The invention relates to the field of
energy engineering, in particular to a balance
maintenance system for online monitoring of a storage battery. The
system comprises a host and an acquisition module and the host is electrically connected with the acquisition module. The host comprises a
central processing unit, a
front panel face, a right panel face and an upper panel face; and the acquisitionmodule comprises an upper panel face, a
front panel face and a lower panel face. The
front panel face comprises a main equipment
liquid crystal display unit and a functional keyboard unit; a
USB interface, an
Ethernet interface, an upper computer RS485
data transmission port, a lower computer RS485
data transmission port and a main power supply interface are arranged on the right panel face; the upper panel face is provided with an
internal resistance test interface, a flexible connection test interface, a
voltage acquisition line interface, a current
test line interface and a temperature acquisition line interface. According to the balance
maintenance system for online monitoring of a storage battery, he
voltage and current of a storage
battery pack and the
voltage and internal resistanceof each single battery can be detected simultaneously and online balance maintenance, check
discharge maintenance and capacity test functions can be provided, so that the efficiency and
economic benefits of production work are improved.
