◆ Features
Wireless transmission storage battery
testing system is comprehensive fruit integrating with several
technologies of battery measurement, wireless communication,
computer information processing and etc.
·Patent technology, adopt wireless communication for transfer
data, easy operation and safety.
·Real-time monitoring cell voltage, quick and accurate data
collection, record the change at each moment during battery
charge and discharge, guarantee accurate judgment of battery
performance, and prevent from measurement error caused by
wiring.
·Complete anti-opposition measure, even if module measurement
signal line is connected oppositively, it could not cause
the damage of battery and module.
·High-accuracy of wireless module (16 bit AD), low power
consumption, small volume, light weight, easy operation, and
reliable security.
·Single unit of system could test several packs of batteries
simultaneously, the total of measuring battery quantity could
be up to255, and with high testing efficiency.
·The system possesses RS232/485 communication interface,
which could perform real-time data communication, or be controlled
by other intelligent equipment.
