1. A method, comprising: transferring heat from a battery cell to a heat spreader;conducting the heat from the heat spreader into a coolant channel; anddissipating the heat into a heat transfer medium communicated vertically inside the coolant channel to thermally manage the battery cell,wherein the coolant channel is connected to a supply line and a return line that are both positioned axially between a first battery module and a second battery module that each include a plurality of battery cells. 2. The method as recited in claim 1, comprising sensing a temperature condition of the battery cell. 3. The method as recited in claim 2, comprising heating the battery cell in response to the temperature condition indicating a cold ambient condition. 4. The method as recited in claim 3, wherein heating the battery cell includes actuating a film heater. 5. The method as recited in claim 2, comprising commanding the dissipating step in response to the temperature condition indicating a hot ambient condition. 6. The method as recited in claim 1, comprising heating the battery cell with a film heater if a temperature of the battery cells is below a threshold temperature. 7. The method as recited in claim 6, wherein the film heater is in direct contact with a surface of the battery cell. 8. The method as recited in claim 7, wherein the heat spreader is in contact with a different surface of the battery cell. 9. The method as recited in claim 6, wherein the film heater is in direct contact with a bottom surface of the battery cell and the heat spreader is in direct contact with a side surface of the battery cell. 10. The method as recited in claim 1, wherein the coolant channel is attached to the heat spreader. 11. The method as recited in claim 1, comprising cooling the heat transfer medium prior to communicating the heat transfer medium to the coolant channel. 12. The method as recited in claim 1, comprising conducting the heat from the heat spreader into a second coolant channel. 13. The method as recited in claim 12, wherein the coolant channel and the second coolant channel are mounted to opposing edges of the heat spreader. 14. The method as recited in claim 1, comprising: communicating the heat transfer medium from a supply manifold into the coolant channel; andcommunicating the heat transfer medium from the coolant channel into a return manifold. 15. The method as recited in claim 14, wherein the supply manifold and the return manifold are mounted at different locations of the coolant channel. 16. The method as recited in claim 1, comprising communicating the heat transfer medium across at least one augmentation feature inside the coolant channel. 17. The method as recited in claim 1, wherein the heat transfer medium is communicated upwardly from a bottom toward a top of the coolant channel or is communicated downwardly from the top toward the bottom of the coolant channel. 18. The method as recited in claim 1, wherein the coolant channel is attached to an outermost edge of the heat spreader, a supply manifold is attached to one of a top and a bottom of the coolant channel, and a return manifold is attached to the other of the top and the bottom of the coolant channel.
