Power management for electric vehicles

An electric vehicle comprising:

• a load configured to receive power from a power source or a battery;
• a control circuit, coupled to said load, configured to manage said power by using a first control signal and a second control signal, said first control signal being generated by said control circuit based on a current of said battery, said second control signal being generated by said control circuit based on a voltage of said battery;
• and
• a first switch, coupled to said control circuit, configured to control connection of said battery to said power source and said load according to said first control signal,
• wherein said first control signal controls a voltage at a terminal of said first switch to maintain said current of said battery to be substantially equal to a current setting, and said second control signal controls said battery to switch between a first state and a second state.

A method for managing power in an electric vehicle, said method comprising:

• generating a first control signal based on a current of a battery operable for powering said electric vehicle;
• generating a second control signal based on a voltage of said battery;
• controlling, using a control circuit, connection of said battery to a power source and a load in said electric vehicle by controlling a switch based on said first control signal;
• maintaining said current of said battery to be substantially equal to a current setting by controlling a voltage at a terminal of said switch according to said first control signal;
• and controlling said battery to switch between a first state and a second state according to said second control signal.
