CO2 emission regulation

• Automotive has to sell BEVs to meet Strict CO2 emission target

• Regulation allows Eco-Innovation to help OEMs achieve CO2 target (A/C not eligible)



Future LCA regulation

• LCA is the most accurate impact measurement

• It will be difficult to apply it on the whole supply chain6

Production(Cradle to Gate)

Car usage(Well to Tank to

Wheel)

Recycling(Circular economy)



Future LCA regulation (Definition example)

The current regulation includes only the car usage



Future LCA regulation (Daimler vision)

LCA is the most accurate measure but it will difficult to really apply

8



Future LCA regulation (PSA vision)

LCA is the most accurate measure but it will be difficult to really apply

Example of partial evaluation of CO2 rejection by EV and ICE

• EV Global CO2 rejection is lower ICE’s (only manufacturing & usage

• The way to produce the electricity is not included



Economical :

Business model change to services & car sharing => Expectations change (Air Quality, …)

EV over-cost due to the Battery high cost => Pressure to reduce the Thermal system Cost

Globalization of the business => Extension of the requirements to new world needs requirements

11

Impact of Automotive industry Technical :

Engines Hybridization / Electrification

=> Complexity

=> New components

=> Holistic Thermal management

=> Battery thermal management

=> NVH severe requirements

=> Heat-Pump to increase Driving range

Energy consumption reduction

=> Preconditioning to save energy during the driving first minutes

=> Local & personalized comfort to reduce the energy over-consumption

Connected systems

=> Intelligent thermal system

Large screen and nomad devices

=> New airflow concept

DENSO contribution

Engineering :

=> Modular design policy multi-regions

=> From Thermal system management to Holistic Energy management

=> Electronic & Software skills necessity (Mechatronic vs Mechanic, EMC, …)

=> System Thinking

Depending on technology, it is necessary to maintain the battery around

ideal T°to prevent failures and improve reliability

Battery Cycle life temperature

Damage risk

Poor charge /discharge Life-time reduction

Danger



Battery Components Mining

33Battery will be the new precious oil



Electrification impact on NVH requirements

More severe expectation on the previous “hidden

noises” by engine



Heat Pump & EV driving range

35

• Heat Pump is Key Technology for BEV Range Extension

• Modular H/P approach is necessary for multi-energies cars



Local thermal comfort new approach

36

Local comfort target :

Give maximum comfort feeling with low energy

Air-conditioning only the human body

effectively based on body information

37

Example of local comfort : Radiant Heater

Radiant Heater provides immediate effect.

No air-flow, no noise & energy saving



Connectivity provides new precious intern/extern data for car

systems optimization (Thermal & Safety) 38

New intelligent Comfort concept



The future of the central air outlets

• Nomad devices and large screens are pushing air outlets away

• New compatible Dashboard and airflow concept are necessary



40

Example of EV prices (US)

Government incentives compensate “a little” the EV high cost



41Battery cost is an important driver of the EV overcosts

Battery cost evolution



Global RFQ and Modularity design are becoming the standard42

Global requirements



DENSO Technologies supports all new cars trends

• DENSO Thermal supports all automotive trends

• Quicker Cooling/Heating / - Noise Reduction

• Energy efficiency / CO2 reduction / range extension

• Comfort & Safety / Air Quality / Personal AirCon

• Future cabine & Intelligent comfort
