Products Description

LiFePO4 Lithium Battery

This product utilises lithium iron phosphate batteries with a cell capacity of 280Ah. The nominal cell voltage is 3.2V, with an operating voltage range of 2.5V to 3.65V per cell. The monthly self-discharge rate does not exceed 3%. These cells offer extended longevity, robust battery safety, and excellent consistency. The battery has passed multiple stringent national testing protocols, with safety performance meeting national standards.

HV Box

The high-voltage box features an integrated, compact design with optimised dimensions. It incorporates multiple interfaces for strategy expansion, including fire alarm, air conditioning, temperature detection, dry contacts, and RS485. Utilising DC-side power extraction eliminates the need for external power supply, enabling full black start capability for the system.

Monitoring Cloud Platform

The cloud platform supports direct wireless transmission of battery-side parameter information via 4G/WiFi/Bluetooth to the energy storage cloud platform, eliminating the need for an EMS system configuration. It further enables core functionalities including real-time battery system information and status queries, remote alarms, software/hardware traceability, as well as over-the-air BMS firmware upgrades and parameter calibration.
