Electric chargers

What is a recharge point or Wallbox?

Although they are also called "chargers", technically they are Electric vehicle feeding equipment (SAVE). The real charger is inside the car; the Wallbox It is the intelligent device that manages energy delivery safely, protecting both the installation of your home and the chemistry of the battery of your vehicle.

Install a specific recharge point instead of using a conventional plug (Schuko) is vital for three reasons:

1. Speed: It allows up to load up to 10 times faster.

2. Security: Avoid overheating in the electrical installation of the house.

3. Savings: It allows to program the load in valley hours or use exclusively the surplus of your solar panels.

Types of chargers according to their power and speed

To choose the appropriate charger in Tienda Solar, it is essential to understand the load levels and how they affect your daily routine:

1. Slow charge (Level 1 - monophasic AC)

Use a standard household plug (2.3 kW). It is an emergency solution or for personal mobility vehicles (skaters, bikes).

• Estimated time: 18-24 hours for a full load.

2. Semi-fast charge (Sky 2 - AC Single / Three-phase)

It is the standard in homes and companies (7.4 KW in single-phase or 11 kW / 22 kW in three-phase). They are the acquaintances Wallbox.

• Estimated time: 4-8 hours It is ideal to charge the car during the night.

3. Fast and ultrafast load (level 3 - DC DCT)

High power equipment (from 50 kW to 350 kW) found in service stations and electrollers. They inject energy directly into DC to the battery.

• Estimated time: 20-40 minutes to reach 80%.

The revolution of self-consumption: Upload with the sun

On Tienda Solar We are specialists in integration Photovoltaic + Electric Vehicle. If you have solar panels, you need a charger with surplus management.

• How does it work? The charger communicates with the inverter Solar or by an amperemptric clamp. If your home consumes 1 kW and your panels produce 4 kW, the charger detects those 3 kW surplus and injects them into the car instead of pouring them into the network.

• Smart charging modes: Models like the Zappi or the Wallbox Press Max They allow you to choose between loading only with Sol (100% free), hybrid mode (SOL + network) or fast mode (maximum available power).

Types of connectors and compatibility

It is crucial to identify the "plug" that your vehicle uses. Although the market tends to standardization, there are several types:

• Type 2 (Mennekes): The European standard. It is the one that most current cars (Tesla, Renault, VW, Hyundai, etc.) use. Supports single-phase and three-phase load.

• CCS2 (Combined Charging System): It is a type 2 with two additional pins for fast charge in continuous current (DC).

• Chademo: Japanese standard (used in old models such as the Nissan Leaf). Less and less frequent in Europe.

• Type 1 (SAE J1772): Common in ancient American and Japanese vehicles.

Dynamic load rolling: prevents the "lead" from jumping

One of the most frequent doubts in Tienda Solar is: "Do I have to increase my hired power to load the car?". The answer is usually Not, Thanks to the dynamic rolling.

This system monitors the consumption of your home in real time. If you turn on the oven and air conditioning, the charger automatically lowers the power delivered to the car so as not to exceed the hired limit. When you turn off the appliances, the charger raises the power again. Safety and savings without changing your electrical contract.

How much does it cost to load an electric car in Spain?

The cost depends on where and when to load:

1. At home with solar panels: The cost is $ 0. It is the most profitable option.

2. At home with night rate (valley): The average cost is one of some € 0.10 - 0,15 € per kwh. Tour 100 km will cost you approximately € 1.5 to € 2.

3. In fast public loaders: The price goes up to € 0.40 - € 0.70 per kwh. It is still cheaper than gasoline, but reserves for long trips.

Comparatively, uploading an electric car at home is up 80% cheaper that fill a fossil fuel tank.

Installation and regulations (ITC-BT-52 technical instruction)

In Spain, the installation of recharge points is regulated by the ITC-bt-52.

• Community garages: You only need to inform the neighborhood community in writing; They can not prohibit the installation. Consumption is usually connected to your own housing counter.

• Single-family homes: The installation is more direct and allows integrating electrical protections (differential class A, surge protection) within the home box itself or in an auxiliary box next to the charger.

Frequently Asked Questions (FAQ)

1. Can I upload my car if it rains?

Yes, absolutely. The chargers of Tienda Solar They have certifications IP54 or IP55, which means that they are protected against water and dust. The connectors are designed to have no tension until the car and the charger confirm that the connection is tight and secure.

2. What maintenance does a Wallbox?

Maintenance is minimal. An annual visual revision of the cables is recommended and verifying that the electrical protections of the box work correctly by pressing the "Test" button.

3. Are there aid for the purchase of the charger?

Yes, the Moves III Plan In Spain it offers grants of up to 70% - 80% of the total cost of purchase and installation of the charger for individuals and autonomous.

4. Is a charger with a fixed hose or with jack (socket)?

The fixed hose It is more comfortable for day to day (reach and plug in). The Socket (Take) It is more versatile, since it allows you to connect any type of cable and it is more aesthetic if the charger is in a zone.
