In one embodiment, a method includes, receiving, at a vehicle-side controller via a communication channel, a request from the peripheral device to modify the electrical power delivery to the peripheral device. The method includes, in response to identifying that the request is for an increase to the electrical power delivery, determining an electrical loading of the vehicle. The method also includes communicating a message over the communication channel to the peripheral device that causes the peripheral device to manage the electrical power delivery according to whether the electrical loading satisfies a loading threshold of the vehicle. ## Claims ### Claim 1 A vehicle-side controller for managing electrical power delivery to a peripheral device in a vehicle, comprising: one or more processors; a memory communicably coupled to the one or more processors and storing: an evaluation module including instructions that when executed by the one or more processors cause the one or more processors to: receive, via a communication channel, a request from the peripheral device to modify the electrical power delivery to the peripheral device, and in response to identifying that the request is for an increase to the electrical power delivery, determine an electrical loading of the vehicle; and a communication module including instructions that when executed by the one or more processors cause the one or more processors to communicate a message over the communication channel to the peripheral device that causes the peripheral device to manage the electrical power delivery according to whether the electrical loading satisfies a loading threshold of the vehicle. ### Claim 2 (depends on 1) The vehicle-side controller of claim 1, wherein the evaluation module includes instructions to analyze observations of a voltage and a current of a power delivery system of the vehicle that is connected to the peripheral device, and wherein the loading threshold is based at least in part on an electrical power limit of the power delivery system. ### Claim 3 (depends on 1) The vehicle-side controller of claim 1, wherein the evaluation module includes instructions to determine when an engine of the vehicle is in an off state, and wherein the loading threshold is based at least in part on the engine being in the off state. ### Claim 4 (depends on 1) The vehicle-side controller of claim 1, wherein the communication module includes instructions to communicate the message including instructions to generate the message to specify at least one of a wait time for requesting the increase again, a hold command to wait until further notified to request the increase again, a partial acceptance that a percentage of the increase is available, and a full acceptance of the increase is available. ### Claim 5 (depends on 1) The vehicle-side controller of claim 1, wherein the communication module includes instructions to communicate the message to manage the electrical power delivery including instructions to cause the peripheral device to respond by one or more maintaining a present electrical loading from a power delivery system of the vehicle, and executing a percentage of the increase from the power delivery system. ### Claim 6 (depends on 1) The vehicle-side controller of claim 1, wherein the communication module further includes instructions to, in response to identifying that the request is for a decrease to the electrical power delivery, communicate the message to initiate the decrease to the peripheral device that reduces the electrical power delivery at a ramp-down rate. ### Claim 7 (depends on 1) The vehicle-side controller of claim 1, wherein the communication channel includes at least one of a wired medium, a wireless medium and a fiber-optic medium. ### Claim 8 A method for managing electrical power delivery to a peripheral device in a vehicle from a vehicle-side controller, comprising: receiving, at the vehicle-side controller via a communication channel, a request from the peripheral device to modify the electrical power delivery to the peripheral device; in response to identifying that the request is for an increase to the electrical power delivery, determining an electrical loading of the vehicle; and communicating a message over the communication channel to the peripheral device that causes the peripheral device to manage the electrical power delivery according to whether the electrical loading satisfies a loading threshold of the vehicle. ### Claim 9 (depends on 8) The method of claim 8, wherein evaluating the electrical loading includes analyzing observations of a voltage and a current of a power delivery system of the vehicle that is connected to the peripheral device, and wherein the loading threshold is based at least in part on an electrical power limit of the power delivery system. ### Claim 10 (depends on 8) The method of claim 8, wherein evaluating the electrical loading includes determining when an engine of the vehicle is in an off state, and wherein the loading threshold is based at least in part on the engine being in the off state. ### Claim 11 (depends on 8) The method of claim 8, wherein communicating the message includes generating the message to specify at least one of a wait time for requesting the increase again, a hold command to wait until further notified to request the increase again, a partial acceptance that a percentage of the increase is available, and a full acceptance of the increase is available. ### Claim 12 (depends on 8) The method of claim 8, wherein communicating the message to manage the electrical power delivery includes causing the peripheral device to respond by one or more maintaining a present electrical loading from a power delivery system of the vehicle and executing a percentage of the increase from the power delivery system. ### Claim 13 (depends on 8) The method of claim 8, further comprising: in response to identifying that the request is for a decrease to the electrical power delivery, communicating the message to initiate the decrease to the peripheral device that reduces the electrical power delivery at a ramp-down rate. ### Claim 14 (depends on 8) The method of claim 8, wherein the communication channel includes at least one of a wired medium, a wireless medium and a fiber-optic medium. ### Claim 15 A method for managing electrical power delivery to a peripheral device connected with a power delivery system in a vehicle, comprising: determining power attributes for operating the peripheral device and current attributes of electrical power being delivered to the peripheral device over the power delivery system;
