BMW seeks new EV battery cooling solutions

BMW is seeking new solutions for EV battery cooling that can provide improved cooling capacity during fast charging as well as a reduction in noise and vibration emissions. BMW will consider both early-stage and mature solutions, and will work to evaluate and develop solutions that meet its criteria. BMW’s key criteria for solutions include an… Read more »

XING Mobility’s electric supercar uses novel battery cooling system

Taipei-based electric powertrain startup XING Mobility has announced a 1,341 hp rally-inspired supercar that’s not afraid to leave the roadway. Miss R has 4 independent 350 V motors and 4-wheel torque vectoring, and XING says she will be able to reach 100 km/h in 1.8 seconds. In response to the inevitable comparison to the new… Read more »

Johnson Controls and Fraunhofer collaborate on new battery cooling systems

Johnson Controls and the Fraunhofer-Gesellschaft, one of Europe’s biggest organizations for applied research, have signed an agreement to develop next-generation cooling systems for vehicle batteries. The collaboration will focus on technologies and thermal management strategies for lithium-ion battery packs. Currently, systems with fans, compressors or pumps use energy to pull heat out of a battery…. Read more »

Accelerate Testing And Verification Of EV Li-Ion Battery Pack Cooling Systems With Virtual Prototyping

This presentation will demonstrate an active cooling system for a Li-ion battery pack that allows the user to specify the coolant type and its mixture ratio. The introductory system example consists of a hydraulic pump, fluid cooling plate, pipelines, thermostat, fluid-air heat exchanger, and a small coolant reservoir, to permit initial investigations and set the… Read more »

Accelerate Testing And Verification Of EV Li-Ion Battery Pack Cooling Systems With Virtual Prototyping

This presentation will demonstrate an active cooling system for a Li-ion battery pack that allows the user to specify the coolant type and its mixture ratio. The introductory system example consists of a hydraulic pump, fluid cooling plate, pipelines, thermostat, fluid-air heat exchanger, and a small coolant reservoir, to permit initial investigations and set the stage for more advanced designs. The pump maintains Ethylene-Glycol coolant circulation through the thermohydraulic circuit and the self-heating battery pack, characterized from cell measurement data, is scalable with respect to the number of cells, initial temperature and SoC, and age profiles. Virtual prototyping is invaluable for testing and verifying features and functionality early in the design phase. Doing this through pure hardware prototyping is impracticable since the specification of new topologies is done very early in the concept phase when the architecture details of the entire system may be unknown. The virtual prototype therefore takes the role of an evolving executable functional spec.

Rivian says its battery pack has the highest volumetric energy density in the world, thanks to its cooling strategy

Rivian has been generating a lot of headlines since the November 2018 reveal of its prototype pickup and SUV. The company has scored substantial investments, including $700 million from a group of investors led by Amazon and another $500 million from Ford. That cash was accompanied by a history-making order of 100,000 electric delivery vans… Read more »

M&I Materials’ new dielectric fluids for battery and charger immersion cooling

UK-based M&I Materials has developed a new range of biodegradable dielectric fluids, MIVOLT, to provide immersion cooling for EV batteries and charging points. As non-conductive fluids, MIVOLT fluids can come into direct contact with electronic components, which M&I says is a more effective method of heat removal and a lighter-weight option than designs that rely… Read more »

The Goldilocks zone: Calienté explains that battery pack heating is just as important as cooling

In the eyes of an EV driver, the success of the battery is measured in a completely binary way: does the battery last the life of the vehicle, or not? In fact, the best praise you can give any battery – whether in your laptop, phone, or EV – is not to have to think… Read more »

Simulation of battery pack cooling systems: measure twice, cut once

The experts at Mentor Graphics walk us through the simulation and analysis of a battery pack cooling system. In the business of battery pack design, one of the main considerations is cooling. The pack must have a uniform and stable temperature for the batteries to perform adequately during worst-case conditions. Even within a single cell,… Read more »
