Storage battery unit
First Claim
1. A storage battery unit comprising:
- a storage battery in which a generation element including a positive electrode and a negative electrode is housed in a battery jar and positive and negative output terminals are mounted to a lid of said battery jar; and
a monitoring device that monitors a state of said storage battery using an output of said storage battery as an input,wherein a starting circuit is inserted between the output terminal of said storage battery and an input terminal of said monitoring device, andsaid starting circuit includes a main switch that holds an OFF state in a state before a load exceeding a set value is connected to said storage battery and interrupts supply of electric power from said storage battery to said monitoring device, and a switch drive circuit that detects a reduction in terminal voltage of said storage battery that occurs when said load is connected to said storage battery, and sets said main switch to an ON state.

Abstract
A storage battery unit (1) including a storage battery (2) and a monitoring device (3) that monitors a state of the storage battery using an output of the storage battery as an input, wherein, in order to prevent the monitoring device from consuming electric power in a state before use of the storage battery and prevent nonfunctioning of the monitoring device in use of the storage battery, a starting circuit (4) is provided between the storage battery and the monitoring device (3), the starting circuit including: a main switch that holds an OFF state in a state before a load is connected to the storage battery and interrupts supply of electric power from the storage battery (2) to the monitoring device; and a switch drive circuit that detects a reduction in terminal voltage of the storage battery that occurs when the load exceeding the set value is connected to the storage battery, and sets the main switch to an ON state.
