a 40-foot standard container
with two built-in 250 kW energy storage conversion systems. The 1
MWh lithium-ion battery storage system, BMS, energy storage
monitoring system, air conditioning system, fire protection system,
and power distribution system are centrally installed in a special
box to achieve highly integrated, large-capacity, and mobile energy
storage equipment. It has the characteristics of heat insulation,
constant temperature, fire retardant, wind and sand protection,
etc., which can meet the needs of various environments.
