• INTRODUCTION
• A lot of basic concepts, technologies and pioneering solutions
aiming on very high power densities were mainly developed
within the last 20 years. Sometimes this is denoted as the
mechatronic system integration or simply as mechatronics.
Besides many of the technical aspects, the movings within the
value chain represent the great challenge in this process. This
is because traditionally defined between electronic device and
the power module manufacturers, electronics assemblers, and
the metalworking industry will blur or slowly disappear.
However, the pressure to go this path increases. If one thinks,
e.g., about the hybrid drive as an upgrade option for
conventional passenger cars, one is directly faced with the
lack of construction space as one of the main serious
problems (Alkuhayli et al., 2012).
• This high- voltage power net encompasses at least an
electrical energy storage and the single drive inverter. Most
different vehicle concepts exist that comprise further the power
electronic sub-systems connected to the high voltage bus, like
e.g. a DC/DC converter for supplying the low-voltage power
net (as the replacement of the conventional 14 V generator),
an inverter for the electric climate compressor, a DC/DC
converter for stabilizing the traction bus voltage, or the AC/DC
converter as an uni- or bidirectional vehicle to grid interface.
The high-voltage power net must be specifically and
galvanically isolated against the low-voltage net and the
vehicle chassis on the safety reasons, and the HV harness
generally requires the shielded cables and connectors
(Adefarati et al., 2016).
• .
• SYSTEM PARTITIONING
• Considering the various power electronic subsystems necessary in the EVs or
HEVs, the question arises how to set-up and/or mainly integrate these
subsystems, i.e. how to partition the whole system. Many options exist with
respect to this. The major common solution today is to integrate all the power
electronics in a central box. The pros of a comparatively simple set-up is
contrasted with the cons of a separate expensive housing that is quite bulky and
thus difficult to integrate in the engine compartment of the existing passenger
cars. Another decisive disadvantage is that a lot of the expensive shielded high-
voltage connectors and cables are necessary from the box to all of the various
loads.This arrays follows the basic idea of the "site-of-action integration" and
minimizes the high voltage cable harness. Each drive inverter is integrated into
or attached to the electric motor it mainly operates. Any converter necessary for
electrical energy management,the power supply or charging is integrated into the
energy storage that becomes the smart battery unit by this way (Bansal et
al.,2008).
• OVERVIEW FOR DESIGN OF SYSTEM
• Solar - wind hybrid system suits to the Kenyan conditions where sunlight and
wind has in most cases non-seasonal but the experience shifts . In the parts
proposed in Kenya, wind does not blow throughout the day but the sun does
shine for almost the whole entire day
• Therefore, the hybrid arrangement of combining the power
harnessed from both the wind and the sun and stored in the
battery can be a much more reliable and realistic power
source. The load can still be powered availing the stored
energy in the batteries even when there is no sun or wind.
Hybrid systems are built for the design of systems with
maximum reliability . Though, the high cost of the solar PV
cells makes it less competent for larger capacity designs, the
wind turbine comes in the cheaper cost as compared to the
PV cells. Battery systems are required to store solar and the
wind energy produced during the day time. During the night
time and even some day time, the presence of wind is an
added advantage, which aggrandizes the reliability of the
system (Khare et al.,2016).
• CONCEPTUAL DESIGN
• Photovoltaic solar power
• Solar panels of medium size were availed to convert solar energy into the
electrical energy. Solar panels can convert the energy directly or heat the water
with the major induced energy. Photo-voltaic cells availed are those made up
from semiconductor structures as in the computer technologies . Sun rays are
absorbed with this material and the electrons are emitted from the atoms .This
release activates a current. Photovoltaic is the known as the process between
radiation absorbed and the electricity induced. Solar power is mainly converted
into the electric power by the common principle called photo electric effect. The
solar cell array or panel consists of an appropriate number of the solar cell
modules connected in series or the parallel based on the required current and
voltage (Liu et al.,2016).
• Batteries
• The batteries availed in this hybrid system were providing to store the electricity
that is generated from the wind or the solar power. Any required capacity can be
obtained by the serial or the parallel connections of the batteries. The battery
that provided the most advantageous operation in the solar and the wind power
systems are maintenance free dry type and utilizes the specia electrolytes
(Čepin,2011).
• Inverter
• Energy stored in the battery was drawn by the electrical loads through the
inverter

  • 4. • SYSTEM PARTITIONING • Considering the various power electronic subsystems necessary in the EVs or HEVs, the question arises how to set-up and/or mainly integrate these subsystems, i.e. how to partition the whole system. Many options exist with respect to this. The major common solution today is to integrate all the power electronics in a central box. The pros of a comparatively simple set-up is contrasted with the cons of a separate expensive housing that is quite bulky and thus difficult to integrate in the engine compartment of the existing passenger cars. Another decisive disadvantage is that a lot of the expensive shielded high- voltage connectors and cables are necessary from the box to all of the various loads.This arrays follows the basic idea of the "site-of-action integration" and minimizes the high voltage cable harness. Each drive inverter is integrated into or attached to the electric motor it mainly operates. Any converter necessary for electrical energy management,the power supply or charging is integrated into the energy storage that becomes the smart battery unit by this way (Bansal et al.,2008). • OVERVIEW FOR DESIGN OF SYSTEM • Solar - wind hybrid system suits to the Kenyan conditions where sunlight and wind has in most cases non-seasonal but the experience shifts . In the parts proposed in Kenya, wind does not blow throughout the day but the sun does shine for almost the whole entire day
  • 5. • Therefore, the hybrid arrangement of combining the power harnessed from both the wind and the sun and stored in the battery can be a much more reliable and realistic power source. The load can still be powered availing the stored energy in the batteries even when there is no sun or wind. Hybrid systems are built for the design of systems with maximum reliability . Though, the high cost of the solar PV cells makes it less competent for larger capacity designs, the wind turbine comes in the cheaper cost as compared to the PV cells. Battery systems are required to store solar and the wind energy produced during the day time. During the night time and even some day time, the presence of wind is an added advantage, which aggrandizes the reliability of the system (Khare et al.,2016). • CONCEPTUAL DESIGN
  • 6. • Photovoltaic solar power • Solar panels of medium size were availed to convert solar energy into the electrical energy. Solar panels can convert the energy directly or heat the water with the major induced energy. Photo-voltaic cells availed are those made up from semiconductor structures as in the computer technologies . Sun rays are absorbed with this material and the electrons are emitted from the atoms .This release activates a current. Photovoltaic is the known as the process between radiation absorbed and the electricity induced. Solar power is mainly converted into the electric power by the common principle called photo electric effect. The solar cell array or panel consists of an appropriate number of the solar cell modules connected in series or the parallel based on the required current and voltage (Liu et al.,2016). • Batteries • The batteries availed in this hybrid system were providing to store the electricity that is generated from the wind or the solar power. Any required capacity can be obtained by the serial or the parallel connections of the batteries. The battery that provided the most advantageous operation in the solar and the wind power systems are maintenance free dry type and utilizes the specia electrolytes (Čepin,2011). • Inverter • Energy stored in the battery was drawn by the electrical loads through the inverter
