An HVAC system to be installed in a vehicle comprises a battery management controller. The battery management controller comprises at least one connection for electrically coupling a first power source with a first voltage; at least one connection for electrically coupling a second power source with a second voltage; and a first memory storage device configured to record data collected by the battery management controller. The battery management controller is configured to run a temperature control system and to supply power to the temperature control system from a combination of the first and second power sources with a combined voltage, and wherein the second power source is disconnected when the combined voltage drops below a predetermined amount.

HVAC system controlled by a battery management system

An installable HVAC system used for a vehicle is disclosed. The HVAC system includes a housing, a compressor, a motor operatively coupled to the compressor; a condenser in fluid communication with the compressor; and a power management controller configured to run the motor with power from a given power source. The compressor, the motor, the condenser, and the power management controller are located within the housing. The housing is configured to attach to an existing HVAC system of the vehicle.

Installable HVAC systems for vehicles

A variable speed air compressing system includes a compressor, a motor configured to actuate the compressor, and a rectifier configured to receive alternating current from a first power source and to provide rectified direct current having a first voltage. The system also includes an inverter configured to receive the rectified direct current and to receive direct current from a second power source having a second voltage. The inverter is configured to provide alternating current to the motor. The alternating current provided to the motor is based on the rectified direct current if the first voltage is greater than the second voltage and the alternating current is based on the direct current from the second power source if the second voltage is greater than the first voltage.

Variable speed air compressing system having AC and DC power sources

The disclosed power system may comprise first and second batteries; an electrical power generator; an electrical load powered by at least one of the first battery, the second battery or the electrical power generator; a converter; and a battery management controller. The converter is connected to both the first and second batteries and configured to operate in a neutral mode, a first battery charging mode, or a second battery charging mode. The converter is configured to create a voltage difference between the first and second batteries in the charging modes. The battery management controller is configured to monitor the voltage of the first battery and the voltage of the second battery and/or to monitor current flow to and from the first and second batteries. The controller controls operation of the converter to operate in the neutral mode, the first battery charging mode or the second battery charging mode.
