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:

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:

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 IP56 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 IK10 states, that the charging station can withstand impacts, equivalent to 5 kg dropped from height of 40 cm. As required, tests for the IK class were performed before testing of IP class.

INSTALLATION PROCEDURE

OPERATION AND CHARGING PROCEDURE

First Power up

Before starting the station, it is absolutely necessary to read this manual and the technical specification of the device.

When the charging station is power up for the first time it can take several minutes for station to get ready to start using it to charge EV. Charging station is powered up automatically when it is connected to the electricity. In the table below, all possible events that can occur at the power up of the station are listed with the procedure what to do in case something is wrong.

First Charging Session

Check Whether the Charging Station is Working Properly and Setting of Maximal Charging Current

When the charging station has either overcurrent or RCD protection installed, check whether the protection element is in ON position.

Connect charging station to the power supply in the electrical cabinet. Installation feeder should be turned on.

The default value is 16 A and it can be set in range of 6 A to 32 A. Information of the current value is obtained with short press on the key. Number of short beeps represents information of set maximal charging current (number of beeps x 2 A).

Settings can be accessed with key press for more than 5 s. After that, a long beep is a notification that the settings can be changed. Each short press on the key increments the maximal charging current by 2 A, from minimal value of 6 A. E.g., to set 24 A, the key should be pressed 9 times.

To save the settings, press the key for more than 5 s. Long beep is a confirmation that settings were saved, two short beeps are a warning that settings were not saved.

Regular MAINTENANCE

Etrel charging station does not require any periodic maintenance. However, it is recommended to perform a visual check and test of the protection elements once per year.

Detailed descriptions of security checks and their intervals are included in the service manual.

Reset and Test the Protection Elements

Overcurrent Protection

Check the overcurrent protection (if installed) once a year for any visible damages on the surface. If the overcurrent protection is tripped and the switches cannot return to the active position something is wrong with the protection and needs to be changed by maintenance crew.

Surge and Overvoltage Protection

Check the surge and overvoltage protection (if installed) once a year for any visible damages on the surface. If the surge and overvoltage protection is tripped it needs to be changed by maintenance crew.

RCD

The regulations require that residual current protective device (RCD) is tested regularly, and an audit log should also be kept. The test button on the RCD unit allows user to verify the correct operation of the device by passing a small current through the RCD unit. This simulates a fault by creating an imbalance in the sense coil. If the RCD does not trip when this button is pressed, then the device must be replaced by licensed electrician. The device must be changed also when the RCD was tripped but the switch cannot be moved back into active position. RCD testing must be completed every three months and documented.

TROUBLESHOOTING

Errors dangerous to device users:

Dangerous voltage present on enclosure or device under fire. In this case the device should be turned off immediately. Switch off device power supply of device in the distribution board from where device is supplied and not on device itself. Do not touch device. If vehicle is connected at that moment, disconnect plug from the vehicle and not from the charging station, but only after the power supply was switched off. In the case of fire use fire extinguisher appropriate for electrical fire.

Faults occurred because of external conditions:

Undervoltage, overvoltage, short and long power supply outages or wrong vehicle behaviour. In these cases, no action is needed to re-establish normal operating conditions. Once fault is gone, normal operation conditions will be established automatically. If temporary fault was caused by vehicle, user will have to reinitiate charging session.

Device hardware failure preventing normal operation:

Example: Broken socket, electronics failure. If after restart device does not start normally, contact supplier support.

Charging station software failure:

Check that latest version of firmware is running on the charging station. If the latest version is installed and problem persist, then check if problem is caused by the charged vehicle. To check this, the charging could be tried on another charging station. If problem is not in the vehicle send diagnostic logs to the supplier.

Access to the Maintenance Area

Etrel INCH LITE charging station provides quick access to the side maintenance area to execute basic troubleshooting and to reset the charging station in case there are some problems.

Side maintenance area is protected by the side maintenance doors. Depending on the type of Etrel INCH LITE charging station, two different doors are available. One with the regular key lock and one with hex screw (2.5 mm). To access the area, either key or a hex screwdriver is needed.

Figure 7: Doors with keylock Figure 8: Doors with hex screw

There is a sticker on the inside of maintenance doors, with technical information including basic charging station information, model type and serial number. When support is contacted it is important that the charging station model type is known so the support can quickly help solve the issue.

Reseting the Charging Station

Charging station can be reset by opening the side maintenance doors and pressing the button inside the maintenance opening.

After holding the button for 4 s, the charging station will respond with the beep after which the options on the screen to check the IP address of the station or to reset the station will be presented. Basic reset and factory reset, which will restore charging station’s factory settings (username, password, default IP and other settings) can be made.
