Lithium iron phosphate battery
Scope of application
This product specification describes the performance indicators of
lithium iron phosphate energy storage system produced by SHENZHEN
CONSNANT TECHNOLOGY CO., Ltd. (CONSNANT). This specification
product system is used for backup power supply in the household
small energy storage system or UPS backup power system. The DC
output voltage range is 10V-14.6V, and the capacity configuration
range is 75Ah.
Features
1) Bad environment application ability. Salt fog environmental
monitoring and high humidity environmental monitoring technology
were applied, and the monitoring data were sent to the lithium
battery management system. The system analyzed and processed the
detected data, started corresponding maintenance equipment
according to different conditions, and ensured the reliability and
safety of the lithium battery management system.
2) Rate-type discharge stability, the voltage difference is less
than 0.5V;
3) Flexible battery packs configuration technology. Battery pack
equalization and cascading technology for stable performance in
voltage withstand and current surge test and use. Especially
high-power inductive load test, fully meet the design criteria of
high reliability.
4) Advanced management architecture. In the balance of the battery
pack, the client-server structure is adopted, so that each battery
cell in the battery pack is under the same management, so that the
battery pack can achieve good consistency.
5) Advanced intelligent maintenance capabilities. The product has
maintenance-free, long operating life.
6) Highly reliable lithium battery system. The lithium iron
phosphate battery system is adopted, and the production and the
volumetric process are strictly controlled, and the consistency is
high and the safety is good. With long cycle life, it can be
charged quickly at 0.5C and discharged at 2C.
7) Green. Does not contain any heavy metals and rare metals,
non-toxic, non-polluting, in line with European ROHS regulations.
