The new Mercedes-Benz CLA is generating buzz as it steps into the electric vehicle (EV) arena, boasting an impressive 492-mile range. However, there’s a catch that potential buyers should be aware of: this sleek EV won’t be able to utilize 400V DC chargers, which are quite common across the UK and Europe. So, what does this mean for drivers looking to make the switch to electric?<\/p>\n

Understanding the Charging Limitations<\/p>\n

The third-generation CLA is built on Mercedes’ new MMA electric car platform, but it lacks a crucial component\u2014a DC-to-DC voltage booster. This absence means that the CLA can only fast-charge at stations that supply 800 volts. While this might sound high-tech and efficient, it also limits compatibility with many existing charging stations, particularly older 50kW units and the majority of Tesla Superchargers currently in operation.<\/p>\n

In the UK alone, there are over 14,000 public charge points capable of 50kW charging or faster, according to Zap-Map. However, the majority of these are 400V chargers, which can deliver up to 250kW. The newer 800V charging stations, while capable of charging at speeds nearly double that, are still not as widespread. This discrepancy raises questions about the practicality of owning a CLA EV, especially for those who rely on public charging infrastructure.<\/p>\n

Cost-Saving Decisions and Consumer Impact<\/p>\n

Mercedes has indicated that the decision to omit the 400V DC converter is likely a cost-saving measure. The thinking seems to be that most customers will primarily charge their vehicles at home using an AC connection. In this scenario, 400V AC is converted into 800V DC internally for battery use, which may make the omission less impactful for home chargers. However, for those who frequently use public charging stations, this limitation could pose significant inconveniences.<\/p>\n

A spokesperson for Mercedes mentioned that the share of 800V DC fast-charging stations is on the rise, and drivers will be directed to compatible stations via the navigation system. This real-time update feature is a nice touch, but it doesn\u2019t fully address the concern of limited charging options for CLA owners, especially in regions where 400V chargers are still prevalent.<\/p>\n

Comparing Approaches: How Rivals Handle Charging<\/p>\n

Interestingly, other manufacturers have taken a different route. Brands like Hyundai and Kia have equipped their E-GMP-platform EVs, such as the Ioniq 5 and EV6, with internal voltage boosters. This allows for seamless charging from both 400V and 800V stations, providing greater flexibility for drivers. On the other hand, Porsche and Audi have implemented a split-pack battery strategy in their PPE-platform EVs, allowing for charging at 400V, albeit at reduced speeds.<\/p>\n

Mercedes\u2019 choice not to include similar solutions in the CLA raises questions about their strategy in a competitive market. While the company is focusing on the future of charging infrastructure, the current landscape still includes many 400V chargers, especially in countries like Norway, where EV charging networks were established earlier.<\/p>\n

What\u2019s Next for the CLA EV?<\/p>\n

There are reports suggesting that the CLA EV sold in Norway might come equipped with the DC-to-DC booster, but it’s unclear if this feature will extend to models in other European markets. Interestingly, the online configurators for Mercedes in Belgium and the Netherlands make no mention of the charging limitation, which could lead to confusion for potential buyers.<\/p>\n

As the automotive landscape continues to evolve, the CLA’s charging capabilities will be a critical factor for consumers weighing their options. While the promise of a long range is enticing, the practicality of charging infrastructure cannot be overlooked.<\/p>\n

The big takeaway? The Mercedes-Benz CLA EV isn\u2019t just about sleek design and impressive range; it\u2019s also about navigating the complexities of charging options. If you\u2019re considering making the switch to electric, it\u2019s worth evaluating your charging habits and the availability of compatible stations in your area. Start with one change this week, and you\u2019ll likely spot the difference by month\u2019s end.<\/p>\n","protected":false},"excerpt":{"rendered":"

\"Merc<\/a><\/p>\n

The omission of a 400V DC converter is thought to be a cost-saving measure by the German brand<\/p>\n

\n

The incoming electric Mercedes-Benz CLA<\/a>, the German brand’s game-changing EV that promises a 492-mile range, is unable to use any 400V DC charger – a common standard across the UK and Europe.<\/p>\n

This means the third-generation CLA, based on the German firm’s new MMA electric car<\/a> platform,\u00a0<\/span>is incompatible with\u00a0many older 50kW units and most Tesla<\/a> Superchargers currently in operation.<\/p>\n

This is because it\u00a0lacks a DC-to-DC voltage booster, meaning\u00a0it can only fast-charge at stations that supply 800 volts – typically found on newer HPC (high-power charging) networks that can charge at speeds almost double that of 400V.<\/span><\/p>\n

The UK currently has 14,448 public charge points\u00a0capable of\u00a050kW charging or faster, according to Zap-Map. Although the data doesn’t include the voltage of the chargers, Zap-Map does confirm\u00a0that while 800V charging (up to 350kW) is available at some locations, it’s not nearly as widespread as 400V charging (up to 250kW), given that it’s a\u00a0newer\u00a0– and therefore much more expensive\u00a0– technology.<\/p>\n

The omission of a 400V DC converter is thought to be a cost-saving measure, the likely thinking being that the majority of\u00a0customers will charge their CLA mostly at home via an AC connection\u00a0\u2013<\/span>t<\/span>here,\u00a0400V AC flows into an onboard charger and is converted into 800V DC internally for battery use.<\/span><\/p>\n

Mercedes<\/a> confirms the charging limitation on its German website configurator with the message “charging at 400V charging stations is not possible”.<\/p>\n

Backing its decision, a spokesperson for the car maker told Autocar that “the share of 800V DC-fast-charging stations in the entire charging network is constantly increasing” adding that drivers will only be “directed to a compatible charging station” via the navigation system. “<\/span>The update of available and compatible charging stations works almost in real time,” it said.<\/p>\n

Asked if there would be a paid\u00a0option to fit a DC converter for the UK market, the spokesperson said: “We cannot comment on this now.”<\/p>\n

Rival car makers have taken a different approach. Hyundai<\/a> and Kia<\/a> equip their E-GMP-platform EVs, including the Ioniq 5<\/a> and EV6<\/a>, with internal voltage boosters to allow 400V-800V\u00a0conversion, enabling charging even from older DC stations.<\/p>\n

Meanwhile,\u00a0Porsche<\/a> and Audi<\/a> use a split-pack battery strategy with their PPE-platform EVs, such as the\u00a0Macan Electric<\/a>\u00a0and\u00a0A6 E-tron<\/a>, dividing the battery into two 400V sections for charging (albeit at reduced speeds).<\/p>\n

Mercedes has chosen not to implement either solution in the CLA EV sold in selected European markets. There is still a DC-DC converter onboard, but\u00a0it’s only used to supply 12V\u00a0power to auxiliary systems such as seat heating and infotainment.\u00a0<\/p>\n

While 400V chargers are being replaced by 800V chargers across Europe, many 400V chargers still remain, particularly in countries such as Norway, where the EV charging infrastructure was established much earlier than in other countries.<\/p>\n

Reports suggest the new CLA EV to be sold in Norway will be fitted with the DC-to-DC booster, but it remains unclear if this will be included on models offered in other European countries.<\/p>\n

Mercedes’ Belgian and Dutch online configurators make no mention of the charging limitation.<\/p>\n

Autocar has asked Mercedes for clarification on the specification of the CLA EV to be sold in the UK\u00a0but has yet to receive a reply.\u00a0<\/p>\n<\/div>\n","protected":false},"author":1,"featured_media":62952,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"Default","format":"standard","meta":{"footnotes":""},"categories":[2,137],"tags":[],"class_list":["post-62951","post","type-post","status-publish","format-standard","has-post-thumbnail","category-featured","category-news"],"_links":{"self":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts\/62951","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/comments?post=62951"}],"version-history":[{"count":0,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts\/62951\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/media\/62952"}],"wp:attachment":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/media?parent=62951"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/categories?post=62951"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/tags?post=62951"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
