Maintenance

Charging station can be maintained and repaired by qualified personnel only.

Charging station’s power supply should always be switched off during the maintenance and repair.

Avoid hazardous risks. Only the manufacturer, an authorized service technician, or technically qualified personnel may replace damaged charging station or its components.

Fire Safety Measures

At the location of car charging, the fire hazards and thus the threats are increased during the process of charging. The overall design of our products is made on the basis assumption that the fault could occur on any element of the system. Either in the electrical wiring of power supply, in wiring or inside of the charging station, or in the car.

The enclosure and the assembly design of the charging station are made in such a way that the contact of the user to hazardous parts is not possible. In the event of fire, metal enclosure would constrain a fire and would not allow the propagation outside of the enclosure. Regarding the fire safety in all possible cases of installation, that are out of control of our company, several recommendations are listed:

The charger must be installed outside the hazardous area.

The installation of the charging station can be performed only by professional electrician and must comply with the installation manual and local installation rules.

Ensure that there is enough space to manoeuvre vehicles into their designated charging areas and that in event of fire the escape and rescue routes are not obstructed.

No flammable or combustible material should be stored within the charging area.

Provision of suitable portable fire extinguisher at the location of the charging station is proposed.

Firefighting Measures

CHARGING STATION FIRE

In the event of a charging fire, the usual rules in the event of an electrical cabinet fire apply. In case of fire please follow these steps:

In the event of a fire, immediately stop using the charging station and call the appropriate services (fire brigade).

If possible, disconnect the station from the power supply by pressing the fire protection switch (if present) or another switch responsible for cutting off the power supply to the station.

Retreat from fire area.

Extinguishing should be carried out with extinguishers intended for extinguishing electrical devices up to 1000 V.

Do not extinguish live electrical installations and devices with water!

The following is general information obtained from various sources. For detailed instructions on extinguishing fires of electric vehicles or their batteries, fire brigade have appropriate procedures already established.

Vehicle Fire

Vehicles, made of light metal, such as magnesium or aluminium, develop high temperatures above 1000 °C when burning. When extinguished with water such a high temperature evaporates it and can cause burning particles of distinctly white colour and high temperatures to fly around the vehicle. Extinguishing such vehicles requires great care in forming the water jet and in the amount of water.

If a burning vehicle is connected to a charging station, it is necessary to ensure that the charging station is in a voltage-free state by disconnecting the line from which it is supplied.

If firefighters are at the scene of a fire in less than half an hour, the battery usually does not ignite yet and the vehicle can be extinguished easier, and all extinguishing agents can be used. The general recommendations are mainly to use water and foam.

Battery Fire

In general, battery manufacturers, regardless of the type of battery, recommend water for successful extinguishing, although reactions may occur.

If the batteries catch fire, they will burn until they burn out completely. Another option is to immerse the batteries in water for at least half an hour. If the battery is not extinguished successfully, the fire will recur.

Environmental Safety Measures

When implementing protection measures, environmental protection must also be observed. For this reason, special care has been put into selection of the components and their compliance with the Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS). This directive restricts use of hazardous materials in the manufacture of various types of electronic and electrical equipment.

The substances banned under RoHS are heavy metals, lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates (DEHP, BBP, DBP, DIBP).

The restricted materials are hazardous to the environment and pollute landfills and are dangerous in terms of occupational exposure during manufacturing and recycling.

Another example of use of environmentally friendly materials in our products is compliance to REACH, which is a regulation of the European Union, adopted to improve the protection of human health and the environment from the risks that can be posed by chemicals. REACH regulation also promotes alternative methods for the hazard assessment of substances to reduce the number of tests on animals. Packaging of our products is environmentally friendly and materials degradable.

Design Considerations

Special care has been put into selection of components and materials and their compliance to requirements set in standards, technical directives, and rules of good practice.

The internal wiring was carefully designed, and the propriety of whole assembly thoroughly evaluated. Basic design considerations include voltage, insulating materials, time under voltage stress and degree of pollution at the location.

Creepage distances, clearance between circuits and spacing to metal enclosures are important requirements for insulation coordination. Thus, calculation and measurement of clearance and creepage distances, in accordance with requirements, are one of the significant parts in design of our products. They are dimensioned to withstand the required impulse withstand voltage and to withstand the long-term continuous operation.

A charging station operates with an RCD device, which is designed to protect against the risks of electrocution and in addition offers protection against fire caused by earth faults. It is a sensitive safety device that switches off electricity automatically if there is a fault.

The ingress protection class of IP54 proves, that the enclosure of the charging station is protecting the internals against ingress of solid objects, permits only limited ingress of dust and is protected against water splashes from all directions. Impact protection, of at least IK08 states, that the charging station can withstand impacts, equivalent to 1.7 kg dropped from height of 30 cm. As required, tests for the IK class were performed before testing of IP class.
