## Abstract

Processes for converting and adapting a vehicle into a hybrid-driven vehicle include coupling an electric motor generator unit to an engine of the vehicle, including to a through-bolt extending through a crankshaft pulley. Also included is a process for converting a vehicle's mechanically-driven air conditioning compressor to operate as an electro-mechanical air conditioning compressor by detaching the air conditioning compressor from the crankshaft and operating the air conditioning compressor using an electric motor. A temperature of rechargeable vehicle batteries of an alternate power unit of the vehicle is managed and maintained at a predetermined desired temperature.

## Claims

### Claim 1

A process for managing the temperature of rechargeable vehicle batteries,
comprising the steps of:
providing an alternate power unit comprised of rechargeable batteries disposed within a housing;
detecting a temperature of an interior of the housing;
cooling the interior of the housing when the detected temperature is above a predetermined temperature; and
heating the interior of the housing when the detected temperature is below a predetermined temperature.

### Claim 2 (depends on 1)

The process of claim 1, wherein the step of cooling the interior of the housing comprises the steps of passing air through an evaporator to cool the air and directing the cooled air into the housing to cool the batteries.

### Claim 3 (depends on 2)

The process of claim 2, including the step of passing a refrigerant from a low pressure line of an air conditioning compressor of the vehicle through the evaporator.

### Claim 4 (depends on 1)

The process of claim 1, including the step of providing an alternate power unit dedicated air conditioning unit.

### Claim 5 (depends on 4)

The process of claim 4, wherein the alternate power unit dedicated air conditioning unit comprises a condenser, a compressor, an accumulator, and an evaporator to cool the interior of the housing of the alternate power unit.

### Claim 6 (depends on 1)

The process of claim 1, wherein the cooling step includes cooling the interior of the housing when the detected temperature exceeds approximately 90 degrees Fahrenheit.

### Claim 7 (depends on 1)

The process of claim 1, wherein the heating step comprises the step of selectively providing electricity to electrical heating elements to heat the interior of the housing of the alternate power unit.

### Claim 8

A process for managing the temperature of rechargeable vehicle batteries, comprising the steps of:
providing an alternate power unit comprised of rechargeable batteries disposed within a housing;
passing a refrigerant from a low pressure line of an air conditioning compressor of the vehicle through an evaporator associated with the housing;
detecting a temperature of an interior of the housing;
passing air through the evaporator to cool the air and directing the cooled air into the housing to cool the batteries when the detected temperature is above a predetermined temperature; and
heating the interior of the housing when the detected temperature is below a predetermined temperature.

### Claim 9 (depends on 8)

The process of claim 8, wherein the cooling step includes cooling the interior of the housing when the detected temperature exceeds approximately 90 degrees Fahrenheit.

### Claim 10 (depends on 8)

The process of claim 8, wherein the heating step comprises the step of selectively providing electricity to electrical heating elements to heat the interior of the housing of the alternate power unit.

### Claim 11

A process for managing the temperature of rechargeable vehicle batteries,
comprising the steps of:
providing an alternate power unit comprised of rechargeable batteries disposed within a housing;
providing an alternate power unit dedicated air conditioning unit comprising
a condenser, a compressor, an accumulator, and an evaporator;
detecting a temperature of an interior of the housing;
cooling the interior of the housing when the detected temperature is above a predetermined temperature by passing a refrigerant through the evaporator to cool air, and directing the cooled air into the interior of the housing; and
heating the interior of the housing when the detected temperature is below a predetermined temperature.

### Claim 12 (depends on 11)

The process of claim 11, wherein the cooling step includes cooling the interior of the housing when the detected temperature exceeds approximately 90 degrees Fahrenheit.

### Claim 13 (depends on 11)

The process of claim 11, wherein the heating step comprises the step of selectively providing electricity to electrical heating elements to heat the interior of the housing of the alternate power unit.
