Document Type and Number:
WIPO Patent Application WO/2009/030101
Kind Code:
A1
Abstract:
An online passive maintaining device for large capacity sealed lead-acid accumulator.
The device includes a single chip circuit (1), an under-voltage protection circuit
(2), and a power output circuit (3), which are interconnected together. The single
chip circuit (1) includes a single chip (U2), a clock circuit, a voltage reference
circuit and a voltage detecting circuit. The voltage detecting circuit is connected
to a positive pole of the accumulator, an input terminal of the under-voltage
protection circuit (2) is connected to the positive pole of the accumulator,
an output terminal of a power output circuit (3) is connected to the under-voltage
protection circuit, and the circuits are separately connected to corresponding
ports of the single chip (U2). The single chip circuit (1) also signal receiving
and transmitting circuit connected to the corresponding port of the single chip.
