Abstract

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.

Claims

1. An HVAC system to be installed in a vehicle comprising:

a battery management controller comprising;

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;

wherein the battery management controller is configured to run a temperature control system when an engine of the vehicle is turned off and to supply power to the temperature control system when the engine is turned off 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.

2. The HVAC system of claim 1, wherein the battery management controller collects voltage, current, and temperature data, and wherein the data is transmitted to the first memory storage device.

3. The HVAC system of claim 1, wherein the first memory storage device is connected to an input/output device configured to allow the first memory storage device to transmit and receive data to and from a second memory storage device.

4. The HVAC system of claim 3, wherein the second memory storage device is a USB memory stick, hard drive, or flash card.

5. The HVAC system of claim 1, further comprising an integral timing device connected to the battery management controller, wherein the integral timing device is configured to regulate the HVAC system when the integral timing device reaches a predetermined time value.

6. The HVAC system of claim 1, further comprising a user interface connected to the battery management controller and configured to alert a vehicle user about voltage, current, and temperature values.

7. The HVAC system of claim 6, wherein the user interface is configured to alert a vehicle user when the combined voltage value reaches a predetermined amount.
