SUPERCAPACITOR TO ELECTROCHEMICAL HYBRID SYSTEM WITH SMART SELF-DISCHARGE CAPABILITY

A method for powering an electric vehicle including an electrochemical battery and one or more supercapacitor batteries includes determining self-discharge rate data for the one or more supercapacitor batteries and, in response to the self-discharge rate data satisfying at least one threshold condition, notifying a user to charge the one or more supercapacitor batteries, otherwise performing operations including: measuring current within a first path connecting the electrochemical battery to the electric vehicle; storing data representing the measured current in a database; determining a current use pattern from stored current data in the database; and in response to the current use pattern satisfying a first switching condition, switching in the one or more supercapacitor batteries in place of the electrochemical battery.
