My defroster/defogger is on for all but about one week a year and the heat pump makes a huge difference for me. The heat pump basically means winter doesn't hurt my range as soon as it hurts others, but once it gets too cold for the heat pump to work, I'm suddenly just as bad as any other leaf. HP made a big difference in moderate cold (south east USA). Ab Mitte 2019 bringt Nissan das Sondermodell Leaf Zero e+ mit 160-kW-Elektromotor (217 PS) und 62-kWh-Batterie. To that, there’s some cost-benefit analysis to be done. Do you have any regret in going with the S at all? Last month it announced what it calls the Integrated Thermal System, which the company says could recover 20 percent of the cold-weather loss. Thanks so much for the detailed reply! The 2013 Nissan Leaf was the first mass-produced vehicle in the world to offer a heat-pump-based cabin heater; that system has helped extend driving range during the winter months.

I’m in southeast Alaska. The electric Jag also is expected to deliver near its rated range in very cold weather. Ohio here. There’s another reason why many more vehicles don’t have it—especially in the U.S. A heat pump system won’t raise official range estimates significantly, if at all. Really, the Leaf's range is so short that you're not normally driving in the cold long enough to meaningfully impact range. I'm deciding between the S and the SV and I've seen the heat pump mentioned quite a few times. 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. Cookies help us deliver our Services.

I added quotations there because I feel like this is wizardry unless we are talking about something like a reverse fridge where warm air is pumped in and cooler air expelled. 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.

We have known for a while that the battery output power would increase to 149 kW (200 hp), up from the current 110 kW (147 hp).

With Tesla the one exception, perhaps, EVs that omit the heat pump in the climate system generally do so to save cost. Have a tip for CleanTechnica, want to advertise, or want to suggest a guest for our CleanTech Talk podcast?

So does the Toyota Prius Prime, and most versions of the Volkswagen e-Golf.

I can definitely tell you when resistance heat kicks in as it has a different smell to the air; usually the car only uses it when it’s freezing or below and mostly to warm up from a cold start. And if you do need to hypermile your car on long drives in the winter, you sure picked the wrong car, heater or no! The gains are significant, though. The 60 kWh LEAF will be available on sale in Europe from May 2019. The supplier Mahle is one of several companies looking at the cold-weather problem comprehensively. Notably, with higher power comes higher heat generation. That system is one of several developed by suppliers around heat-pump technology and other thermal strategies, aiming to reduce the load on resistive heating. I agree to receive emails from Green Car Reports.

Or are there other efficiency issues you are getting at compared to other cars in its class? by Dr. Maximilian Holland, December 5th, 2018 by Dr. Maximilian Holland. All versions of the BMW i3 EV have offered it, and the Jaguar I-Pace and Audi E-tron have a heat-pump system. By using our Services or clicking I agree, you agree to our use of cookies.

The Mahle ITS incorporates several different components into a single system that can help with heating and cooling, for both the cabin and power systems. which may be a strategic mistake by Nissan, CleanTechnica member, supporter, or ambassador, Tesla Cofounder J.B.

Thanks.

Please let us know what you think in the comments. 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. I understand that I can unsubscribe at any time. This is the challenge that a battery cooling system must overcome.

Really, the Leaf's range is so short that you're not normally driving in the cold long enough to meaningfully impact range. ... some charge power throttling does still occur to avoid excessive battery pack heating. 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. Is Nissan really going to go without active liquid cooling yet again, even after all of the problems it has caused LEAF customers in the past?

My understanding is that it takes outside air and pumps the "heat from that air" which explains why it isn't helpful in the extreme cold but I don't know when I would need heat when it's warmer outside than in my car. 2019 Kia Niro EV first drive - Santa Cruz, CA - February 2019. (adsbygoogle = window.adsbygoogle || []).push({}); Appreciate CleanTechnica’s originality?

And if you do need to hypermile your car on long drives in the winter, you sure picked the wrong car, heater or no!

A few follow up questions for you if you don't mind. Press question mark to learn the rest of the keyboard shortcuts. It’s my sad prediction that a charge throttling “solution” looks set to still be an unwelcome but reliable “feature” of the 60 kWh LEAF, especially on long high-speed highway drives requiring several DC charges in warm and hot climates. Electrive recently spoke with Nissan dealer circles in Germany and uncovered some new (and as yet unconfirmed) information about the eagerly anticipated 60 kWh LEAF. Heat pumps don’t solve the cold-weather range punch, but they do soften the blow.

Also, I see condensation brought up a lot. I agree to receive emails from Green Car Reports. Heat pumps aid efficiency because they move heat rather than generate it. Thanks to Arnis Tarassu for pointing that out. ] Heating especially gets skipped over in the EPA’s driving-cycle calculations for EVs. Stock photography by. Even with this, some charge power throttling does still occur to avoid excessive battery pack heating. © 2020 MH Sub I, LLC. Partly to blame is that the resistive heating electric cars rely on (yes, like those glowing elements in your toaster) takes a lot of energy. And with a smart thermal management system that Bosch introduced in 2015, it claimed 25 percent better range in wintry urban situations. Despite these hopes, according to the news, the 60 kWh LEAF will stick with air cooling, albeit this time with some active fans (not present in the current LEAF) and, I would speculate, a cold-air-redirect from the passenger compartment’s air conditioning cooler. Thanks! Thanks! The current LEAF and e-NV200 both have the 40 kWh pack, typically charging at between 35 and 45 kW.

New comments cannot be posted and votes cannot be cast, Press J to jump to the feed. If the heater is using 3kW, this 10 minutes is 0.5kWh, or maybe 1.5 miles of lost range. Climate control systems that take full advantage of heat-pump systems increase the vehicle’s cost by a few hundred dollars, we’ve been told, while resistive heat is cheap.

Here’s a reminder of the massive amounts of heat added during a single DC fast charge of the current 40 kWh LEAF (consider that this is only at 46 kW peak charging power): Given that a 70% top-up on the current LEAF, even limited to 46 kW, adds 20° Celsius worth of heat to the pack, it seems unavoidable that a 50% greater amount of energy added via 92 kW charging will — other things being equal — add at least twice the heat (yes, that’s 40° Celsius of added heat from a single DC charge). I had one with and one without.

Der Nissan Leaf (englisch für „Blatt“; LEAF auch als Backronym Leading Environmentally-friendly Affordable Family car interpretiert) ist ein Elektroauto des japanischen Automobilherstellers Nissan, das im August 2009 in Yokohama der Öffentlichkeit vorgestellt wurde und seit Dezember 2010 verkauft wird.

This is the type of battery cooling system employed in the current 40 kWh Nissan e-NV200 light commercial van. 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.
