1. A thermal management system for an energy storage system included in a hybrid electric system that comprises a power electronic converter, the energy storage system comprising:
an energy storage device;
an energy storage monitoring system including circuitry dedicated and configured to monitor a temperature of the energy storage device, the energy storage monitoring system including an energy storage controller,
wherein the thermal management system comprises:
a thermal management conditioning loop;
a pump configured to circulate a thermal management fluid through the thermal management conditioning loop;
an in-line heater;
first transfer hardware that transfers heat between the thermal management fluid and the energy storage device; and
second heat transfer hardware that transfers heat between the thermal management fluid and the power electronic converter,
wherein the in-line heater, the first heat transfer hardware, the second heat transfer hardware, and the energy storage device are in thermal communication with the thermal management fluid via the thermal management conditioning loop,
wherein the in-line heater is located on a bypass line of the thermal management conditioning loop that bypasses the second heat transfer hardware, and
wherein the energy storage controller of the energy storage monitoring system is configured to confirm that a temperature of the thermal management fluid and/or a temperature of the energy storage device is below an upper safety limit, between a lower control limit and an upper control limit, or both, and in response, to send an enable heater request indicating the in-line heater is to turn on.
