Danish Sikkerhedsstyrelsen warns electric car owners from charging electric car in standard 230 V contacts. It reports several Danish media. Per Höjevik, head of the Swedish National Electrical Safety Board, confirms that there is a risk of fire.
– This is a relevant warning. You should be aware of the risks before starting to recharge their electric car, he said.
He says that the 230 V contacts of the household, so called Shuko connectors, it is not designed to withstand continuous load for a long time. The tested to withstand approximately 20 Ampere hour. But to fully charge the battery in an electric vehicle may need 16 amps for six to eight hours.
– If you have new, fine Contacts so maybe it is great, but the big problem is that the contacts wear. Then contacts may be heated and begin to digest, says Per Höjevik.
He was not aware of any fires caused by electric charge in Sweden. But the electric car country Norway, there have been several incidents, for example, began electrical installation in a hall to burn when the family loaded electric car. The reason was that a joint in the house’s electrical system could not handle the high current.
– Full electrical installation must withstand load, both the cabling and connector says Per Höjevik.
He introduced last year, the report “Information requirements concerning electrical safety around the charging infrastructure for electric cars,” a report commissioned by the government. Where discourage authorities from using Shuko plug for charging electric vehicles, because of the fire risk.
– I think that instead to use so-called Mode 3 charger, also called wallbox or charging box. It monitors the charging and switches off power to the vehicle if something goes wrong, he says.
