In Spain the development of public fast chargers is mainly driven by the utility companies which also build charging stations for private owners.<ref>{{cite web|url=https://www.rolandberger.com/en/Insights/Publications/EV-Charging-Index-Expert-insight-from-Spain.html|title=EV Charging Index: Expert insight from Spain|publisher=Roland Berger|date=2023-08-21|author=Juan Luis Vilchez}}</ref> Along the motorways it is mostly [[Iberdrola]] being active, which received 1 billion Euro through an agreement with BP in 2023 in order to build 11,000 fast chargers, mostly HPC stations.<ref>{{Cite web |last=Latief |first=Yusuf |date=2023-03-05 |title=Iberdrola and bp to fast charge Spain and Portugal with €1bn EV investment |url=https://www.smart-energy.com/industry-sectors/electric-vehicles/iberdrola-and-bp-sign-e1bn-alliance-for-evs-in-spain-and-portugal/ |access-date=2023-11-02 |website=Smart Energy International |language=en-ZA}}</ref><ref>{{Cite web |last=Hill |first=Joshua S. |date=2023-03-06 |title=Iberdrola and BP to deploy 11,700 fast and ultra-fast charging points in Spain and Portugal |url=https://thedriven.io/2023/03/07/iberdrola-and-bp-to-deploy-11700-fast-and-ultra-fast-charging-points-in-spain-and-portugal/ |access-date=2023-11-02 |website=The Driven |language=en-US}}</ref><ref>{{Cite web |last=Mavrokefalidis |first=Dimitris |date=2023-03-03 |title=Iberdrola and bp to invest €1bn in fast charging infrastructure |url=https://www.energylivenews.com/2023/03/03/iberdrola-and-bp-to-invest-e1bn-in-fast-charging-infrastructure/ |access-date=2023-11-02 |website=Energy Live News |language=en-US}}</ref> Additionally there is the startup [[Zunder]] that started to build HPC chargers.

=== trend 800 V ===
With the Taycan from 2019, Porsche was the first manufacturer to be able to use the doubled charging speed of the HPC chargers with an on-board architecture of 800 volts - actually it maxed out at 270 kW. However, it turned out that you can also use the doubled charging speed with the already common on-board architecture in 400 volts - if you have the battery pack in two parts and connect them in series. This was first shown by GM with the electric [[GMC Hummer EV]] in 2021. Due to its particularly large battery block of 213 kWh, this has been necessary in order to stay under one hour for a full charge on the go. The first electric trucks also used 400 volt battery packs that can be connected in series, as the [[Mercedes Benz#eAtros|Mercedes Benz eActross 400]] (2022) was able to show. Here too, the size of the battery block of up to 336 kWh is driving development forward.
However, installing a [[battery management system]] for several battery packs increases complexity and costs, so that with the increasing availability of HPC networks, all vehicle manufacturers began to develop an on-board architecture in 800 volts. This can be based on electronics from the field of trams and subways, which are nominally designed for 750 volts of traction current, including motors that can tolerate load peaks of up to around 1200 volts. Based on that, there are some start-ups that use the maximum of 1000 volts of the HPC chargers for their vehicles, at the expense of slightly lowering the durability.
In addition to Porsche's innovation, whose 800-V architecture was also used in the [[Audi e-tron GT]] (2021), it was Hyundai to develop the [[E-GMP]] platform with 800 V early on, which was used in vehicle models from 2021 - [[Genesis GV60]] (2021), [[Kia EV6]] (2021), [[Hyundai Ioniq 5]] (2021), [[Hyundai Ioniq 6]] (2022), [[Kia EV5]] (2023). BYD developed the "E-Platform 3.0" - while the [[BYD Yuan Plus]] (2022) still used its 400 V variant in China, the [[BYD Seal]] (2023) came with the 800 V variant being sold sold internationally. Geely developed the [[Sustainable Experience Architecture]] (SEA), which was expanded to include an 800 Volt variant, also licensing it to other vehicle manufacturers. Vehicles with the PMA2+ variant were the [[Geely Galaxy E8]] (2023) and [[Zeekr 007]] (2023).
From 2024 onwards, all major manufacturers started switching to 800 volts. Audi and Porsche will use the Volkswagen Group's [[Premium Platform Electric]], that includes [[Porsche Macan]] (2024) and [[Audi Q6 e-tron]] (2024). BMW showed the "New Class" at the IAA 2023 with new models from 2025. Mercedes Benz is switching to the Mercedes Modular Architecture (MMA), whose electric motors in the "eATS 2.0" series are based on 800 volts.
The spread of 800 V influences the development of fast charging networks. In order to remain future-proof, most HPC charging stations had been designed from the start to support charging voltages of up to 1000 V. However, there are many charging stations types with two or more connection cables that can only be operated at up to 500 volts at the same time - if a vehicle is connected with 800 volts, the other charging points are switched off. With the increasing use of 800-volt architectures, the future charging networks must be designed accordingly, and at the same time they must plan for the increase in load above 500 A.
