System and method for controlling battery preconditioning in a work machine

A control system within a work machine, comprising:

• a battery configured to power the work machine, the battery having a state of charge (SoC) and a battery cell temperature;
• a battery thermal management system (BTMS) configured to regulate the battery cell temperature using one of an active thermal mode and a passive thermal mode;
• an operator interface;
• and
• an electronic controller configured to:
• calculate an expected decrease in the SoC caused by having the BTMS adjust the battery cell temperature to a preconditioning temperature under current operating conditions for the work machine,
• based, at least in part, on the expected decrease in the SoC, determine a threshold SoC at which to communicate a notification relating to preconditioning the battery,
• after the SoC equals the threshold SoC, communicate the notification via the operator interface,
• receive a response to the notification via the operator interface, the response comprising a request for a Fast Charge or a refusal of the Fast Charge, and
• based on the response, instruct the BTMS to adjust the battery cell temperature using one of the active thermal mode and the passive thermal mode.

A computer-implemented method, comprising:

• receiving, by an electronic controller, data relating to current operating conditions of a work machine powered by a battery, the current operating conditions including ambient temperature and a battery cell temperature of the battery;
• calculating, by the electronic controller, an expected decrease in a state of charge (SoC) of the battery caused by having a battery thermal management system (BTMS) adjust the battery cell temperature to a preconditioning temperature under the current operating conditions;
• based, at least in part, on the expected decrease in the SoC, determining a threshold SoC at which to provide a notification relating to preconditioning the battery;
• comparing the SoC to the threshold SoC;
• after the SoC equals the threshold SoC, communicating the notification via an operator interface;
• receiving a response relating to the notification via the operator interface;
• and
• instructing the BTMS to regulate the battery cell temperature in response to the response.
