Abstract
Described is an actuated valveless architecture system for regulating temperature in a vehicle having a battery system and a drive system. The actuated valveless architecture system includes a first screw pump, a second screw pump, and a plurality of check valves. The plurality of check valves is fluidically coupled with at least one of the first screw pump and the second screw pump. The plurality of check valves is configured to define a battery loop to regulate temperature of the battery system and a drivetrain loop to regulate temperature of the drive system.

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 screw pump;
- a second screw pump;
- and
- a plurality of check valves fluidically coupled with at least one of the first screw pump and the second screw pump,
- wherein the plurality of check valves, the first screw pump, and the second screw 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.
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 screw pump;
- a second screw pump,
- wherein each of the first screw pump and the second screw pump is bidirectional, and
- wherein each of the first screw pump and the second screw 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 screw pump and the second screw pump,
- wherein the plurality of check valves, the first screw pump, and the second screw 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.
