2. Introduction to Product
2.1 Intended Purpose
The battery is a 6.5kWh LiFePO4 pack. It has a 48V battery module as the main power
supply unit which composed of 32 64Ah cells in two parallel and sixteen serial connect
(2P16S). Battery coordinates with PV, PCS, Grid and loads in the residential energy storage
system. The four typical application scenarios are as shown below:
2.2 Function
Compared with normal batteries, the battery is characterized with better charging and
discharging performance, longer cycle life and less self-discharging loss. The build-in BMS
can monitor battery operation status and alarm timely to avoid operation out of limit. Two
batteries can be parallel-connected to expand energy and power of energy storage system.
Battery realizes communication with PCS via CAN network port.
The energy produced by PV is
optimized to supply loads. The excess
energy is used to charge battery, then
export to grid.
Battery powers loads at nighttime when
there is no PV. If battery energy is
insufficient, it can supply loads together
with grid.
When grid falls, battery and PV can
power loads.
Battery can be charged by grid. Users are
suggested to store energy from grid to battery
when electricity price is relatively lower.
