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 »

Livingston Products develops battery self-cooling system

Illinois-based Livingston Products has developed a new liquid cooling pump system that uses the heat from a battery to propel a proprietary cooling fluid through a system of tubes. The Transthermal Heat Bridge, the subject of more than ten individual patents pending, can be scaled to fit almost any battery configuration, according to the company,… Read more »

VW: e-Golf battery pack doesn’t need a liquid cooling system

Does an EV battery pack need a liquid cooling system? Automakers have different opinions. The Tesla Roadster and Model S have ‘em, the Nissan LEAF does not. Volkswagen initially designed its e-Golf with a liquid-cooled battery, but the production e-Golf, which is now on sale in Germany, and will arrive in selected US markets during… Read more »

ION Storage Systems achieves milestone with its anodeless solid-state battery

ION Storage Systems, a Maryland-based manufacturer of solid-state batteries, has announced that its anodeless and compressionless SSB achieved a key threshold with its first market deployment with the US military. ION says its SSB successfully exceeded 125 cycles with less than 5% capacity degradation in performance, offering the potential for more than 1,000 cycles in… Read more »

Battery cell qualification for EVs: Lucid’s cell specialist discusses the complicated process

Q&A with Lucid’s Battery Cell Technical Specialist Maithri Venkat. When it comes to battery cells for EVs, one size definitely doesn’t fit all. The properties of a particular cell act as constraining factors for every aspect of a vehicle’s design—and not only for vehicle performance parameters such as range and power, but for the development… Read more »
