EV charging points Types, power levels and requirements for cars and trucks.
Practical guide to choosing and sizing EV chargers for homes, businesses and fleets: AC wallboxes, DC fast charging, Type 2, CCS2, MCS, protections, available power and regulations.
Which charging point does each electric vehicle need?
A car that spends all night in a garage, a van that returns to base every afternoon and a truck that must recover hundreds of kilowatt-hours (kWh) during a logistics stop do not need the same charging point. Rated power is only one part of the project.
To size the installation, you need to know daily energy demand, actual connection hours, simultaneity, available power, connector type, expected growth and whether the service will be private, shared or publicly accessible.
With these data, you can decide whether an AC wallbox with dynamic load management, a DC fast-charging station, modular fleet infrastructure or a dedicated truck hub with CCS2 or MCS is the right option.
What is an EV charging point and how does it work?
The visible charging point is only one part of the system. The complete installation includes power supply, conduits, switchboards, protections, metering, control, communications, civil works and, at public stations, identification, payment and user information.
From the electrical grid to the battery
The installation must transfer energy safely, limit demand, protect people and equipment, identify consumption and maintain service availability.
Types of EV chargers: AC, DC, Type 2, CCS2 and MCS
When comparing charging points, it is not enough to say “slow”, “fast” or “ultra-fast”. You need to distinguish the charging mode, alternating current (AC) or direct current (DC), connector, station power and the maximum power accepted by the vehicle.
Mode 2 · cable with integrated control
The vehicle connects to a standardized socket through a cable that incorporates control and protection functions. ITC-BT-52 limits this mode to 32 A.
Mode 3 · wallbox or AC station
Direct connection to the grid through fixed EVSE. It is the usual solution for homes, residential communities, car parks, businesses and fleets with sufficient parking time.
Mode 4 · DC station
The AC/DC converter is external to the vehicle. The station delivers direct current straight to the battery and enables much higher power levels, from tens of kW up to the megawatt range.
Which charger does an electric car, van or truck need?
Select the vehicle type to compare batteries, power levels and charging strategies. The ranges are indicative: final sizing depends on the model, route, kWh to replenish and available electrical capacity.
Make the most of parking time with a managed wallbox
For most daily journeys, there is no need to fully recharge the battery every night. An AC charging point with dynamic load management can replenish the required kWh without exceeding the power available at the home or business.
MCS for electric trucks: megawatt-range charging
Long-haul trucks combine large batteries with limited charging windows. MCS increases voltage and current, incorporates thermal management and provides a dedicated interface for trucks, buses and other high-power applications.
It is not just more power: it is a different charging architecture
The IEC specification published in January 2026 standardizes the vehicle connector, inlet and cable assembly for megawatt-range DC charging. The 4.5 MW limit is theoretical; actual power will depend on the equipment, vehicle, grid and thermal management.
In many truck projects, CCS2 will continue to cover overnight or opportunity charging. MCS makes sense when the operating window requires transferring a large amount of energy in a short time.
Benefits of charging points for individuals, businesses and fleets
The value does not come from installing more kW than necessary, but from ensuring vehicles are available, energy costs remain controllable and the installation can grow without having to be rebuilt.
Operational availability
Vehicles recover the energy they need within their actual parking window without oversizing the entire installation.
Demand control
Load balancing limits peaks, distributes power and can reduce the need to upgrade the supply from day one.
Centralized management
Users, consumption, authorizations, alarms, tariffs, reports and maintenance can be managed from one platform.
Energy integration
Charging can be coordinated with solar PV, stationary batteries, time-of-use tariffs and other loads.
Safety and traceability
Dedicated circuits, correct protections, metering, access control and maintenance reduce risks.
Fleet scalability
Conduits, switchboard space, modular architecture and reserved capacity allow phased growth.
An electric vehicle produces no tailpipe emissions during use and reduces propulsion noise, but its total impact depends on manufacturing, the source of electricity, efficiency and operation. “No local emissions” does not mean “zero impact”.
How to install a charging point: technical and legal requirements
The installation must start from the vehicle’s real needs and end with a system that is calculated, protected, documented, legalized and ready to grow. For fleets, public charging and heavy-duty transport, the electrical grid, management software and maintenance are as important as the charger.
Define operations and daily energy
Vehicles, batteries, kilometres, consumption, arrival state of charge (SOC), required SOC, parking hours, shifts, routes, peak days and expected growth.
Check the vehicle, connector and charging curve
Maximum AC and DC power, battery voltage, Type 2, CCS2 or MCS, inlet position, cable length, authentication and power sharing.
Analyse the installation and connection point
Contracted power, maximum demand, conductor cross-sections, switchboards, transformer, voltage drop, short-circuit level, power quality, harmonics and space for expansion.
Choose the electrical scheme and power management
ITC-BT-52 allows several schemes. You need to decide whether charging shares the supply, has its own meter or uses collective circuits, and whether it incorporates an SPL or dynamic load balancing.
Project, technical report and permits
You must determine whether a technical project, technical report, initial inspection, building permit, occupancy permits or utility approvals are required. Mode 4 stations require a project.
Electrical and mechanical protections
Dedicated circuit, individual RCD up to 30 mA, overcurrent protection, temporary and transient overvoltage protection, protective conductor, earthing, IP/IK ratings, bollards, drainage and lighting.
Accessibility, circulation and operation
Bay width and length, turning radii, truck entry and exit, connector position, operating height, colour contrast, signage and separation from other hazards.
Commissioning, software and maintenance
Certification, responsible declaration, testing, limits, users, tariffs, payment, OCPP or equivalent platform, data communication, alarms, support and preventive maintenance.
Where to install charging points: homes, businesses, fleets and hubs
Power and charger type vary depending on available time, number of vehicles and site use. These four scenarios summarize the most common configurations.
Car with overnight charging
The available charging window is long and daily demand is usually moderate. Dynamic control prevents the home or building’s available power from being exceeded.
Shared charging points in businesses and car parks
Limited aggregate power is distributed according to schedule, priority, energy still required, user or departure time.
Charging vans and trucks at a fleet depot
Planning combines route energy requirements, departure times, shared chargers, manoeuvrability and grid availability.
Fast-charging hub for cars and heavy-duty transport
Requires high availability, payment systems, transparent pricing, communications, redundancy, civil works and high grid capacity.
EV charging point regulations in Spain and Catalonia
ITC-BT-52, ITC-BT-04, CTE DB-HE 6, Royal Decree 184/2022 and the AFIR Regulation form the core regulatory framework. Power, location, building type and public access can trigger additional obligations.
ITC-BT-52: supply, schemes and protections
It regulates connection schemes, load forecasts, connection points, circuits, protections and installation conditions.
ITC-BT-04: when a project is mandatory
The amendment introduced by Royal Decree 1053/2014 sets specific thresholds for charging infrastructure.
CTE DB-HE 6: minimum provisions in buildings
It applies to new buildings and certain works in existing buildings with parking facilities.
Existing car parks with more than 20 spaces
It established minimum provisions with a deadline before 1 January 2023 for existing non-residential buildings and car parks.
Public charging points: pricing, payment and interoperability
A public charging point is also a consumer service, with obligations regarding accessibility, pricing, payment, information and interoperability.
Catalonia: notification, registration and commissioning
Public operators must provide static information and, in certain cases, dynamic information. In Catalonia, low-voltage installations are documented in RITSIC.
The AFIR Regulation sets public deployment targets for heavy-duty vehicles on the TEN-T network, urban nodes and safe parking areas. These targets do not replace the private sizing of a depot, but they indicate the level of power and interoperability toward which European infrastructure is evolving.
Checklist for sizing an EV charging installation
Tick the data you already have defined. The score does not validate the installation, but it helps identify what information is missing before selecting chargers or requesting a technical quotation.
How many decisions have really been finalized?
A quotation based only on “I want four 22 kW chargers” may overlook daily energy demand, grid capacity, manoeuvrability, legal compliance, payment or future growth.
Frequently asked questions about EV charging points
How much power does an electric car need?
It depends on the kWh that need to be replenished and the time available. For destination charging, 7.4, 11 or 22 kW are common, but the vehicle may limit AC power. A full recharge is not always necessary every day.
Does a 22 kW charger always charge at 22 kW?
No. The vehicle may only accept 7.4 or 11 kW AC, dynamic load management may limit the session, and the available power may be shared between several points.
What is the difference between Type 2 and CCS2?
Type 2 is the common European interface for AC charging. CCS2 adds DC contacts and enables high-power DC charging while keeping the upper section compatible with Type 2.
Can an electric truck use CCS2?
Yes, many current electric trucks use CCS2. The bay, cable, connector position, power and manoeuvrability must be designed for heavy-duty vehicles.
When is MCS appropriate?
When a large battery must recover a lot of energy in a short window and CCS2 cannot meet operational requirements. Route, stops, battery, available infrastructure and the fleet renewal schedule must be analysed.
Can an increase in contracted power be avoided?
Often, an upgrade can be postponed or reduced through dynamic load balancing, scheduling, prioritization and limiting aggregate power. In DC hubs or truck depots, however, it may be necessary to reinforce the service connection or install a dedicated transformer.
Is a technical project mandatory?
Among other cases, yes: when EV infrastructure exceeds 50 kW, when an outdoor installation exceeds 10 kW or when it includes Mode 4 stations. Stricter criteria may also apply depending on the use of the premises.
What protections does ITC-BT-52 require?
Dedicated circuit, protective conductor, earthing, individual RCD up to 30 mA, overcurrent protection, temporary and transient overvoltage protection, and suitable environmental and mechanical protection ratings.
What changes if the charging point is publicly accessible?
In addition to the electrical installation, you must ensure access, information, transparent pricing, ad hoc charging, payment, connectivity, interoperability, universal accessibility, data communication and maintenance.
Should you always install the maximum possible power?
No. Oversizing can increase the cost of the service connection, contracted power and works without improving operations. The best installation is the one that delivers the required kWh before departure and can grow in an orderly way.
