Power control system for electrical apparatus

An electrical apparatus comprising:

• a supply circuit to:
• draw current from an alternating current source at a level that is below a predetermined threshold;
• use a proportion of the drawn current to continuously power an electrical apparatus at below the predetermined threshold;
• and
• a power controller to supply a charge current to the rechargeable battery module using a remainder of the proportion of the drawn current that powers the electrical apparatus, and to supply power to the electrical apparatus from the rechargeable battery module independent of the drawn current from the alternating current source, the supplied power of the rechargeable battery module meeting a power requirement of the electrical apparatus that would otherwise exceed the predetermined threshold.

A method for controlling power to an electrical apparatus, the method comprising:

• drawing current from an alternating current source at a level that is below a predetermined threshold;
• using a proportion of the drawn current to continuously power an electrical apparatus at below the predetermined threshold, while supplying a charge current for the battery using a remainder of the drawn current;
• and
• independently supplying power from the battery to the electrical apparatus at a level that exceeds the predetermined threshold during intervals in which a power requirement of the electrical apparatus exceeds the predetermined threshold.
