Lithium-ion battery system features

A plurality of air-cooling devices are arranged in the battery compartment, so that the cooling air is blown along the maintenance channel through the main cooling surface of each battery module to ensure system temperature uniformity

nstall relays and fuses. When the battery system is turned off, the battery pack can be disassembled, so that the entire battery pack has no high-voltage output, which increases the safety of the battery system.


The battery modules are installed in series in the battery cabinet, and the battery cabinet is connected to the grid through a bidirectional DC module, which can perform bidirectional control of discharge and charging. The BMS provides real-time monitoring of battery status and secure management and protection of the battery system.

Energy storage power station

The energy storage power station consists of three parts :

  • Energy Management System (EMS)
  • Two-way energy storage converter (PCS)
  • Energy storage battery unit (battery and BMS)


Energy storage power station classification:

  • Containerized energy storage power station
  • Indoor energy storage power station


The main role of energy storage projects:

  • Intermittent power generation photovoltaic power station
  • Wind field
  • Outdoor temporary large load center, large non-stop factory or key enterprise plant


Container energy storage system

The Container Energy Storage System (CESS) is an integrated energy storage system developed for the needs of the mobile energy storage market. It can integrate energy storage converters and energy management systems according to customer requirements. The container energy storage system has simplified infrastructure construction costs. It is suitable for power stations such as firepower, wind energy, solar energy, or islands, communities, schools, scientific research institutions, factories, large load centers and other applications.
