Product introduction:

This Shenzhen SAIJIAOYANG ENERGY SCLENCE TECHNOLOGY Co,Ltd pack (including BMS)designed and manufactured by Shenzhen SAIJIAOYANG ENERGY SCLENCE   of 8S1P cells in series. The battery is assembled with intelligent sorting, which is accurate and reliable .The BMS uses a professional protection plate test system to conduct a comprehensive test before going online to ensure that the BMS achieves a comprehensive and effective protection for battery pack during the period of use. This product has the characteristics of high energy density, long life, safety and reliability, light weight, and wide temperature range

Function description:

Figure 1 Network position of LFP module in communication power system of 24V 100Ah Wall Mount.
The LFP module keeps the floating charge online when it is fully charged. When the power module output is abnormal (non-output overvoltage), it provides a DC backup function with zero transition time. The built-in battery management unit performs charge and discharge management of the battery pack and provides various of protection functions, at the same time, the module’s
operating status and alarm information are reported via the alarm indication interface RS485. The RTN (+) ground in Figure 1 is only for illustration. The positive and negative output ports of the external
battery pack of the 25.6V100AH LFP battery module must be completely isolated from the module’s metal case2

Critical performance test:

Note: Unless otherwise specified, the charge and discharge tests of the battery pack and cell are performed under the environment of temperature 20 ℃ ± 5 ℃, relative humidity 25% ~ 85%, and atmosphericpressure86Kpa ～ 106Kpa

Charging mode:

When the BMS detects that there is an external charging voltage ≥29.2V, and the cell voltage and temperature are both within the chargeable range, it will turn on the charging MOSFET for charging. When the charging current reaches the effective charging current, it enters the charging mode.
