China-made electric vehicles (EVs) accounted for 14.2 percent of European market sales in the first five months of 2026 despite the EU's steep tariffs. The growth showed that trade‑protectionist barriers can only serve as short‑lived obstacles, as consumers' purchasing choice ultimately hinges on product competitiveness and China's EV strengths will support the automakers' long‑term growth, Chinese experts said.
The market share of electric cars sold by Chinese companies rose to 14.2 percent in European market in the first five months of this year, according to Schmidt Automotive Research. The 171,800 EVs sold there represented an increase in market share of five percentage points from one year earlier, the Guardian reported on Sunday.
The increase in European sales comes despite EU tariffs of up to 35.3 percent for EVs made by some Chinese manufacturers, on top of the standard 10-percent import duty. The UK is the largest European market for Chinese cars because London has declined to follow the EU's lead in imposing more levies. The UK accounted for a quarter of Chinese EV sales in Europe, according to the report.
Cui Dongshu, secretary-general of the China Passenger Car Association, told the Global Times on Monday that the surge showed trade protectionist policies have failed to contain Chinese automakers' overseas expansion.
Chinese EVs enjoy "a generational edge" over Europe's legacy carmakers. Their overall product strength remains the primary reason behind their popularity among European buyers, Cui said.
Meanwhile, fluctuating global oil prices have pushed up driving costs throughout Europe, fueling demand for affordable electric vehicles, a need well‑met by the affordable Chinese‑made models. Meanwhile, the gradual return of European electric‑vehicle purchase subsidies has lowered purchase barriers and lifted total EV sales, which has in turn worked to the advantage of Chinese exporters, Cui Dongshu said.
Chinese brands expanded their market share in Europe in the first half of 2026 driven by local subsidies and higher oil prices, Fitch Ratings said in a report sent to the Global Times.
The combined market share of leading Chinese brands in the EU, European Free Trade Association and UK rose to 11 percent in the first half of this year, up from 7 percent in the first half of 2025. The largest Chinese players, Geely Group (including Volvo Car) and SAIC Motor, expanded steadily despite the tariffs. The main drivers of market share gains were BYD, Chery and Leap Motor, according to Fitch Ratings.
Cui Dongshu noted that China's EV edge comes from its full‑fledged industrial ecosystem.
Officials from China's Ministry of Commerce told a press conference on July 28 that China boasts a complete, high‑efficiency EV industrial chain covering raw materials, auto parts, finished cars and production equipment, with industry clusters enabling rapid component supplies. China's huge market, the world's largest, has fueled 11 consecutive years of EV sales.
"Protectionism can only put up short‑term entry barriers. It cannot erase the solid strengths of Chinese EVs or stop Chinese brands from establishing a lasting foothold in Europe," Cui Dongshu said.
Yet, geopolitical risks remain as the EU reportedly considers expanding tariffs to restrict Chinese plug-in hybrid EVs.
German media Handelsblatt reported on June 19 that the EU is drawing up new measures to shield its single market more tightly against Chinese imports in the near future, citing senior EU officials and industry insiders. Specifically, the plan could contain countervailing duties to be levied on Chinese‑made plug‑in hybrids.
The rising market share of Chinese‑brand EVs amid EU tariffs has demonstrated that trade barriers cannot distort market choices. If the EU carries out its planned countervailing duties on Chinese plug‑in hybrids, the measure will yield only limited results, Cui Hongjian, a professor at the Academy of Regional and Global Governance at Beijing Foreign Studies University, told the Global Times on Monday.
Europe's problems stem from weak competitiveness and flawed energy policies. The EU ought to cast aside its confrontational mindset, remove unfair restrictions and pursue consultations and cooperation with China. Shifting industrial‑sector conflicts outward cannot remedy the weaknesses of its EV sector and will only damage the EU's reputation for destroying free trade, Cui Hongjian said.

B | 《8视界新闻网》早前报道，位于先驱区建德路（Kian Teck Road）的一间单层工厂，放置在锌（zinc）屋顶上的太阳能电池板着火。根据民防部队初步调查，火患相信是由太阳能电池板的电能所引起。（图：iStock）太阳能板可能起火的原因有哪些？ 接受《8视界新闻网》访问的太阳能电池板公司表示，有多种原因会导致太阳能板可能起火，包括安装不当、劣质零件、电气故障（如短路或电弧故障）、连接松动、制造缺陷、操作错误或检查不频繁等。太阳能电池板公司 Sunollo 首席执行官卡皮尔·赛斯（Kapil Seth）受访时说，太阳能光伏系统（Solar PV system），特别是那些高电压串联的系统，容易因电弧（electric arc）而引发火灾。“电弧是在电流仍在流动时连接被中断时产生的，会导致火花，因而可能引发火灾。

C | 这些电弧的电压可以高达1000伏，非常危险。”他说，有研究显示，电气电孤是屋顶太阳能蓄电池起火最常见原因，通常是因为连接器出现故障所致。太阳能电池板公司GetSolar创办人之一周博隆则说，其他原因还包括在安装或维修太阳能电池板的过程中，因为不当处理，如踩踏电池板也会导致电池板受损。他也说：“低质量的电池板，会存在制造缺陷。”电缆的连接问题，也可能导致火患。太阳能电池板公司PMCE (Global)董事萨蒂什 （Satish）说，太阳能板起火的主要原因是屋顶上的电缆连接不当。“在安装过程中，细节至关重要，必须确保所有布线正确连接且牢固可靠，因为连接不稳可能导致过热和火花，进而引发火灾。

E | ”卡皮尔·赛斯则给予不同的建议，他建议消费者安装太阳能瓦片（solar titles）或安装使建材一体型太阳光电系统（Building-Integrated Photovoltaics）。他说，太阳能瓦片既能像传统屋顶材料一样美观实用，同时还能发电。“这些瓦片由光伏材料制成，能够将阳光转化为电能，最重要的是太阳能瓦片不会引发火患。”值得一提，安装太阳能瓦片的费用与安装普通太阳能板的费用一样，所以是个再好不过的选择。使建材一体型太阳光电系统（Building-Integrated Photovoltaics）。

F | （图：Sunollo提供）安装太阳能板 大大节省电费 受访的太阳能电池板公司都认为，本地企业安装太阳能电池板的情况已经越来越普及。周博隆说，新加坡企业安装太阳能板的市场正在迅速增长，他的公司在过去两年已为近300多名业主安装太阳能。他说，安装太阳能板能节省多少费用，视乎公司的屋顶大小和能耗而异。

G | “一般上太阳能板可以抵消30%至50%的能耗，例如，我们为其中一个客户约1500平方米的屋顶空间，每月节省约8000元。

H | ”萨蒂什也认为，新加坡企业对太阳能的需求相当高。

I | “我们公司每天平均进行五次安装。

J | 客户通过转向太阳能，可以将电费降低多达80%。”郑君实则说，公司可以显著节省电费，通常能将电费降低20%至50%。
