All FAQs
NMC: No (limit to 80-90%). LFP: Yes (weekly). Always consult the vehicle manual.
Minimal impact on modern liquid-cooled batteries, though frequent supercharging in extreme heat can accelerate degradation over long periods.
Warming the battery before reaching a fast charger. This ensures the battery is at optimal temperature to accept maximum charging speed immediately.
The Battery Management System (BMS) reduces current to prevent overheating and chemical damage as the battery nears saturation (the charging curve).
kW is the speed (flow). kWh is the quantity (capacity). You wait for kW; you pay for kWh.
Penalties charged for leaving a vehicle plugged in after the session has ended. They are a tool to reduce congestion at public chargers.
Penalties for occupying a station without charging (ICEing) or for "hogging" a high-demand station unnecessarily (e.g., charging to 100%).
It slows down chemical reactions (reducing capacity) and requires energy for heating. Range can drop by 20-30%, and charging speeds slow down.
It delays charging so the battery reaches 100% just before departure, minimizing the time the battery sits at high voltage/stress.
The Charge Point Operator (CPO) manages the physical infrastructure and technical operations (installation, maintenance). The Mobility Service Provider (MSP) manages the customer relationship, providing the access card/app and handling billing.
They interact via roaming agreements using protocols like OCPI. Commercially, the CPO charges the MSP a B2B rate, and the MSP resells this to the driver with a margin.
Roaming allows drivers to charge at stations not owned by their MSP. Hubs (e.g., Hubject) act as clearinghouses, connecting thousands of CPOs and MSPs through a single connection.
A White Label solution allows a company (e.g., a utility or leasing firm) to offer branded CPO or MSP services without developing their own proprietary technology stack.
CPOs typically use pseudo-anonymous IDs (EMAIDs) to authorize sessions, ensuring they do not store the driver's personal data. MSPs aggregate this data for billing and insights.
Revenue streams include direct sales (ad-hoc), B2B roaming fees charged to MSPs, parking/blocking fees, and Hardware-as-a-Service (HaaS) contracts.
Pricing models include Pay-as-you-go (markup), Subscription (monthly fee for lower rates), Flat Rate bundles, and increasingly Dynamic Pricing based on grid demand.
The CDR is the data receipt generated after a session containing kWh, time, and ID data. It is the basis for billing between CPO and MSP.
It ensures different cars, chargers, and backends work together. The industry relies on open standards like OCPP and OCPI to prevent proprietary "walled gardens."
Aggregators bundle the charging load of many EVs to sell flexibility and demand-response services to the grid, rather than just selling access to drivers.
AC Charging uses the car's on-board charger (slow, 7-22kW). DC Fast Charging uses the station's converter to bypass the car's limit (fast, 50-350kW).
Regional standards evolved differently. Type 2 is the EU AC standard. CCS is the EU DC standard. CHAdeMO is a legacy Japanese standard being phased out in Europe.
A 3-Phase cable supports up to 22kW (tripling speed) and is backwards compatible. A 1-Phase cable limits charging to 7.4kW. 3-Phase is recommended for future-proofing.
Unlock the vehicle repeatedly, ensure the session is terminated, push the cable in to relieve tension, or use the emergency manual release cable in the car.
Requirements often include non-combustible mounting surfaces, collision protection (bollards), and integration with fire detection systems to cut power (shunt trip) if smoke is detected.
It is legislation that prevents building management from arbitrarily denying tenants the right to install EV charging infrastructure at their own expense.
To determine if the existing grid connection can handle the high continuous load of an EV charger without blowing main fuses, and to see if Load Balancing is needed.
Tethered has a fixed cable (convenient). Untethered has a socket (flexible, durable, standard for public use to reduce vandalism).
AC chargers last 5-10 years. Wear parts include contactors and locks. DC chargers require more maintenance (filters/coolant). Software updates are critical for longevity.
High heat (>35°C) can cause stations to derate (slow down) output to protect electronics. Cold can make cables stiff and screens sluggish.
Split billing separates EV charging costs from home energy bills, allowing employers to automatically reimburse employees for business charging based on meter data.
In Belgium, rates are often benchmarked against CREG (regulator) average tariffs to ensure reimbursements are fair and tax-compliant.
Smart Station: Fixed wallbox with meter. Smart Cable: Portable cord with inline meter, allowing split billing from standard sockets.
An EU regulation mandating targets for infrastructure coverage, price transparency, and ad-hoc payment methods across Europe.
New DC chargers must have card readers. New AC chargers must have dynamic QR codes or card readers to enable payment without a subscription.
A standard enabling automatic authentication and payment via digital certificates just by plugging in the car, eliminating apps and cards.
QR-code phishing scams. AFIR mandates dynamic QR codes (on screens) to prevent criminals from pasting fake stickers over static codes.
They combine charging, solar, and battery storage to meet AFIR speed/coverage targets even in areas with weak grid connections.
CPOs must ensure CDRs contain accurate data for VAT calculation. B2B roaming often uses the Reverse Charge mechanism.
It forces fleets to electrify. Capabilities like Split Billing become operational necessities for reimbursing home charging costs for employees.
Static reserves a fixed amount of power for EVs. Dynamic monitors real-time building usage and allocates all remaining capacity to EVs, maximizing speed.
The charger monitors grid export. If the home exports excess solar power (e.g., 3kW), the charger matches this rate to charge the car with 100% free, green energy.
A software-only solution that estimates solar production via weather data to optimize charging without requiring a physical data connection to the solar inverter.
A grid fee based on peak power usage (kW). It forces the adoption of smart charging to spread consumption and avoid costly peaks on the energy bill.
V2G allows EVs to discharge battery energy back into the grid to stabilize frequency or absorb renewable peaks. It requires bidirectional hardware.
V2H allows the EV to power the home directly during blackouts or peak tariff hours. It operates "behind the meter" and requires an islanding switch.
An EMS is a central controller that orchestrates EVs, heat pumps, and batteries based on solar production and grid tariffs to optimize cost and comfort.
Yes, but it requires a grid-forming inverter and a battery buffer to provide the stable voltage and frequency reference the charger needs.
The standard minimum is 6 Amps (approx. 1.4 kW). Solar charging sessions must pause if production drops below this threshold.
