Abstract
Disclosed herein are electric vehicles with various characteristics. For example, electric vehicles with at least two energy storage systems are described. As another example, electric vehicles with liquid temperature regulated battery packs are described. As yet another example, electric vehicles with high voltage battery limit optimization are disclosed. And, as another example, electric vehicles with dual-battery system charge management are described.
Claims20
An electric vehicle comprising:
- a first battery;
- at least one electric motor capable of propelling the vehicle, the motor powered by the first battery in a charge depleting manner;
- a second battery physically separate from the first battery;
- and
- an HVAC system, the HVAC system configured to be powered by the second battery in a charge depleting manner while the first battery is powering the motor.
A method of powering an electric vehicle while the vehicle is traveling, the method comprising:
- discharging a first battery system by drawing current from the first battery system to power one or more motor loads;
- and
- simultaneously discharging a second battery system by drawing current from the second battery system to power one or more non-motor loads, the second battery system being electrically isolated from the first battery system.
A method of charging an electric vehicle having at least two energy stores that are coupled together by a DC-DC convertor, the method comprising:
- receiving current from a charging connection coupled to the electric vehicle;
- routing a first current directly to a first battery;
- and
- routing a second current directly to a second battery that is physically separated from the first battery, wherein no current is routed through the DC-DC convertor during at least some of the charging process.
