Description

The technical solution concerns the fields of energy (batteries, production of electricity from renewable sources) and automotive (charging of electric vehicles).

BACKGROUND OF THE INVENTION

In the current period (2015), electric and hybrid cars are increasingly being produced and promoted. Electrically powered cars with a source of electricity stored in the batteries installed in the car currently range between 100 and 500 km and require battery charging. The range depends on the technical solution, the batteries used in the car and, last but not least, on the outside air temperature.

Due to its length and availability, battery charging is currently the weakest point of this environmentally friendly mode of transport. Charging time to full battery capacity is up to 8 hours, while charging to 80% capacity, this time can be shortened to approximately 20 minutes, depending on the installed battery capacity and charging method (single charger or dual charger, alternating or direct current). In terms of availability, it is possible to carry out charging mainly in homes or business premises at night. When traveling depending on the installed capacity, one accelerated charge of up to more accelerated charges to 80% of the capacity is required for longer journeys. The network of installed charging stations in Europe is relatively thin, even smaller in the countries of Central and Eastern Europe.

Another developing option is the replacement of discharged batteries, eg. at gas stations piece by piece, which is associated with building the necessary demanding infrastructure.

The disadvantage of systems is that the design of the device itself can be costly; devices also do not have a solved billing system, thermal regulation, or fire-fighting system.

The essence of the technical solution

This deficiency can be completely eliminated by the device according to the present invention. The advantages of this solution are mainly:

- absence of a classical building permit process

- quick installation and commissioning of the charging station - approx

- portability of the entire container to a potentially higher-use location

- unattended operation

- promoting an environmentally friendly mode of transport together with an environmentally friendly production of electricity

Figure 1 shows a typical external configuration of a portable charging source; Figure 2 is a plan view of the interior of the portable charging source; and Figure 3 is a schematic diagram of portions of portions of the portable charging source.

EXAMPLES

A portable electric vehicle charging source is installed in a portable container 1 (eg a shipping container) together with the batteries 5 as a source, the recharging of the batteries 5 is ensured either from renewable sources (photovoltaic panels 4.1 installed on the folding roof 4 and walls of the portable container 1); wind turbines 4.2), or by connecting to an existing power grid in the vicinity or in the vicinity. a combination of renewables and electricity. The batteries 5 in the portable container 1 are preferably recharged from renewable sources and only when a higher capacity is needed will an external power connection be used for charging.

The whole solution consists of the following components:

A portable container 11 as a base for deploying technology

- Photovoltaic cells 4.1 and wind turbines 4.2 as a source of electricity on the folding roof 4 Batteries 5 for storage of energy Inverter 8 (inverter) for DC / AC current Heating and ventilation system 10 Control unit 6 for measurement and control Fire-fighting system 9

Charging sockets 2a for charging batteries 5 of the portable container 1 and charging sockets 2b for charging electric vehicles

Billing and Payment System 7 via SMS Touch Information Panel 11 and Operator Monitor 3

A portable container 11 (e.g., a shipping container) is contemplated in 2 modular sizes, larger - 40'DC with dimensions wxhxd 2438 x 2895 x 13556 mm for an external power source independent, and smaller size - 20'DC with dimensions wxhxd 2438 x 2591 x 6058 mm for a combination of renewables and an external network connection in places where it is available.

The abbreviation DC / DRY FREIGHT CONTAINER STEEL / determines its type classification, ie the container is steel and is intended for storage or transport of dry and solid goods and materials.

SK 7548 Υ1

Photovoltaic cells 4.1 are considered with electrical power (> 280 W / m ² ) and installation on the entire folding roof 4 of the portable container 1 and on the side wall parts (total 30 - 60 m ² depending on the type of portable container 1). The installed capacity will be 6 to 12 kW.

Wind turbines 4.2 are considered as an additional source with power up to 3 kW.

The batteries 5 for storing the generated electricity provide for stackable batteries 5 located inside a portable container 11 with a capacity of 400 to 900 kWh. The operating temperature of the batteries 5 is assumed to be -5 ° C to 40 ° C, at lower temperatures the portable container 1 is electrically heated, and at higher temperatures it is ventilated. The batteries 5 are replaceable and allow at least 10 electric vehicles to be charged at full capacity.

Inverter 8 (inverter) for DC / AC - only required for electric vehicles charged by AC power.

The measurement and control unit 6 regulates and controls the charging process itself and at the same time performs the billing measurement.

The charging station has installed min. 2 most commonly used types of connection sockets 2b for charging electric vehicles, namely:

- 2 pcs alternating current IEC 62196-2; Europe pc type one-way IEC 62196-3; Europe

The billing and payment system 7 is implemented by a non-cash SMS on-line payment system. Using the free download application on the mobile phone, the customer enters the required amount of electricity consumed by the default number and sends an order and agrees to pay for that amount by sending an SMS. The amount of the payment based on current prices will be determined by the application, which also signals the nearest available charging station to the driver. SMS is processed internally (via mobile carrier, aggregator and mobile payments platform), then the transaction is authorized. If the transaction is successful, the billing and payment system 7 will also send the access code and the invoice again to the customer via SMS. Alternatively, this service sequence can also be performed on the touch panel 11 located on the portable container 1 and payment is again made via SMS. After connecting to the electric car charging socket 2b and entering the appropriate access code, the control and measuring unit 6 starts the electric vehicle charging process itself - the transmission of the ordered and paid amount of electricity.

Operation of the device is provided automatically by a computer-based measurement and control unit 6 operating system, which is located inside the portable container 1 and which is connected to other devices via a network and standard communication protocols. The measuring and control unit 6 controls and records the necessary data from all the devices and enables the connection of a touch-screen information panel 11, which also serves the customer service.

At the same time, the control and measuring unit 6 also signals possible faults of some of the devices or the system as a whole.

Industrial usability

Industrial utilization lies in the deployment of containers on the crucial road routes in the locations of existing service stations or also in places of rest stations, resp. parking lots of large retail chains, where the devices would be based on a simple SMS payment to recharge the batteries of electric vehicles.

The advantage of the present solution is the flexibility, mobility and modularity of such sources and their very quick installation, without the need for a complicated authorization process. At the same time, the device is modular in terms of source size (container type) and in terms of output size (depending on the number of batteries and the number of photovoltaic panels and wind turbines installed).
