Method and apparatus for implementing smart management of a rechargeable battery

An apparatus for implementing smart management of a rechargeable battery, wherein the apparatus comprises:

• a central processing unit respectively connected to a voltage detector, a temperature detector for measuring the surface temperature of the rechargeable battery, a current detector for measuring the terminal voltage and a current flow detector for measuring the flow of current in charge/discharge of the rechargeable battery;
• a memory for saving the parameter values including the terminal voltage, temperature and charge/discharge current with respect to the rechargeable battery;
• a charge controller connected between the rechargeable battery and an external power input and whose operation is controlled by the central processing unit (1);
• whereby if the surface temperature of the rechargeable battery is between a predetermined upper and lower temperature limit in the charging mode, the central processor unit activates the charge controller to provide constant current for charging the rechargeable battery;
• a trickle charger connected between the rechargeable battery and the external power input whose operation is controlled by the central processing unit;
• whereby if the surface temperature of the rechargeable battery is below a predetermined lower temperature limit, the central processing unit turns off the charge controller and activates the trickle charger for slow charging the rechargeable battery with a small current;
• and
• a discharge controller connected between the central processing unit and the rechargeable battery;
• whereby if the rechargeable battery is below the discharge limit, the central processing unit (1) disables the controller to prevent irreversible damage to the rechargeable battery;
