Direct-current uninterruptible power source unit
First Claim
1. A DC uninterruptible power source unit, which supplies a backup power to a load device on occurrence of a power supply failure, the load device being operated by a DC power supplied from an AC/DC conversion device converting an AC power supplied from an AC power source into the DC power, the DC uninterruptible power source unit comprising:
- a predetermined number of battery packs each comprising;
a group of batteries composed of a plurality of rechargeable batteries so as to obtain an output voltage corresponding to a power source voltage required by the load device;
a pack case for receiving the group of the batteries;
a memory unit for storing information of the group of the batteries; and
a detector for detecting an operating condition of the group of the batteries;
a case equipped with a battery pack receiving section removably accommodating the predetermined number of battery packs separately from a certain direction;
a connector for connecting a power line and an information transmission line to the mounted battery packs;
a charge circuit for supplying a charge power to the battery packs;
a discharge circuit for adjusting a battery power outputted from the battery packs to a predetermined voltage; and
a power source controller for performing a power control by controlling operations of the charge circuit, the discharge circuit, the battery packs, and entire operations of the uninterruptible power source unit, the connector, the charge circuit, the discharge circuit, and the power source controller being accommodated in the case.

Abstract
Battery packs with a plurality of rechargeable batteries connected in series so as to obtain a voltage required by a load device are detachably accommodated in a case. The battery packs are connected in parallel and each output thereof is modified to a predetermined voltage by a discharge control section. The battery packs are connected to a power source line of the load device. Each battery pack is connected through an information transmission line to a power source control section where charge and discharge thereof are controlled, as well as the lifetime is judged. Thus, only the lifetime-judged battery pack is replaced.
