What am I talking about? Heat pumps of course!<\/p>\n<p>The idea is that heat pumps prevent excess heat created by an EV\u2019s battery and drivetrain from going to waste.\u00a0<span>They absorb the excess heat generated by\u00a0<\/span><span class=\"c-mrkdwn__highlight\">EV<\/span><span>\u2018s battery and drivetrain to improve the\u00a0<\/span><span class=\"c-mrkdwn__highlight\">car<\/span><span>\u2018s efficiency, range, and driving experience.<\/span><\/p>\n<p>The name sounds simple enough, but what exactly do they do? And why are they important for electric vehicles? Let\u2019s dive in and answer some of those questions.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_it\"><\/span><strong>What is it?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Put simply, a heat pump is a device used to move heat around an electric vehicle. Similar concepts are used in combustion engine cars, but we don\u2019t care about those right now.<\/p>\n<p>Reversible heat pumps can also generate heat, and then move that around an EV as it\u2019s needed, but we\u2019ll get on to that later.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Lets_go_deeper\"><\/span>Let\u2019s go deeper<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>But why do we need to move heat around? Well, to be honest, we don\u2019t. We could simply cool the battery and motors, and dump that heat back into the atmosphere using radiators. But that\u2019s kind of wasteful, and that\u2019s not at all in the spirit of electric vehicles.<\/p>\n<p>One core function that heat pumps perform, is to take heat away from the hot parts of the car that would otherwise be wasted, and direct it to the passenger cabin. This means that the EV doesn\u2019t need to use its battery to power a resistive heater, to keep passengers comfortable.<\/p>\n<figure class=\"post-image post-mediaBleed aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-1337353 lazy\" alt=\"Tesla, model y, heat pump\" width=\"816\" height=\"436\" sizes=\"auto, (max-width: 816px) 100vw, 816px\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/02\/Screenshot-2021-02-03-at-12.01.11.png\" data-lazy=\"true\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/02\/Screenshot-2021-02-03-at-12.01.11.png 1640w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/02\/Screenshot-2021-02-03-at-12.01.11-280x150.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/02\/Screenshot-2021-02-03-at-12.01.11-505x270.png 505w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/02\/Screenshot-2021-02-03-at-12.01.11-252x135.png 252w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/02\/Screenshot-2021-02-03-at-12.01.11-796x426.png 796w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/02\/Screenshot-2021-02-03-at-12.01.11-1592x851.png 1592w\"\/><figcaption>Credit: <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.youtube.com\/watch?list=TLGGQhy4xOdY6wUwMzAyMjAyMQ&amp;v=dxKdVk3A4nI&amp;feature=emb_title\"> D\u00c6rik &#8211; YouTube<\/a><\/figcaption><figcaption><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/thenextweb.com\/shift\/2021\/02\/03\/whats-a-heat-pump-and-why-do-evs-use-them\/#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Fthenextweb.com%2Fshift%2F2021%2F02%2F03%2Fwhats-a-heat-pump-and-why-do-evs-use-them%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: The Tesla Model Y heat pump as demonstrated by Andy Slye of D\u00c6rik YouTube channel.\" data-title=\"Share The Tesla Model Y heat pump as demonstrated by Andy Slye of D\u00c6rik YouTube channel. on Twitter\" data-width=\"685\" data-height=\"500\" class=\"post-image-share popitup\" title=\"Share The Tesla Model Y heat pump as demonstrated by Andy Slye of D\u00c6rik YouTube channel. on Twitter\"><i class=\"icon icon--inline icon--twitter--dark\"\/><\/a>The Tesla Model Y heat pump as demonstrated by Andy Slye of D\u00c6rik <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">YouTube<\/a> channel.<\/figcaption><\/figure>\n<p>Less use of the main battery means improved range and improved efficiency. See how this is working? It\u2019s really simple. This is all fine when temperatures outside the vehicle are just cool, but what about when it\u2019s much <em>much <\/em>colder?<\/p>\n<p><em>[Read: How much does it cost to buy, own, and run an EV?

As <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.wired.com\/story\/electric-cars-cold-weather-tips\/\">cold<\/a> climate EV drivers know, an ice-cold battery is very inefficient and can have a detrimental impact on range. Here\u2019s where reversible heat pumps come in.<\/p>\n<p>As mentioned, reversible heat pumps can also generate heat. They do this by compressing the refrigerant that flows through the cooling system \u2014 under compression, refrigerants get hot.<\/p>\n<p>That heat can then be moved around the car\u2019s cooling and heating system to put heat where it\u2019s needed, for example in the battery.<\/p>\n<p>It\u2019s actually more efficient to use warm the battery before setting off on your journey, instead of waiting for it to warm itself through use. What\u2019s more, as most EVs can \u201cprecondition\u201d before unplugging from their charger, you can leave with a warm battery, full of power, that won\u2019t be adversely impacted by the cold weather.<\/p>\n<p>If you\u2019re keen to go into even more detail on how heat exchangers and pumps work, watch this video from Jason Fenske at Engineering Explained over on YouTube.<br \/>\n<iframe loading=\"lazy\" title=\"Tesla Model Y - The Only Tesla With A Heat Pump\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/S7wxGl7m2sw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Whats_the_fuss\"><\/span>What\u2019s the fuss?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Hopefully that all makes sense. <span>Heaters can create perfect operating temperatures for the battery in freezing situations. And in non-freezing, but cold, situations they can heat up the cabin and save battery power.<\/span><\/p>\n<p>Some claim that Tesla\u2019s heat pump system in its Model Y is <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.tesmanian.com\/blogs\/tesmanian-blog\/tesla-model-y-heat-pump-range\">300% more efficient<\/a> than its resistive heating unit that it has used previously. This can have a dramatic impact on range when driving in cold weather.<\/p>\n<p>Well-known EV reviewer and tester Bjorn Nyland, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.teslarati.com\/tesla-model-3-heat-pump-test-video\/\">tested two near identical Tesla Model 3\u2019s<\/a>, one with a heat pump and one without, and seemed to confirm this boost in efficiency.<\/p>\n<p>Nyland used camp mode, a setting which maintains a cabin temperature, to see how much more efficient the heat pump is compared to the older heating ventilation and air conditioning (HVAC) system. After three hours of maintaining a cabin temperature in frosty Norway, the heat pump-equipped Tesla had lost 3% of battery charge, whilst the older Model 3 lost 10%. <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.youtube.com\/watch?v=GRubEJh_5gs&amp;feature=emb_title\">Watch his full test here<\/a>.<\/p>\n<p>It\u2019s not just Tesla that\u2019s using heat pumps, though. Nissan claims to be the first to have used the tech on a mass market EV, and they can also be found in BMW i3s too. If anything, Tesla was kind of late to the party, but is now installing its tech on its new vehicles.<\/p>\n<p>It goes without saying, anything that improves the range and efficiency of an EV is a good thing. Heat pumps get a thumbs up from us.<\/p>\n<hr\/>\n<p><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.polestar.com\/nl\/polestar-and-shift?utm_medium=pp&amp;utm_source=dp&amp;utm_campaign=pcid_3450_41261_85609_351306_p_nl_1local_pp_dp&amp;utm_content=ad\"><\/p>\n<figure class=\"post-image post-mediaBleed alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1308892 lazy\" alt=\"\" width=\"221\" height=\"100\" sizes=\"auto, (max-width: 221px) 100vw, 221px\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/07\/Polestar_wordmark_pos.png\" data-lazy=\"true\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/07\/Polestar_wordmark_pos.png 3003w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/07\/Polestar_wordmark_pos-280x127.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/07\/Polestar_wordmark_pos-540x245.png 540w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/07\/Polestar_wordmark_pos-270x123.png 270w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/07\/Polestar_wordmark_pos-796x361.png 796w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/07\/Polestar_wordmark_pos-1592x723.png 1592w\"\/><\/figure>\n<p><\/a><i>SHIFT is brought to you by Polestar.
