Toyota Industries’ Technologies and Products Based on 3Es
Toyota Industries’ environmental technologies play a dynamic role in society and daily life.
We remain close to you and provide support for a comfortable society and enriched lifestyles.
Based on the keywords of 3Es (energy, environmental protection and ecological thinking), Toyota Industries
promotes the development of technologies that contribute to energy savings, electrification and lighter weight.
We are applying these technologies to our products in diverse business domains, including automobiles andmaterials handling equipment, and in turn contribute to the realization of a society with less environmental impact.

Toyota Industries’ Technologies and Products Based on 3Es

Leading the World in Energy-Saving, Electrification andLighter-Weight Technologies
With a focus on 3Es, Toyota Industries pursues technological innovation to offer the most advanced energy-saving,
electrification and lighter-weight technologies matched to growing needs in the global market for greater environmental
performance. This special feature presents a few examples of our 3E-based technologies in respective fields.

Variable-Displacement Type Compressors

Energy Savings

Toyota Industries’ car air-conditioning compressors boast
the world’s highest-level quality and performance in theareas of compactness, weight reduction, fuel economy,
reliability during high-speed operation and quietness.
Rising global environmental awareness has generated
greater demand for higher energy-saving performance.
In response, we developed the world’s first internallycontrolled variable-displacement type compressor in 1995
and externally controlled variable-displacement typecompressor in 1997, and have continued to pursue
greater performance in these products.
Our externally controlled variable-displacement typecompressors automatically and optimally control the air
conditioner’s cooling capability in accordance with thetemperatures in and outside a vehicle as well as the statusof engine operation. Receiving high acclaim for theiroutstanding performance, they are widely adopted bymajor automakers in and outside Japan.

Lighter Weight

PistonSwash plate
By changing the angle of the swash plate to adjust the piston stroke, the compressor
automatically controls the cooling capability.

Plastic Glazing

Recently, there has been growing demand for reducing
vehicle body weight, which directly leads to improved
fuel economy of an automobile. The weight of glass
accounts for more than 30 kg even in a compact car, andexpectations for plastic glazing have become progressively
greater as a lighter-weight substitute for glass.
Drawing on our experience in developing plastic
glazing, we successfully realized the previously challenging
task of developing a technology to create a larger-sizeplastic glazing. The resulting plastic glazing panoramic roof,
the largest of its kind in the world*1, is used in the Prius α(Prius v in North America and Prius + in Europe) released
by Toyota Motor Corporation in May 2011.
We have been receiving a number of inquiries fromautomakers in and outside Japan. We will further enhance
the appeal of our plastic glazing products to increase thenumber of vehicle models fitted with our products andexpand the scope of applications to include other vehicle
components.

Materials Handling Equipment and Automobile Fields
During the 1990s, we applied accumulated
electrification technologies to the automobile field.
We now develop and produce car electronics productsfor HVs and other electric-powered vehicles.

Since commencing production of electric lift trucks in1967, Toyota Industries has cultivated power electronics
technologies and know-how through the development andin-house production of electronic components fitted in lift
trucks and textile machinery.

Toyota Industries developed a new electric commercial van, “e-Porter,” which contributes to greater logistics
efficiency in a smart mobility society and less CO2 emissions. The e-Porter is a new concept vehicle that combines
energy-saving, electrification and lighter-weight technologies with the keywords of 3Es.

The e-Porter brings together Toyota Industries’ comprehensive technological capabilities including a technology to createa special vehicle that combines its accumulated automotive body design technology with logistics know-how; powerelectronics technology cultivated in developing electric lift trucks and onboard devices for automobiles; and development
strengths in electric drive systems.
For this concept vehicle, we developed a new, dedicatedplatform with a suitable structure for EVs. Specifically, wereduced the number of parts used to successfully achieveboth weight reduction and lower costs. The e-Porter is also
fitted with our newly developed powertrain unit*3 for EVs, an
onboard charger, DC-DC converter and electric compressor,
all of which contribute to reducing environmental impact.
Toyota Industries displayed the e-Porter concept modelat the 42nd Tokyo Motor Show held in December 2011 andpresented the direction we envision for next-generationcommercial vans.
