All you need to know about car chargers
What is Wallbox?
The term Wallbox refers to the charger that supplies electricity to the vehicle connected by a cable and a connector. This device, powered by alternating current, either in single-phase or three-phase mode, brings together several components that make it a charging system for your vehicle, also called SAVE (electric vehicle power system).
How much does it cost to charge a car?
The cheapest is to load vehicles in the most economical periods, that is, between 1:00 and 7:00. Anyway, the cost of charging an electric car depends fundamentally on two factors: the contracted values and the battery capacity of your electric car.
In general, each kWh has an average price that varies between € 0.15 (night) and € 0.25 (day). Therefore, to calculate how much a full battery recharge would cost, multiply the price of each kWh by the number of KWh your battery has. For example, the 2020 Renault ZOE, whose battery is 53 kWh, fully charged at night would cost approximately € 7.95, but doing so in the least economical period would cost € 13.25. In the case of ZOE, a charge allows you to cover approximately 400 km, so you would hardly spend € 3.35 / 100km.
What is the true autonomy of electric cars?
In Europe, the autonomy of electric cars is governed by the WLTP (Worldwide Harmonized Light Vehicle Test Procedure). This system is more demanding in the consumption register than the previous standard, which is why the indicated autonomy data is more reliable. However, despite the improvements it can be said that the real autonomy of an electric car is about 20% less than the approved one.
How long does it take to recharge my car? How can I calculate that?
Each manufacturer defines the type of technology it includes in commercial vehicles and, accordingly, the electrical power absorbed during charging depends on these characteristics.
To calculate the recharge time of an electric vehicle, just know the battery capacity in kWh, the maximum absorbed power and the charger power in kW.
For example, to calculate the charging time of a Renault ZOE from 0 to 100%, with a 53kWh battery, in a three-phase AC wallbox of 22kW, just make the calculation 53/22 = 2.4 hours charging 100%. In a fast charging station (PCR) in DC, this calculation can only be done from 0 to 80%, this is because the batteries accept less power from 80%, that is, in a 50kW DC PCR the same ZOE, it takes ( 80% x 53 kWh) / 50 kW = 0.85 hours or 51 min charging 80% of the battery, for about 320km of autonomy.
How am I contributing to the environment?
The electricity needed to charge the batteries of electric vehicles can come from several sources, including zero-emission sources, such as wind, solar and water.
In this sense, we also offer photovoltaic production solutions to help you reduce your energy bill and load the vehicle and thus contribute to a better quality of the air we breathe, to reduce the emission of greenhouse gases and at the same time to reduce energy dependency.
