## Abstract

A system comprises a computer having a processor and a memory, the memory storing instructions executable by the processor to receive, from a charge-requesting vehicle, a charge request, determine a suggested provider pool for fulfilling the charge request, the suggested provider pool including multiple suggested charge-providing vehicles, send suggested provider data to the charge-requesting vehicle, the suggested provider data identifying the multiple suggested charge-providing vehicles, receive, from the charge-requesting vehicle, a provider selection identifying one of the multiple suggested charge-providing vehicles as a selected charge-providing vehicle, identify transfer parameters for a battery charge transfer from the selected charge-providing vehicle to the charge-requesting vehicle; and send a transfer initiation message to instruct the selected charge-providing vehicle to initiate the battery charge transfer according to the transfer parameters.

## Claims

### Claim 1

A system, comprising:
a computer having a processor and a memory, the memory storing instructions executable by the processor to:
receive, from a charge-requesting vehicle, a charge request;
determine a suggested provider pool for fulfilling the charge request, the suggested provider pool including multiple suggested charge-providing vehicles;
send suggested provider data to the charge-requesting vehicle, the suggested provider data identifying the multiple suggested charge-providing vehicles;
receive, from the charge-requesting vehicle, a provider selection identifying one of the multiple suggested charge-providing vehicles as a selected charge-providing vehicle;
identify transfer parameters for a battery charge transfer from the selected charge-providing vehicle to the charge-requesting vehicle;
send a transfer initiation message to instruct the selected charge-providing vehicle to initiate the battery charge transfer according to the transfer parameters;
actuate at least one of a vehicle camera, a vehicle light, and a vehicle microphone when the charge-providing vehicle is within a specified distance of the charge-requesting vehicle; and
output a performance rating for the charge-providing vehicle after the battery charge transfer is completed.

### Claim 2 (depends on 1)

The system of claim 1, the charge request comprising one or more charge request parameters.

### Claim 3 (depends on 2)

The system of claim 2, the memory storing instructions executable by the processor to:
determine a candidate provider pool based on the one or more charge request parameters; and
select the multiple suggested charge-providing vehicles of the suggested provider pool from among a plurality of vehicles of the candidate provider pool.

### Claim 4 (depends on 3)

The system of claim 3, the memory storing instructions executable by the processor to determine the candidate provider pool based on charge requestor data for the charge-requesting vehicle.

### Claim 5 (depends on 2)

The system of claim 2, the one or more charge request parameters including a charge request parameter that indicates a location for the battery charge transfer.

### Claim 6 (depends on 2)

The system of claim 2, the one or more charge request parameters including a charge request parameter that indicates an amount of charge to be transferred via the battery charge transfer.

### Claim 7 (depends on 2)

The system of claim 2, the one or more charge request parameters including a charge request parameter that indicates a duration for the battery charge transfer.

### Claim 8 (depends on 1)

The system of claim 1, the memory storing instructions executable by the processor to select the multiple suggested charge-providing vehicles based on confidence scores associated with the multiple suggested charge-providing vehicles.

### Claim 9 (depends on 8)

The system of claim 8, the suggested provider data indicating the confidence scores associated with the multiple suggested charge-providing vehicles.

### Claim 10 (depends on 1)

The system of claim 1, the memory storing instructions executable by the processor to:
send a confirmation request to the selected charge-providing vehicle;
receive a confirmation from the selected charge-providing vehicle in response to the confirmation request; and
send the transfer initiation message responsive to receipt of the confirmation from the selected charge-providing vehicle.

### Claim 11

A method, comprising:
receiving, from a charge-requesting vehicle, a charge request;
determining a suggested provider pool for fulfilling the charge request, the suggested provider pool including multiple suggested charge-providing vehicles;
sending suggested provider data to the charge-requesting vehicle, the suggested provider data identifying the multiple suggested charge-providing vehicles;
receiving, from the charge-requesting vehicle, a provider selection identifying one of the multiple suggested charge-providing vehicles as a selected charge-providing vehicle;
