BATTERY MANAGEMENT SYSTEM AND METHOD AND BATTERY POWERED APPLIANCE INCORPORATING THE SAME
First Claim
1. A controller having a power supply including a battery for supplying power to said controller, said controller having an actuator circuit to actuate a device, where a processor powered from said battery controls said actuator circuit according to a schedule to actuate said actuator circuit;
- wherein said battery is connected via a charge circuit to selectively charge a storage capacitor, said storage capacitor being connected to said actuator circuit to selectively provide power from said storage capacitor to actuate said device, wherein when said actuator circuit is actuated said charge circuit is switched off, and when said actuator circuit is in stand-by (unactuated) said charge circuit is switched on;
where said power supply includes voltage monitoring to monitor capacitor voltage;
where said processor exerts over-riding control over actuation of said actuator circuit to prevent actuation of said device if the voltage of said capacitor does not reach and exceed a first predetermined level V1 of from 50% of the rated battery voltage within a predetermined time T1 after said charge circuit is again switched on after actuation of said device, said predetermined time being from 1.5 seconds to no more than 15 seconds.

Abstract
A controller (11) in a tap timer, having a battery (19) for connected via a charge circuit (23) to selectively charge a storage capacitor C2. The storage capacitor C2 is connected to an actuator circuit (25) to selectively provide power from the storage capacitor C2 to actuate a device M1. A processor (13) controls the actuator circuit (25) according to a pre-programmed schedule or on user demand. The processor monitors various parameters including charge rate of the capacitor C2 in order to determine battery condition, to determine if the processor (13) should next actuate the device (13).
