| 摘要 |
A preferred embodiment of the renewable direct current power source of the present invention includes input terminals which are adapted to receive recharge voltage from a relatively low voltage power source and output terminals which are adapted to provide a battery-output voltage, with the battery-output voltage being higher than the recharge voltage. Preferably, a plurality of rechargeable battery cells are electrically interconnected between the input terminals and the output terminals and are configured to electrically interconnect with each other in series during discharge. A method aspect also is provided.
