The conduit system may provide a path for coolant to enter and exit the pack and includes a conduit. The sensor may measure conditions of the pack and conduit system. The emitter may be arranged with the conduit to form a peristaltic pump. The control system may activate the pump based on sensor signals to adjust a conduit portion to influence a flow rate of the coolant flowing therethrough. The emitter may be an electromagnet to output a magnetic field. The emitter may be a voltage emitter or electric field emitter. The sensor may measure a flow rate of at least a portion of the conduit system or a temperature of the pack. ## Claims ### Claim 1 A traction battery thermal management system comprising: a traction battery pack; a conduit system providing a path for coolant to enter and exit the traction battery pack and including a conduit; a sensor to measure conditions of the traction battery pack and the conduit system; a peristaltic pump having an emitter comprised of at least one electromagnet arranged with the conduit; and a control system to activate the peristaltic pump based on signals from the sensor to adjust at least one portion of the conduit to influence a flow rate of the coolant flowing therethrough. ### Claim 2 (depends on 1) The traction battery thermal management system of claim 1, wherein the emitter comprises an electromagnet to output a magnetic field. ### Claim 3 (depends on 1) The traction battery thermal management system of claim 1, wherein the emitter comprises a voltage emitter or electric field emitter. ### Claim 4 (depends on 1) The traction battery thermal management system of claim 1, wherein the sensor measures a flow rate of at least one portion a of the conduit or a temperature of the pack. ### Claim 5 (depends on 1) The traction battery thermal management system of claim 1, wherein the control system is programmed to selectively activate the emitter to output a magnetic field or an electric field to promote a flow of coolant within at least one portion of the conduit located adjacent to battery cells of the traction battery pack having a temperature exceeding a threshold value. ### Claim 6 (depends on 1) The traction battery thermal management system of claim 1, wherein the control system is programmed to selectively activate the emitter to output a magnetic field or an electric field to promote a flow of coolant within at least one portion of the conduit having a flow rate below a threshold value. ### Claim 7 A vehicle traction battery thermal management system comprising: a traction battery pack; a conduit system including a conduit forming a coolant path, the conduit fluidly connected to the traction battery pack via an entry and exit such that the coolant path flows through the traction battery pack; a peristaltic pump cooperable with the conduit and having an emitter arranged with the conduit at selective portions of the conduit, the emitter being configured to alter a flow rate of the coolant through the conduit; and a control system configured to activate the peristaltic pump responsive to signals from a sensor configured to detect conditions of the traction battery pack and the conduit system, and adjust the flow rate through the selective portions. ### Claim 8 (depends on 7) The vehicle traction battery thermal management system of claim 7 wherein the emitter comprises an electromagnet to output a magnetic field to promote coolant flow through the conduit. ### Claim 9 (depends on 7) The vehicle traction battery thermal management system of claim 7 wherein the emitter comprises a voltage emitter or electric field emitter to control coolant flow through the conduit. ### Claim 10 (depends on 7) The vehicle traction battery thermal management system of claim 7, wherein the control system is programmed to selectively activate the emitter of the peristaltic pump to output a magnetic field or an electric field to promote a flow of coolant within a portion of the conduit located adjacent to battery cells of the traction battery pack having a temperature exceeding a threshold value. ### Claim 11 (depends on 7) The vehicle traction battery thermal management system of claim 7, wherein the selective portions include a portion located adjacent to the battery cells of the traction battery pack.
