Company EV charging: how to choose an EV charger for your business

For most companies the right choice is an AC wallbox rated at 11–22 kW on every regularly used parking space, combined with dynamic load management, RFID authorisation, and — at shared or publicly accessible points — a certified MID energy meter for accurate billing. Reserve DC fast charging only for places where vehicles stand briefly and must be ready quickly. This guide walks you through choosing a charger for your business step by step — from the type of operation, through the number of points and power, to the supplier.

If you are still wondering how to choose an EV charger for your business, don't start with the station model — start with who will charge and how. Everything else follows from that.

Step 1: Identify your type of company charging

Company charging is not a single scenario. Most firms combine several:

• Charging employee and pool vehicles on site — daily, during working hours or overnight. Typically an AC wallbox on a dedicated bay.

• Fleet depot — dozens of vehicles that return in the evening and leave in the morning. This requires load management so it doesn't overload the connection.

• Charging employees at home — a company car charged at the employee's home, with automatic metering and a basis for reimbursement.

• Visitors and semi-public points — a car park at reception, a store or a hotel, where external drivers also charge and authorisation plus invoicing are needed.

For a detailed comparison of what each category does, read our breakdown of how home, company and public stations differ. Here we go further — to the actual choice.

Step 2: AC or DC? For companies, dwell time decides

The key criterion is not "speed" but how long vehicles stand at your site.

• AC charging (11–22 kW) is the backbone of company charging. You recharge a car in 4–8 hours, which is more than enough when it stands through the working day or overnight. AC stations are cheaper, gentler on the battery and simpler to install.

• DC charging (50–400 kW) makes sense where a car must be ready within tens of minutes — logistics depots with short turnaround, shared cars, taxis, semi-public points by the motorway. DC is more expensive both to buy and in supply capacity.

We cover the difference between the two currents and when to use each in AC vs. DC charging: what is the difference. The vast majority of companies get by with AC; DC is for specific locations only.

Step 3: How many charging points and what power

Don't buy one point per car "just to be safe". Vehicles don't all stand at once, and dynamic load management lets you share one connection across several stations.

A practical starting guide:

Choose power based on the vehicles and the connection. Only a car with a three-phase onboard charger uses the full 22 kW; many cars charge at 11 kW at most. More important than the maximum of a single point is that the sum of the stations does not overload the main breaker — which is exactly what DLM handles.

Step 4: Load management (DLM) — don't underestimate it

Without management you would have to reinforce the connection (expensive and often impossible) or risk outages. Dynamic Load Management (DLM) distributes the available power between active stations in real time and respects the reserve for the building. We explain the principle in dynamic load management (DLM).

For a fleet it is essential: thanks to DLM you charge more vehicles on the existing connection without paying for a new supply. Stations such as the MyBox Profi (2×22 kW), combined with the superordinate MyBox ARM module, intelligently share the available power among themselves, so you can link up to 200 charging points at a single site.

Step 5: Metering and billing — when you need a MID meter

This is where companies most often go wrong. A certified (MID) energy meter is metrologically verified, and its reading is legally valid for invoicing. You need one as soon as you want to:

• re-invoice consumption to a third party (a tenant, a visitor, another cost centre),

• bill employees for charging, or conversely reimburse their home charging,

• operate a semi-public point with payment.

We explain why the higher price pays off in why a certified energy meter even though it costs more. For companies that bill, a MID station such as MyBox Plus is the obvious choice — it has a MID meter built into the configuration for company use, and it also suits reimbursing employees' home charging.

Step 6: Authorisation and access (RFID, QR, cloud)

A company station should not charge just anyone. An RFID card or QR code ensures only an authorised driver charges, and at the same time assigns consumption to a specific user or cost centre. A cloud platform (e.g. MyBox Cloud) then offers remote management, session history, reports and per-card limits. More on authorisation in the article on the RFID reader.

Step 7: Installation readiness and legislation

Before ordering, check the state of the electrical installation: the reserve on the main breaker, the distance from the distribution board and how the cables are run. Details are covered in preparing for charging station installation.

Watch the legislation too: for non-residential buildings and car parks with more than 20 spaces, since January 2025 there has been an obligation to provide charging infrastructure under § 167 of the Building Act and Decree No. 146/2024 Coll. (summary in our article). If you are building or renovating, include it in the project right away.

Step 8: Subsidies and payback (briefly)

Companies and the self-employed can obtain a contribution towards installing a charging station, on the order of tens to lower hundreds of thousands of CZK (roughly EUR 2,000–6,000 for smaller projects), and for larger projects — via the Modernisation Fund or regional and municipal calls — up to a high share of the costs. But the programmes change and allocations run out fast, so verify the current calls before ordering with the Ministry of Industry and Trade (MPO), the Ministry of the Environment (MŽP) and the National Development Bank. The economics of the whole operation (fuel savings, tax advantages, ESG) are covered in smart charging of company EVs: costs and ESG.

Step 9: How to choose a supplier

With company infrastructure, the station is only part of the solution. Ask about:

• a complete solution — design, installation, cloud and service under one roof,

• standards — Type 2 (AC) / CCS2 (DC) connectors, the OCPP protocol for independence from the backend,

• scalability — the option to add points and load management later,

• support and warranty from a Czech manufacturer with available service.

Quick summary by scenario

You solve company charging correctly when you start with the operation, not the catalogue. Define the scenarios, count the points with a reserve for load management, sort out metering and authorisation — and the station model then follows on its own.
