  Electricity is an essential comfort to support our daily activities. With the
competitive increase and energy costs by the industry, new values and
opportunities for delivering electricity to customers are produced. One of
these new opportunities is electric vehicles. With the arrival of electric
vehicles, various challenges and opportunities are being presented in the
electric power system worldwide. For example, under the traditional electric
power billing scheme, electric power has to be consumed where it is needed so
that end-users could not charge their electric vehicles at different points
(e.g. a relative's house) if this the correct user is not billed (this due to
the high consumption of electrical energy that makes it expensive). To achieve
electric mobility, they must solve new challenges, such as the smart metering
of energy consumption and the cybersecurity of these measurements. The present
work shows a study of the different smart metering technologies that use
blockchain and other security mechanisms to achieve e-mobility.
