A person in my extended family owns an insurance brokerage firm. I asked him last night if insurance companies are evaluating fire risk if an EV is parked inside an insured home garage or within home structure like a lean-to. He said absolutely they are and EV owners should expect to see home insurance increases in the coming years because of this risk. He said insurance companies understand an ICE car parked within a home structure poses fire risk and that is already backed into premiums (the risk considered low), but with EVs, the concern is the extreme heat, intensity, prolonged burn, and more toxic vapors of an EV battery fire.
I also asked about charging stations in the home and he said there isn't much chatter about that and if there was a fire caused by the charging station, they'd likely go after the installer in most cases, unless of course the home owner installed one themselves without a permit (most municipalities require some type of permit for install). If that's the case, the home owner may be out of luck with coverage.

Why Teslas Won’t Charge in Freezing Temps
1/16/24 Tesla owners in the Chicago area are finding themselves in a huge pickle this week with temps dipping into the negative double-digits. As drivers seek fast charging through Tesla’s Supercharger network, the cold weather is so severe it’s preventing vehicles from accepting a charge. EVs don’t take well to charging in subzero temps because their batteries need to be at optimal operational warmth. In most seasons, this isn’t an issue. But in hypercold conditions, the battery must be preconditioned. According to Tesla’s Model S owner’s manual, “Tesla recommends activating climate settings at least 30-45 minutes before departure (see Operating Climate Controls). Preconditioning times depend on outside temperature and other factors. The mobile app will notify you once your vehicle has reached the desired preconditioning temperature.” It’s possible the stacks of Tesla drivers stranded at Supercharger stations didn’t precondition their batteries. At this time, Tesla cars don’t have a manual preconditioning procedure. So, at a certain point, a dead Tesla stuck outside in subzero weather simply won’t accept a charge. They’ll have to be towed somewhere warmer, like an indoor setting with a charger. That would be the indoor facility heated by..... wait for it...... wait for it...... Yes Fossil fuels https://www.motorbiscuit.com/why-tes...reezing-temps/ Kind of a shame to pick on Tesla on this one as this will effect any EV or any thing with a battery. My Kubota diesel was pretty dam unhappy at 14deg this morning but it started. Now here is the kicker. When a cold snap hits and when green idiots and stupid politicians do permanent damage to our power grid, Do you think they are going to let you have their precious electrons for your car when people are freezing to death? If you answered yes, you are a moron and deserve what ever happens to you. |

I also have no sympathy for the morons that don’t precondition the interiors of their Teslas while complaining about how hard it is to open their door handles. |

MN is not that different from IL weather wise. I expect my appliances to work cold or not. Maybe tesla owen's can contact coustemer services to get this problem resolved 😉

Assessing the value of electric vehicle managed charging: a review of methodologies and results Unmanaged EV charging can stress existing grid infrastructure, possibly leading to operational, reliability, and planning challenges both at the Managed charging can support power system planning and operations during normal and extreme conditions, benefitting EV owners and other electricity consumers. However, the costs of enabling these services must be weighed against the benefits they provide. We summarize the benefits of managed EV charging, provide an overview of the landscape of existing implementations and costs of managed charging in the United States, critically review the state of the art of methodologies in analysis/modeling studies, and quantify the cost and benefits of managed charging as reported in the reviewed studies. Finally, we distill several key insights outlining the factors affecting the value of managed EV charging and identify critical gaps and remaining challenges to fully realize effective EV-grid integration. Active managed charging programs provide utilities, or a market aggregator working with charging networks, with the capability to determine and/or control charging time, scale, and location, “in order to achieve a variety of outcomes, such as managing peaks, absorbing excess renewable generation or supplying some ancillary services to a structured market.” These programs rely on a reliable two-way flow of information that includes 1) a transport layer which relies on a communication signal via Wi-Fi, cellular, vehicle telematics, etc. to send the charging instructions and 2) a messaging protocol or standard that can help the device understand and execute the instructions. https://pubs.rsc.org/en/content/arti.../ee/d1ee02206g You EV guys are so "F"ed Better get that Honda generator in your trunk. |

Managed EV Charging
Managed EV charging is an adaptive means of charging EVs which considers both vehicle energy needs and control objectives, typically designed to provide grid support or mitigate the impacts of EV charging. The benefits of managed charging range from reducing electrical equipment upgrades, maximizing the value of local generation, and reducing the cost of grid energy. Managed charging also ensures that fleet vehicles are properly powered when needed, while reducing unnecessary burden on the building infrastructure and supporting a more reliable and resilient grid. https://www.energy.gov/femp/managed-...mobile-storage That is government speak for we will allow you to charge your EV's if we don't need the electricity elsewhere. If you have a issue with that: Call the US Department of Energy. |

Why you should not charge a lithium battery below 32 degrees
If you have a Lithium (LiFePO4) battery, there are some things to consider when charging under extreme temperature conditions. Lithium battery manufacturers often state an operational temperature range of -30°C to +80°C / -22°F to +176°F and an optimal temperature range of -10°C to +50°C / 14°F to 122°F (this varies depending on brand and model, consult your manufacturer). This is often misconstrued as a safe temperature range for both charging and discharging, this is not the case. The operational temperature range is referring to discharging the battery only. Charging a Lithium battery in ambient temperatures below 0°C / 32°F must be avoided. The reason for this is it may potentially damage the battery and / or reduce its lifespan. The optimum ambient temperature for charging a Lithium battery is +5°C to +45°C / 41°F to 113°F. When attempting to charge a Lithium battery below 0°C / 32°F a chemical reaction referred to as “Lithium Plating” occurs. Lithium plating is caused by the charge current forcing the lithium ions to move at a faster reaction rate and accumulate on the surface of the anode. When this chemical reaction occurs, the internal resistance of the battery increases and reduces the rate of chemical metabolism. This chemical reaction causes a permanent reduction of the battery’s capacity and will continue to reduce its capacity each time this reaction occurs. If you plan on using a Lithium battery in a location that may drop below 0°C / 32°F, you must be cautious as to when you attempt to charge the battery. Simply waiting for the temperature to raise during the day is a simple solution. Having the batteries mounted in a location that will have a higher ambient temperature than outside temperature is also advisable. https://www.redarcelectronics.com/us...ow-32-degrees/ |

Better not own a diesel truck either... negative double digits is gelled diesel fuel. Had to give an industry acquaintance a ride back from a ski resort because his truck gelled up in the parking lot on a really cold day last season...
