In FIG. 1, the main power switch 15 of the battery body, the DC jack 22 that is a DC power input part for storing electricity, the AC inlet 21 that is an AC power input part, an emergency light 31 that can be turned on during a power failure, and an indicator 70, two AC100V outlets 41 and 42 (corresponding to an AC power supply output unit) that output the AC voltage input from the AC inlet 21 as it is during normal operation, and a DC power supply output that outputs a DC voltage from the power storage unit 35 A USB output terminal 43 and a cigar socket 44 are arranged as a unit. The AC 100V outlets 41 and 42 convert the DC voltage output from the power storage unit 35 into an AC voltage by the inverter unit 36 at the time of a power failure, thereby enabling AC output. Reference numeral 81 denotes an LED light indicating the operation state of the inverter unit 36. For example, the green state indicates that the inverter unit 36 is in a normal state and the red state indicates an error state. Reference numeral 82 denotes a switch for turning ON / OFF the inverter unit 36. This switch is turned on when sine wave output is desired.

  The DC jack 22 can be connected to a plurality of types of direct current power sources. Note that the DC power supply input unit is not limited to the DC jack, and may be configured with other input terminals.

  Reference numeral 16 denotes an emergency light ON / OFF switch. Reference numeral 17 denotes an automatic / manual operation switch for automatically or manually turning on / off the emergency light 31. When the automatic / manual switch 17 is “manual”, the emergency light ON / OFF switch 16 is turned ON / OFF. In addition, when the automatic / manual switch 17 is “automatic”, the emergency light 31 automatically blinks (or may be turned on) in the event of a power failure.

  A handle 12 is formed on the top surface of the housing 10. The indicator 70 includes an LED lamp (not shown) indicating whether charging is in progress and an LED lamp (not shown) indicating the remaining battery level (charge amount).

  Next, the internal structure will be described with reference to FIG. In the housing 10, a first cover 10a and a second cover 10b are connected by a screw 11a and a female screw portion 11b corresponding to the screw 11a. In FIG. 2, the screw 11a is removed and the internal structure is exposed. By removing the second cover 10b, the battery (power storage unit) 35, the inverter unit 36, and the control board 50 are exposed. Here, since the battery 35 is detachably incorporated, it can be easily removed and easily replaced with a new battery. The battery 35 is a lead-acid battery and a deep cycle battery, and is a shielded battery that hardly leaks liquid. Note that other types of batteries may be used as the battery 35.

Further, a member other than the battery 35 can be covered with a cover (not shown) to improve the handleability when the battery is replaced, and the member other than the battery (inverter, control board, etc.) is not touched. May be.

<During normal operation>
Next, the functional configuration shown in FIG. 3 will be described. First, the normal operation will be described. The home AC 100V power source 102, the AC inlet 21, and an AC cord (not shown) are connected. The AC inlet 21 is connected to the AC 100V outlets 41 and 42 via the UPS switch 58. During normal operation, the AC voltage of the household AC 100V power source 102 is directly output from the AC 100V outlets 41 and 42. A polyswitch (non-destructive overcurrent protection device) or a predetermined fuse (not shown) is disposed between the AC inlet 21 and the UPS switch 58 in consideration of the effects of power supply stability, lightning strikes, and the like. . The AC inlet 21 may be a fuse type.

  The UPS switch 58 is provided on the first wiring 61 from the AC inlet 21 to the AC 100V outlets 41 and 42. When the power failure detection unit detects a power failure and the power failure detection unit detects the power failure, the AC inlet 21 is provided. And the first wiring 61 between the AC 100V outlets 41 and 42 is cut off, and instead, the second wiring 62 from the power storage unit 35 is connected to the AC 100V outlets 41 and 42. A known UPS switch may be applied as the UPS switch 58.

<Power storage method>
Next, a method for storing power in the battery 35 will be described. A DC power supply 101 and a DC jack 22 are connected. Examples of the DC power source 101 include a cigarette lighter and a solar panel, and may be an AC 100V to 240V power source via an AC adapter. The DC jack 22 and the control unit 51 are connected, and the control unit 51 detects the input DC voltage value and gives a command for adjusting the voltage value to each component unit according to the DC voltage value. For example, when the battery 35 is of 12V and 20Ah specifications, the control unit 51 turns on the upconverter 52 and boosts DC12V from the cigarette lighter to DC17V by the upconverter 52. When boosting is not necessary, the up-converter 52 is OFF and the input DC voltage is input to the subsequent DC-DC converter 53 as it is. The DC-DC converter 53 converts the current into a direct current (or direct current voltage) suitable for the storage (charging) current (for example, 1/10 of the storage capacity) to the battery 35. The output (DC current, DC voltage) of the DC-DC converter 53 is input to the battery 35, and storage (charging) is started in the battery 35. The up converter 52 and the DC-DC converter 53 correspond to a power storage adjustment unit. The control unit 51 is composed of, for example, a microcomputer, and performs ON / OFF control of the up converter 52, the DC-DC converter 53, and the like.

  When power storage (charging) is started, the LED light indicating that the indicator 70 is being charged is turned on, and the charging capacity is turned on and displayed stepwise by the LED light. At this time, the control unit 51 performs ON / OFF control of the LED light of the indicator 70. When the battery 35 reaches full charge, the power storage is completed, and the LED light of the indicator 70 indicating the full charge is turned on. During power storage, the input power source (DC 5 V) of the control unit 51 uses the output voltage from the DC-DC converter 56. The output power from the DC jack 22 is input to the input power source of the DC-DC converter 56.

<Operation at power failure>
Next, the operation at the time of power failure will be described. First, the second wiring 62 will be described. On the second wiring 62 starting from the battery 35, a power storage unit side switch unit 54, a circuit breaker (breaker) 55, and an inverter unit 36 are arranged in this order. The power storage unit side switch unit 54 is always used in the UPS mode regardless of whether there is a power failure or not, and the inverter unit 36 is always turned on so that it can be instantly backed up in the event of a power failure. By turning on the breaker 55, the switch of the power storage unit side switch unit 54 is automatically turned on (if the battery has capacity). When a power failure occurs, the power failure detection unit of the UPS switch 58 detects the power failure, the switch unit disconnects the first wiring 61, and connects the second wiring 62 to the AC 100 V outlets 41 and 42. Thereby, the battery 35 and the AC100V outlets 41 and 42 are electrically connected. The control unit 51 monitors the battery voltage value, and performs ON / OFF control of the LED light of the indicator 70 so as to appropriately indicate the remaining battery level (charge amount) of the battery 35. The inverter unit 36 converts the DC12V output voltage from the battery 35 into a sinusoidal AC100V. The converted sinusoidal AC100V is output from the AC100V outlets 41 and 42.

  Further, the second wiring 62 and the cigar socket 44 are connected, and DC 12 V is output from the cigar socket 44. Further, the second wiring 62 and the USB output terminal 43 are connected via the DC-DC converter 56, and the DC-DC converter 56 converts DC12V to DC5V, and the DC5V is output from the USB output terminal 43.

  Further, the control unit 51 controls ON / OFF of the emergency light 31. When the light operation switch 17 is set to automatic, the control unit 51 controls to turn on the emergency light 31 at the time of power failure. During a power failure, the input power (DC 5 V) of the control unit 51 uses the output voltage from the DC-DC converter 56. The breaker 55 has two switches, one of which is directly connected from the battery 35 to the DC-DC converter 56, and the control unit 51 moves when the breaker 55 is turned on.
