Sleep mode: the battery will be in sleep mode if any of the following
conditions are met 1) The battery or battery pack over discharge protection
lasts for 30 seconds and is not released. 2) Press the power on / off button
for 3 seconds and release. 3) The minimum voltage of the battery is lower than
the “sleep voltage” setting in the setting,
without charging and discharging. 4) Standby for more than 24 hours without
charging and discharging. 5) Switch to the upper computer for sleep manually.
Wake up: the battery will exit sleep mode if any of the following conditions
are met 1) Charger is plugged in; The charger voltage is greater than 48V. 2)
Press the power on / off button for 3 seconds and release. 3) Plug in the
communication cable and open the upper computer software (not available if it
is
under over discharge protection).
Note: if over discharge protection is enabled, the battery will be in sleep
mode. The battery will wake
up automatically every 4 hours and turn on the charge / discharge MOS. If
charging is available, the
battery will be charged, otherwise it will return to sleep mode. If it has
been awakened 10 times but
cannot be charged, the battery will not wake up again automatically.

The signal line connected to the inverter should use RS485 communication line
or CAN communication line. If it is necessary to use batteries in parallel:
RS485 cable shall be used to connect the parallel communication port. Refer to
the communication line parallel diagram; The address of the battery needs to
be set. Refer to the dial switch setting table for address setting.

7. Active Equilibrium Function
7.1 Overview
Because the battery capacity, internal resistance, voltage and other parameter values are not completely consistent, this difference causes the battery with the smallest capacity to be easily overcharged and discharged during charging, and the smallest battery capacity becomes smaller after damage, entering a vicious cycle. The performance of single battery directly affects the charge and discharge characteristics of the whole battery and the reduction of battery capacity. BMS without balance function is just a data collector, which is hardly a management system. BMS active equalization function can realize the maximum continuous 1A equalization current. Transfer the highenergy single battery to the low-energy single battery, or use the whole group of energy to supplement the lowest single battery. During the implementation process, the energy is redistributed through the energy storage link, so as to ensure the battery consistency to the greatest extent, improve the battery life mileage and delay the battery aging.
