Abstract

Claims (37)

1 . An actuated valveless architecture system for regulating temperature in a vehicle having a battery system and a drive system, the actuated valveless architecture system comprising:

a first bi-directional control pump;

a second bi-directional control pump;

a plurality of check valves fluidically coupled with at least one of the first bi-directional control pump and the second bi-directional control pump;

a radiator; and

a chiller,

wherein the plurality of check valves, the first bi-directional control pump, and the second bi-directional control pump are configured to define a battery loop configured to regulate temperature of the battery system and a drivetrain loop configured to regulate temperature of the drive system,

wherein the plurality of check valves comprises a first check valve, a second check valve, a third check valve, and a fourth check valve, and

wherein the first check valve is configured to prevent coolant backflow from the radiator to the first bi-directional control pump.

2 . The actuated valveless architecture system of claim 1 , wherein each of the plurality of check valves is a passive valve.

3 . The actuated valveless architecture system of claim 1 , wherein the first bi-directional control pump and the second bi-directional control pump are configured to be independently controlled and to alternate between an off state, a first direction, and a second direction opposite the first direction.

4 . The actuated valveless architecture system of claim 1 , wherein the battery loop includes the chiller.

5 . The actuated valveless architecture system of claim 1 , wherein the drivetrain loop includes the radiator.

6 . The actuated valveless architecture system of claim 1 , wherein the first bi-directional control pump and the second bi-directional control pump are configured to direct coolant flow selectively through the chiller and the radiator.

7 . The actuated valveless architecture system of claim 1 , further comprising a positive temperature coefficient (PTC) heater, wherein the battery loop includes the PTC heater.

8 . The actuated valveless architecture system of claim 1 , wherein the second check valve is configured to prevent coolant flow from the first bi-directional control pump and divert coolant through the first check valve toward the radiator.

9 . The actuated valveless architecture system of claim 8 , wherein the third check valve is configured to prevent coolant backflow from the chiller toward the second bi-directional control pump.

10 . The actuated valveless architecture system of claim 9 , wherein the fourth check valve is configured to prevent coolant flow from the second bi-directional control pump and divert coolant through the third check valve toward the chiller.

11 . The actuated valveless architecture system of claim 1 , wherein the first bi-directional control pump and the second bi-directional control pump are configured, via one or more check valves of the plurality of check valves, to restrict flow through the drive system to one-way flow.

12 . The actuated valveless architecture system of claim 1 , wherein the first bi-directional control pump and the second bi-directional control pump are configured to be controlled via a control system having a processor operatively coupled to a memory device.

13 . The actuated valveless architecture system of claim 12 , wherein the control system is configured to employ artificial intelligence (AI) to monitor and control one or both of the bi-directional control pump and the second bi-directional control pump.

14 . An actuated valveless architecture system for regulating temperature in a vehicle having a battery system and a drive system, the actuated valveless architecture system comprising:

a first bi-directional control pump;

a second bi-directional control pump;

a radiator;

a chiller,

wherein each of the first bi-directional control pump and the second bi-directional control pump is bidirectional, and

wherein each of the first bi-directional control pump and the second bi-directional control pump is configured to be independently controlled and to alternate between an off state, a first direction, and a second direction opposite the first direction; and

a plurality of check valves fluidically coupled with at least one of the first bi-directional control pump and the second bi-directional control pump,

wherein the plurality of check valves, the first bi-directional control pump, and the second bi-directional control pump are configured to define a battery loop configured to regulate temperature of the battery system and a drivetrain loop configured to regulate temperature of the drive system,

wherein the plurality of check valves comprises a first check valve, a second check valve, a third check valve, and a fourth check valve, and

wherein the first check valve is configured to prevent coolant backflow from the radiator to the first bi-directional control pump.

15 . The actuated valveless architecture system of claim 14 , wherein the first bi-directional control pump and the second bi-directional control pump are configured to direct coolant flow selectively through the chiller and the radiator.

16 . The actuated valveless architecture system of claim 14 , wherein the first bi-directional control pump and the second bi-directional control pump are configured, via one or more check valves of the plurality of check valves, to restrict flow through the drive system to one-way flow.

17 . The actuated valveless architecture system of claim 14 , wherein the second check valve is configured to prevent coolant flow from the first bi-directional control pump and divert coolant through the first check valve toward the radiator.

18 . The actuated valveless architecture system of claim 17 , wherein the third check valve is configured to prevent coolant backflow from the chiller toward the second bi-directional control pump.

19 . The actuated valveless architecture system of claim 18 , wherein the fourth check valve is configured to prevent coolant flow from the second bi-directional control pump and divert coolant through the third check valve toward the chiller.
