Immersed liquid-cooled battery system that provides higher cooling efficiency and simplifies battery manufacturing compared to conventional liquid cooling methods. The system involves enclosing multiple battery cells in a sealed box and immersing them directly in a cooling medium.
The battery pack heating is also provided by the coolant, while heat sources and heating strategies can widely vary from application (e.g. waste heat recovery from other powertrain systems or direct heating of the battery coolant through PTC heater for example). Coolant cooling is an efficient system for several reasons:
It is the simplest approach to battery cooling. Using conduction through battery and vehicle mounts, as well as natural convection within the battery pack, it transfers the heat generated inside the pack to the environment with no, or limited (e.g. ducting), additional hardware.
A liquid or air cooling system must manage this elevated heat without compromising safety or performance. Fast charging also demands cooling systems capable of rapidly dissipating generated heat to prevent overheating, a factor that could undermine battery longevity and safety.
Xiaoyu Na et al. [61, 62] developed a simplified calculation model for reverse-ventilated battery pack cooling and shown that this technique efficiently reduces the maximum interior battery pack temperature while also reducing the local range of temperatures. However, air cooling cannot effectively manage the temperature in hot weather.

Battery conditioning (heating) seems to be reserved for very cold weather. I've seen small bits of it in the infotainment energy use display during a morning start when it's been near or just below freezing much of the night. Heat for the cabin and defrost is a much bigger energy user.
Lauren E. Chevrolet Customer Care The question was : If the Bolt is parked UNPLUGGED in very cold conditions, will the battery thermal protection work, and how much battery capacity will the thermal protection use? It sounds as if you are saying that YES, if parked unplugged in very cold conditions, the battery thermal protection will activate.
So to me it must use the "battery conditioning" while unplugged if cold enough. Write your reply... The manual recommends plugging in below 32F and over 32C when it's parked, to keep the battery conditioned and promote longevity.
In addition, the Bolt EV will not warm the battery as aggressively when it is turned off, even if it is plugged in and charging. To properly warm the battery during harsh winter conditions, it might be necessary to actually turn the car on while it is still plugged in.
That could be a problem Amber. The Bolt has thermal management but gives no indication of battery temperature. How will we know if the system is functioning properly? A temperature gauge should be standard on any EV. But again, someone will figure out how to get that data from the can bus and give it to us in a spy app. DNAinaGoodWay said:

It's important to remember that even though the vehicle can handle being unplugged in below zero temperatures, it's generally not a good idea to do that. Whenever possible, keep the vehicle plugged in. Keeps everything in tip-top shape and helps you avoid any potential issues.
Abstract: Battery thermal management is becoming more and more important with the rapid development of new energy vehicles. This paper presents a novel cooling structure for cylindrical power batteries, which cools the battery with heat pipes and uses liquid cooling to dissipate heat from the heat pipes.
The system involves submerging the batteries in a non-conductive liquid, circulating the liquid to extract heat, and using an external heat exchanger to further dissipate it. This provides a closed loop immersion cooling system for the batteries. The liquid submergence and circulation prevents direct air cooling that can be less effective.
By changing the surface of cold plate system layout and the direction of the main heat dissipation coefficient of thermal conductivity optimization to more than 6 W/ (M K), Huang improved the cooling effect of the battery cooling system.
