Abstract

Example apparatus and methods are disclosed for a vehicle-based smart cooler. An example disclosed cooler includes an electric cooling unit, a plurality of sensors, a wireless node, and a cooling control unit. The example wireless node communicatively couples to the vehicle. The example cooling control unit monitors a charge margin of the vehicle and, in response to the charge margin being below a threshold, activates a power management technique.

First claim

What is claimed is:

1. A cooler for a vehicle comprising:
an electric cooling unit;
a plurality of sensors;
a wireless node to communicatively couple to the vehicle; and
a cooling control unit to:
monitor a charge margin of the vehicle, the charge margin being a difference between a current power bus voltage of the vehicle and voltage at which a battery of the vehicle cannot provide a starter current; and
in response to the charge margin being below a threshold, activate a power management technique.

2. The cooler of claim 1 , wherein the electric cooling unit includes a thermoelectric cooler.

3. The cooler of claim 1 , wherein the plurality of sensors includes an internal temperature sensor to measure a first temperature of an interior of the cooler, and an ambient temperature sensor to measure an ambient temperature around the cooler.

4. The cooler of claim 3 , wherein the plurality of sensors includes a lid sensor to detect a position of a lid of the cooler, a contents temperature sensor to measure a second temperature of an item in cooler, and contents sensor to detect when the item is in the cooler.

5. The cooler of claim 3 , wherein the electric cooling unit is to draw a first current from the vehicle based on a difference between a target temperature of an interior of the cooler and the ambient temperature.

6. The cooler of claim 1 , wherein the cooling control unit is to:
monitor an internal temperature of the cooler; and
when the power management technique is active, in response to the internal temperature raising above a temperature threshold, send a warning message to the vehicle.

7. The cooler of claim 1 , wherein the cooling control unit is to:
monitor a surface temperature of an item inside the cooler;
in response to determine that the surface temperature of the item is outside a safe temperature range for a threshold period of time, send a warning message to the vehicle.

8. The cooler of claim 1 , wherein the cooling control unit is further to transmit a signal to the vehicle to lower power consumed by an HVAC system of the vehicle in response to the charge margin being below a threshold.

9. A cooler for a vehicle comprising:
an electric cooling unit;
a plurality of sensors;
a wireless node to communicatively couple to the vehicle; and
a cooling control unit to:
monitor a charge margin of the vehicle; and
in response to the charge margin being below a threshold, request the vehicle to increase a number of revolutions per minute of an engine of the vehicle.

10. The cooler of claim 9 , wherein the cooling control unit requests the vehicle increase the number of revolutions per minute of the engine at a first time, and wherein the cooling control unit is to, at a second time after the first time, in response to the charge margin being lower at the second time than the charge margin at the first time, send a warning message to the vehicle, the warning message to include suggestions of actions to reduce power consumption of other subsystems of the vehicle.

11. A cooler for a vehicle comprising:
an electric cooling unit;
a plurality of sensors;
a wireless node to communicatively couple to the vehicle; and
a cooling control unit to:
monitor a charge margin of the vehicle; and

responsive to the charge margin being below a threshold, repeatedly turn the electric cooling unit off for a first time period and on for a second time period, the first time period longer than the second time period.

12. A cooler for a vehicle comprising:
an electric cooling unit;
a plurality of sensors;
a wireless node to communicatively couple to the vehicle; and
a cooling control unit to:
monitor a charge margin of the vehicle; and
in response to the charge margin being below a threshold, activate a power management technique, wherein the cooling control unit is to receive a temperature set point from the vehicle;
determine a temperature difference between an ambient temperature around the cooler and the temperature set point;
determine, based on the temperature difference, whether the cooling unit has a capacity to cool the interior of the cooler to the temperature set point; and
in response to determining that the cooling unit does not have the capacity to cool the interior of the cooler to the temperature set point, send an error warning message to the vehicle.
