The working principle of emergency lithium-ion energy storage vehicles or
megawatt level fixed energy storage stations is to directly convert high-power
lithium-ion battery packs into single-phase or three-phase AC power through
inverters. Normally, you only need to freely choose the charging period to
charge the battery pack. When the lithium-ion battery pack is fully charged, it
can be called up at any time. Energy storage batteries are indispensable
components for storing energy in solar photovoltaic power generation systems.
Their important function is to store the electrical energy of the photovoltaic
power generation system and provide power to the load during insufficient
sunlight, nighttime, and emergency situations.
1. Charging
Emergency lithium-ion energy storage vehicles or megawatt level fixed
energy storage stations are equipped with slow and fast charging ports. The fast
and slow charging method controls the length of charging time by selecting
different charging currents. The entire charging process is monitored by an
intelligent management system. When any individual voltage of the lithium-ion
battery reaches the set value, the charger will automatically terminate charging
the battery pack.
2. Discharge
Emergency energy storage vehicles or megawatt level fixed energy storage
power stations are specifically designed with output interfaces (usually
designed according to user requirements for high-power three-phase output
interfaces and conventional single-phase output sockets).
3. Maintenance
Normally, all you need to do is check the indicators of each individual
battery on the display screen of the lithium-ion battery management system,
without the need for manual maintenance. The battery management system is
equipped with known capacity display, voltage display, and display of the
temperature of each individual battery and its minimum or maximum voltage.
