A power management system is provided, which can be used with batteries, in which electronic converters (6) extract the total amount of power required from a plurality of batteries (1) arranged in parallel and boost the battery voltage to the voltage required by the load. Thus it is not necessary to connect batteries in series to obtain a greater voltage than can be provided by one battery. Since the output of all the converters (6) is combined to supply the load, each battery can be used independently of the others and thus all batteries may be fully exhausted before being discarded or recharged. The user can be advised of the state of each battery and may therefore change batteries when they become exhausted before all the batteries are exhausted. Rechargeable batteries may be used together with dry batteries and the system conroller may be instructed to use rechargeable batteries preferentially using dry batteries only when no other source is available. |
