Abstract

A method includes determining, by a controller, a presence of an available electrical energy quantity generated from an energy generation event; comparing, by the controller, the available electrical energy quantity to an available energy capacity of a battery storage system; and responsive to determining the available electrical energy quantity exceeds the available energy capacity of the battery storage system, causing, by the controller, a transmission of at least a portion of the available energy quantity to a heat management system.

First claim

1 . A method comprising:
determining, by a controller, a presence of an available electrical energy quantity generated from an energy generation event; comparing, by the controller, the available electrical energy quantity to an available energy capacity of a battery storage system; and responsive to determining the available electrical energy quantity exceeds the available energy capacity of the battery storage system, causing, by the controller, a transmission of at least a portion of the available electrical energy quantity to a heat management system.

2 . The method of claim 1 , wherein causing the transmission of at least the portion of the available electrical energy quantity to the heat management system includes lowering a target coolant temperature of a coolant of the heat management system, wherein the target coolant temperature controls actuation of a cooling fan of the heat management system.

3 . The method of claim 2 , further comprising receiving, by the controller, an upper limit temperature threshold for the coolant and a lower limit temperature threshold for the coolant.

4 . The method of claim 3 , further comprising determining, by the controller, a coolant temperature is above the target coolant temperature and, in response, increasing the target coolant temperature toward the upper limit temperature threshold.

5 . The method of claim 4 , further comprising activating, by the controller, the cooling fan when the coolant temperature is at or near the upper limit temperature threshold.

6 . The method of claim 5 , further comprising determining, by the controller, the coolant temperature has not become at or near the upper limit temperature threshold and, in response activating, by the controller, the cooling fan upon detection of a subsequent regenerative braking event.

7 . The method of claim 3 , further comprising determining, by the controller, a coolant temperature is at or near the target coolant temperature and the available electrical energy quantity is not storable in the battery storage system and, in response, decreasing the target coolant temperature towards the lower limit temperature threshold.

8 . The method of claim 1 , further comprising detecting, by the controller, the available electrical energy quantity from a braking regeneration event.

9 . The method of claim 1 , further comprising responsive to determining the available electrical energy quantity does not exceed the available energy capacity of the battery storage system, facilitating storage, by the controller, of the available electrical energy quantity in the battery storage system.

10 . A system comprising:
a heat management system configured to couple to an engine, the heat management system including a fan and circulating a coolant, wherein the coolant absorbs heat from an engine, and wherein the fan is actuated based on a target temperature of the coolant and a sensed temperature of the coolant; and a controller structured to selectively adjust the target temperature in response to a condition of at least one of a battery or the engine to manage energy consumption by the fan.

11 . The system of claim 10 , wherein the controller is structured to utilize an upper limit temperature threshold for the coolant and a lower limit temperature threshold for the coolant in connection with the target temperature and the sensed temperature to provide actuation control of the fan.

12 . The system of claim 11 , wherein, in response to determining the sensed temperature of the coolant is above the target temperature, the controller is structured to increase the target temperature toward the upper limit temperature threshold.

13 . The system of claim 11 , wherein, in response to determining the sensed temperature has not become at or near the upper limit temperature threshold, the controller is structured to actuate the fan upon detection of a next instance of a regenerative braking event.

14 . The system of claim 11 , wherein, in response to determining that the sensed temperature is at or near the target temperature and an available electrical energy quantity is not storable in a battery storage system, the controller is structured to decrease the target temperature towards the lower limit temperature threshold.

15 . An apparatus comprising:
one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
acquire temperature data indicative of a temperature of a coolant used in a heat management system operatively coupled to an engine;
determine a presence of an available electrical energy quantity generated from an energy generation event;
compare the available electrical energy quantity to an available energy capacity of a battery storage system; and
in response to the comparison, manage a target temperature of the coolant to control activation of a fan in the heat management system and manage energy consumption by the fan.

16 . The apparatus of claim 15 , wherein the one or more memory devices are further configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to detect the available electrical energy quantity from a braking regeneration event.

17 . The apparatus of claim 15 , wherein the one or more memory devices are further configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
determine the available electrical energy quantity does not exceed the available energy capacity of the battery storage system; and in response, facilitate storage of the available electrical energy quantity in the battery storage system.

18 . The apparatus of claim 15 , wherein the one or more memory devices are further configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to utilize an upper limit temperature threshold for the coolant and a lower limit temperature threshold for the coolant in connection with the target temperature and the temperature of the coolant to provide actuation control of the fan.

19 . The apparatus of claim 18 , wherein, in response to determining the temperature of the coolant is above the target temperature, the one or more memory devices are further configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to increase the target temperature toward the upper limit temperature threshold.

20 . The apparatus of claim 18 , wherein, in response to determining the temperature of the coolant has not become at or near the upper limit temperature threshold, the one or more memory devices are further configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to actuate the fan upon a detection of a next instance of a regenerative braking event.
