BMS
The battery management system consists of a battery module management unit BMU, a battery cluster management unit BCMU, and current and temperature detection units. The BMS system has functions such as high-precision detection and reporting of analog signals, fault alarms, uploading and storage, battery protection, parameter settings, passive balancing, battery pack SOC calibration, and information exchange with other devices.
Cooling system
Battery container using air-cooled design, external industrial air-conditioning refrigeration heating system, through the container lithium battery thermal simulation effect of the container air duct design, to ensure that each way battery racks are able to meet the temperature balance, so that each group of battery racks of the upper and lower layers of the battery module temperature difference is controlled in the optimal operating temperature range.
Fire Protection System
Aerosol gas fire protection system with gas extinguishing control panel, detectors, manual alarm buttons, audible and visual alarms, alarm indicators.
20ft Container
C5 level, anticorrosion, with a certificate from the classification society, it can be transported by sea, Air cooling method conditioned.
Cables
DC side to AC side cables and AC and DC inside cables including Power cables, communication cables.
