ABNT (Brazilian Association of Technical Standards) published the standard ABNT NBR 17019:2022 – Low voltage electrical installations – Requirements for installations in special locations – Power supply for EVs (electric vehicles), prepared by the Brazilian Electricity Committee (ABNT/CB-003).
According to the association, ABNT NBR 17019 specifies the requirements for fixed electrical installations designed to supply electrical energy to electric vehicles and/or receive electrical energy from electric vehicles. The text was based on IEC 60364-7-722:2018.

According to ABNT, the standard does not cover the assessment of the risk of explosion due to the production of hydrogen, or other flammable gases, during battery charging. NBR 17019 replaces some sections of the NBR 5410 – Low Voltage Electrical Installations, which determines conditions and rules for low voltage electrical installations up to 1000 V in alternating voltage and 15000 V in uninterruptible voltage in Brazil.
The standard also contains definitions of what the charger for electric vehicles should be.
The text also determines that charging stations for electric vehicles intended for the public must be designed with easy access to the charging point in mind, in addition to being adequately signposted. Also according to NBR 17019:2022, the electric vehicle can be used as a backup source. However, the text contains observations:
- The definition of backup source according to NBR 5410 is as follows: power or source that replaces or complements the normal source;
- To use the electric vehicle as a backup source, it is recommended that you consult the vehicle supplier;
- Using an electric vehicle as a backup source does not exempt you from complying with the regulations of public bodies, regulatory authorities and electricity distribution companies.
Furthermore, in cases where electric vehicles are intended to supply power to the electrical installation, the requirements of IEC 60364-8-2 apply. The standard also recommends that a residual current circuit breaker (RCCB) be installed in the distribution board to ensure user safety.

NBR 17019 replaces some sections of NBR 5410.
I would like to know if the CURRENT LAW on the implementation of electric vehicle recharging will also apply to all condominiums and projects already approved prior to the Law?
Powered vehicles are a trend, but recharging processes have to keep up with demand….
We also need emergency procedures in case of an accident occurring at the charging location, such as: how to act safely in vehicle accidents at the location.
I would like to receive the PDF of nbr17019
An electrical project is necessary to install equipment for an electric car in a condominium.
THE ELECTRIC VEHICLE IS A BACKUP SOURCE IN THE EVENT OF A POWER OUTAGE AT THE HOME, BUT IT MUST BE ENTERED USING A REVERSING SWITCH INSTALLED BY A COMPETENT PROFESSIONAL TO AVOID AN ACCIDENT.
THE POWER SOCKET IN THE VEHICLE MUST BE WELL MADE AND HAVE SUFFICIENT CABLE.
THIS RESERVE MUST BE USED WITH A MARGIN OF SAFETY, WITH THE VEHICLE AND RESIDENCE IN MIND.
Cool.
Congratulations ⚡
Important points for installing a CHARGING STATION for ELECTRIC VEHICLES in a parking space in the CONDOMINIUM
Apparently it seems simple, but it's not!
Factors such as energy demand, consumption of each phase that feeds the apartment's QDF are some of the factors
that must be analyzed with criteria, it is not enough to just fix it on the wall and that's it, the protection circuits,
the voltage drop and many other factors are important for the electrical health of the installations, so a qualified professional
and prepared to know the customer's needs and characteristics of the electric vehicle is essential.
