1 based vehicles in the next decades


For this
project, the goal is to implement a new system in the out coming electric cars
in order to compensate the power loss that occurs when charging and discharging
the vehicle, which is approximately 16%. Electric cars have been impacting the automobile
market in the last years and it is estimated that most petroleum cars will be
replaced by electric vehicles in the next decade. In order to provide a better
product, a new system must be implemented to make up for energy losses, making
it possible to provide an even better product for the users of this specific
kind of vehicles. To be able to deliver a better efficiency, energy should be
conserved as much as possible without the risk of losing it while doing simple
tasks such as charging the vehicle or shutting down the engine. This new system
should comply with the governmental regulations established for the automotive industry
and be available to all EVs for the next decade.

Business or Mission Analysis Process

The mission of this new system is to
compensate the energy loss of an electric car when the user is charging the
vehicle or the car is off. By compensating the energy loss, we guarantee that
the clients will be satisfied with the overall battery life of their vehicle. If
this system is implemented, the price of the vehicle will rise initially, but
it will be recompensed to the users through a longer battery life cycle, avoiding
a higher electricity bill in the long term and obtaining a fully charged car in
less time. With the proposed new system, electric vehicles will have a better overall

1.1.1     Define the business or mission
problem or opportunity

Electric vehicles are more expensive
that simple petroleum efficiency cars, and for this reason, they should provide
more than one advantage to the users. These particular sets of cars have impacted
the automotive industry around the world for its environmental benefits. Some
countries already have plans to eradicate all petroleum based vehicles in the
next decades with electric cars only, creating new business opportunities with
more potential clients around the world. With this reasoning, the product that
would be delivered to the user should be improved with the objective of
providing a high quality vehicle and economic savings in the long term. While
electric vehicles have improved greatly since their first launch, a clear example
of this improvement is the change of cobalt batteries into lithium ion, there
are a lot of improvements that could still be made. By the proposed system,
energy losses could be minimum without risking any safety factor. As it was
stated above, the price for this improvement will impact the initial price of
the vehicle, but it will be compensated to the user through a lower cost bill
on electricity.

1.1.2     Characterize the solution space

For this new system, the major
stakeholders are the customers that will buy and use the product, as well as
automotive organizations that have interest in electric cars, such as Tesla
Motor. Governments interest in continue giving or creating new electric
vehicles incentive programs are also key stakeholders that have to be taken
into consideration. In order for this system to be feasible, governmental
regulations in each geographic area where the SO will be implemented should be
taken into consideration.

1.1.3     Determine potential solution

Implement solar panels in the vehicle to
compensate the energy lost during the DC-AC conversion process. It has to be
noted that in order to obtain the most of the solar panel, the user should
consider charging the car during sunlight. The fact that new improved technologies
may arise in the future years should be taken into consideration, as there is a
risk that this system could be impacted by it.

This new system can be implemented by
any EV company and any buyer/user of this specific sort of vehicles.

1.2       Business Purpose

The reason of changing the current methods
used when developing EV by introducing solar panels into the process is because
of the relatively short period of time the charge on the battery of the vehicle
last, creating an concern for the user. It is in the interest of users and EV companies,
that this issue is resolved by providing a new alternative in preserving the
energy. By implementing this new system when developing the EVs, the
stakeholders have the reassurance that the percentage of energy lost while
doing simple tasks will be reattributed by the energy that the solar panel will

Business Scope

vehicles launching on the next decade will have a series of solar panels that
will be used as an energy source when the energy of the vehicle decreases while
users charge the vehicle, making it faster to obtain a fully charged car and
compensating the percentage of energy lost during this task.

Business overview

The application of solar panels will extend the life of the
vehicle battery. We can provide a better battery efficiency and most important,
a better vehicle.

1.6.1     Validation Criteria

By applying solar panels in EV, there
will be another source to store energy on the battery, so when the user decides
to charge the EV, the power won’t decrease. The loss of energy occurs within
the 3 step process of converting chemical energy (lithium ion) into electrical
energy which will then transform into kinetic energy. Because solar panels
generate electrical energy by using sunlight as a source, the energy lost in
the DC-AC conversion process will be negligible. It is understood that the car won’t
perform by using solar panels, they will merely be a source of energy when the
power decreases during the energy conversion. By implementing this system, the
vehicle still has to be aesthetically pleasing. Safety is always a priority, so
it should not be compromised.
