摘要： A method, an apparatus and a system for using a plurality of subscriber identity module (SIM) cards is provided. The use of the plurality of subscriber identity module (SIM) cards comprises stop using a first SIM card and start using a second SIM card when a first event trigger occurs; and stop using the second SIM card and start using an operational SIM card when a second event trigger occurs. The operational SIM card can be the first SIM card, the second SIM card or another SIM card. The SIM cards can be placed in a wireless communication system. The SIM cards can also be placed in at least one external device and the external device can be connected to the wireless communication system.

摘要： The present invention discloses methods and systems for managing power supply at a device. The device is capable of receiving power via a plurality of power inputs. The device first determines whether or not a first condition is satisfied. A first switch is maintained in a closed position if the first condition is satisfied. When the first switch is in a closed position, the device is capable of receiving power from a first power supply. Alternatively, when the first condition is not satisfied, the device determines whether or not a second condition is satisfied. If the second condition is satisfied, the first switch is maintained to be in a closed position. If the second condition is not satisfied, the first switch is opened after a predefined time period.

摘要： To prevent theft and/or leakage of electricity and to distribute electricity for recharging electric vehicles, the present invention discloses methods and systems for enabling and disabling a plurality of relays at a system. The system comprises a power supply, at least one ammeter, a power supply enabler and at least one power controller. The required steps include measuring current drawn by the plurality of loads by one or more ammeters. The power controller independently enables or disables each of the plurality of relays according to the instructions received. The power supply enabler enables or disables power supply to the system substantially based on the amount of current being drawn by the system.

摘要： The present invention discloses methods and systems for scheduling and distributing power for electric vehicle chargers, through enabling and disabling a plurality of relays at a system. One of the criteria to allow an authenticated user to use an electric vehicle charger is whether there is enough electricity capacity. When the user is allowed to use a scheduled electric vehicle charger, its location is then sent to the user. Alert messages can be generated if charging does not begin within a first time limit and the cancellation of a reservation will take place if the second time limit is reached.
