Abstract:
1. A charging control device for electronic equipment, comprising: a rechargeable battery and at least one internal application requiring an application current for operation; a charging control module coupled to a charger capable of providing a charge current, wherein the charging control module comprises a control module and is coupled to the rechargeable battery and the charging control module is configured to control a charge to the rechargeable battery and configured to provide to the rechargeable battery a predetermined battery current, wherein the amount of charge and current provided is responsive to a temperature of the rechargeable battery within a predetermined interval, wherein the charging control module further comprises a current generator configured to provide an application with an application current from a received charge current when said electronic equipment is coupled to said charger; and a sensor module comprising a current sensor wherein the sensor module is coupled to the charging control module and wherein the sensor is configured to determine a consumed current by said application and to provide a first signal representative of said consumed current to the charging control module, wherein said charging control module is operative to provide said application with an application current equal to the current represented by said first signal, and wherein the charging control module is configured to maintain a constant charge when the battery temperature is outside said chosen interval, and operative to provide said application with an application current equal to the current represented by said first signal while providing said battery with a chosen battery current in order that the battery can be simultaneously charged when the battery temperature is within said chosen interval.
