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.

Systems and methods are provided for electrochemical battery testing in supercapacitor-toelectrochemical hybrid systems, which may be provided in an electric vehicle. Such systems may include at least one electrochemical battery and an supercapacitor adder module and connections, and electrochemical battery testing module. In conjunction with a supercapacitor adder module, the electrochemical battery testing module applies a variety of tests and measures various parameters of one or more electrochemical batteries connected to an electric vehicle.

An electric vehicle battery charging system, comprising digital map subsystem, operating software that incorporates the digital map subsystem, a plurality of charging units, and a controlling unit that mainly handles booking related matters. The booking flow works as below steps: (a) searching step: to search every possible available charging unit, (b) confirming step: to confirm the electric vehicle arrives at selected charging unit at an acceptable time, (c) charging step: to complete the whole charging session. The system further comprises a preventing measure that prevents the charging units from being occupied unruly and an enhancing measure that enhances charging efficiency out of booking accuracy.
