In accordance with the invention, the device is powered by two storage or charge receiving devices. One of these devices is capable of receiving a substantial charge very rapidly while the other device requires a longer time to receive a charge. The advantage is that the powered device can be used almost instantly and continually while at the same time rebuilding electrical charge. The present invention further relates to a system for protecting the charging device from being damaged from an electrical surge, such as from a lightening strike. | 2011-03-03 |
20110050168 | CHARGE CONTROL METHOD FOR VEHICLE AND DEVICE THEREOF - The present invention provides a charge control method for a vehicle that can increase efficiency in the use of limited power. The charge control method, includes: determining, by charge control device, a charging capability of a charger selected in accordance with charge request information transmitted from the vehicle among a plurality of chargers positioned in an area corresponding to the vehicle; and controlling the charger to charge the vehicle with the amount of requested power corresponding to the charge request information in accordance with the charging capability. | 2011-03-03 |
20110050169 | SECONDARY BATTERY DEVICE AND VEHICLE - According to one embodiment, the power supply management portion includes a timer configured to output an ON signal every time set by the control circuit, an OR circuit configured to receive supply of an output signal from the timer, an external signal supplied from outside, and a switch control signal output from the control circuit, and a switch circuit configured to switch output of the power source voltage from an external power source according to an output signal from the OR circuit, and the control circuit turns on a switch control signal after confirming which of the output signal from the timer or the external signal has turned on the switch circuit and turns off the switch control signal when both of the output signal from the timer and the signal supplied from outside are turned off. | 2011-03-03 |
20110050170 | Electromechanical Vampire Proof Battery Charger System - A method of eliminating vampire energy loss in battery charges is provided. Vampire energy loss occurs when an electronic or mechanical machine consumes energy while not being utilized for the purpose of its existence, for example, energy loss in re-charging consumer electronic devices. By employing the use of an electromechanical switching method that creates a conductive short circuit to the charger after disconnecting the charged target device, the vampire or no load energy loss can be eliminated with or without disconnecting the charger. | 2011-03-03 |
