Abstract:
An electrical apparatus incorporates a first rechargeable battery (11) and a second rechargeable battery (12) connected in parallel with the first rechargeable battery (11), the second rechargeable battery (12) having an allowable maximum discharge current larger than that of the first rechargeable battery (11). The electrical apparatus includes: a power supply path (15a) configured to input power supplied from the first rechargeable battery (11) and from the second rechargeable battery (12) to a load (15); and a discharge current limiting circuit connected serially with the first rechargeable battery (11) and configured to perform control in such a manner that a discharge current flowing from the first rechargeable battery (11) to the second rechargeable battery (12) and/or to the power supply path (15a) does not exceed the maximum discharge current of the first rechargeable battery (11).
