And with a smart thermal management system that Bosch introduced in 2015, it claimed 25 percent better range in wintry urban situations. Cookies help us deliver our Services. From an efficiency standpoint, how effective is it at lowering the range reduction compared to normal heating? The charging standard will still be CHAdeMO, even in Europe, which may be a strategic mistake by Nissan. A chiller and condenser serve the functions of an evaporator and condenser, while in between there’s a thermal expansion valve and at the other end of the system, an electric drive compressor. This charge rate may be trimmed slightly, to just under 100 kW, on the release model. Sign up for our free daily newsletter or weekly newsletter to never miss a story. Heat pumps aid efficiency because they move heat rather than generate it. Anyone following EVs for a while is aware of the thermal management issues that have beset the 40 kWh Nissan LEAF as well as previous generations of the car, and that have disappointed a great many owners of the vehicle as a result.

Really, the Leaf's range is so short that you're not normally driving in the cold long enough to meaningfully impact range. All Rights Reserved. Even with this, some charge power throttling does still occur to avoid excessive battery pack heating. What do you think? I thought the heatpump did not have resistance heat as a backup like heatpumps in houses do. ), or, For LG Chem to provide a cell chemistry with magically low internal resistance (unlikely), or, For the pack voltage to move from the current 360 volts up to 600 or 800 volts (very unlikely), or, For Nissan to fit the LEAF with an industrial-strength air cooling system (hopefully). Thanks to Arnis Tarassu for pointing that out. ] A report on the upcoming 60 kWh Nissan LEAF from respected German news site Electrive.net suggests that it will still lack liquid cooling of the battery. I’m in southeast Alaska. Not all EVs have it. Also, I see condensation brought up a lot. Heating especially gets skipped over in the EPA’s driving-cycle calculations for EVs. Or are we going to see #Rapidgate all over again? To that, there’s some cost-benefit analysis to be done. Really, the Leaf's range is so short that you're not normally driving in the cold long enough to meaningfully impact range. http://www.mynissanleaf.com/viewtopic.php?t=23617.

Ab Mitte 2019 bringt Nissan das Sondermodell Leaf Zero e+ mit 160-kW-Elektromotor (217 PS) und 62-kWh-Batterie. For electric cars that are truly intended for use outside of California—and ready for next year’s deep freeze—the tech is becoming harder to ignore. Models with heat pumps typically use a reversible setup to transfer thermal energy out of the cabin during hot weather (functioning as an air-conditioning compressor), and to bring thermal energy from power components or outside into the cabin in cold weather. The 60 kWh LEAF will be available on sale in Europe from May 2019. The only conceivable ways around having a well designed active liquid cooling system are either: The report author, Peter Schwierz, suggests that the 60 kWh LEAF, which Nissan originally planned to be unveiled at the recent LA Auto Show, will now be unveiled at the Consumer Electronics Show in early January 2019, just over a month from now.

Dr. Maximilian Holland Max is an anthropologist, social theorist and international political economist, trying to ask questions and encourage critical thinking about social and environmental justice, sustainability and the human condition. What makes it different is that it’s a neatly packaged, modular system that “can be adapted to future vehicle architectures,” Mahle says, and a unified alternative to what the supplier originally teased as a “holistic thermal management” system in 2017. As another poster shared with the graph, it gets to a point where the air is too cold for the heat pump to be effective. We also know that the battery cell supply will change from Nissan’s partially owned subsidiary AESC to newer-chemistry LG Chem cells. Climate control systems still need the toaster bits and the traditional air conditioning operation for quick heat or cooling when you get in the car, but they help keep things comfortable over long commutes or road trips. The current LEAF … Thanks so much for the detailed reply! Here, it gets sub-40 for a month or two so I need to run my S's heater for maybe 10 minutes total in the morning. I'm looking at the 2018s and I feel the s would do the trick. The 2019 62 kWh Nissan LEAF brings some positive updates to the vehicle, first launched in 2010 and still clinging onto the global top spot in cumulative EV sales. The advertising standards agency in the UK even ruled against Nissan’s original marketing of the LEAF, due to Nissan not clearly disclosing the thermal management issues and related charging performance throttling. This past winter’s deep freeze and its record-low temperatures exposed a reality that anyone thinking about an electric car has to come to terms with: Cold winter weather can cut the effective driving range of some electric vehicles by 40 percent or more. I'm deciding between the S and the SV and I've seen the heat pump mentioned quite a few times. Tesla models don’t use a heat pump as part of the climate control system but do use waste heat from the motor and power electronics to help warm the battery. Spending on a heat pump will save many kwh of energy, and that translates directly to more miles of range (or less battery capacity needed)—meaning you recover more miles per minute you’re fast charging. Did you get the SV or the SL to get it in yours? Is that issue the same regardless of whether or not there is a heat pump or is it alleviated by the heat pump? Ohio here. h battery pack and up-to-240-mi/384 km rated range. Find Max's book on social theory, follow Max on twitter @Dr_Maximilian and at MaximilianHolland.com, or contact him via LinkedIn. All versions of the BMW i3 EV have offered it, and the Jaguar I-Pace and Audi E-tron have a heat-pump system.
