Sanden to Start Supplying Heat Pump System for SAIC EV
June 21, 2019

ROEWE MARVEL X
In February, 2019, Sanden Automotive Climate Systems Corporation (Representative Director & President:
Tadashi Kondo) (SDAS) started providing its automotive air conditioning heat pump system for SAIC’s*1
electric vehicle, ROEWE MARVEL X and Ei5. SDAS began development of this new heat pump system in July,
2017 intending to make it the market first product*2 in China. It is manufactured at Shilong Plant of
Sanden Huayu Automotive Air-Conditioning (SSB).
As environmental awareness grows worldwide, the environmentally-friendly vehicles, such as electric
vehicle, is becoming more popular. It is, however, difficult to utilize exhaust heat as a heat source for
space heating because electric vehicles have no internal-combustion engine. An electric heater is
supplementarily used for heating, which runs a drive battery down and consequently results in decreasing
cruising distance. This new system is designed to extract thermal energy from the outside so that it is
able to perform heating with less power. SDAS was successful in developing its unique heat pump system in
which the year-round balance of energy consumption efficiency for heating/cooling was achieved. The
remarkable features of this heat pump system for this particular vehicle line are as follows.
【Features of this product】
● Improvement in energy efficiency of air conditioning in the outside temperature range of 5 to 25 degrees
Celsius to prevent cruising distance from being decreased.
● Prevention of reduction in cruising distance in winter season through adoption of the vertical type
outdoor heat exchanger which shows improvement in efficiency and drainage performance over the horizontal
type outdoor heat exchanger.

Comment of Mr. Weiguo Gong, Vice President of Technical Center,
SAIC Motor Passenger Vehicle Co., Ltd.
The ROEWE brand of SAIC pursues an advanced blend of customers’ needs and technologies to achieve high
efficiency and excellent energy conservation performance. SAIC adopts the highly efficient heat pump air
conditioning system developed by SDAS for our MARVEL X, the top runner electric vehicle in China. This
heat pump system enables us to satisfy our customers’ requirement to use air conditioning even at 5
degrees below zero, double the heating efficiency, and improve cruising distance in winter. We are
contributing to expansion of Chinese electric vehicle market from the technological aspect.
Comment of Mr. Tadashi Kondo, Representative Director & President, SDAS
Taking account of Chinese national policy of shift to environmentally-friendly vehicle, Sanden group has
strategically been advancing into the Chinese market. It installed a production line for its electric
driven compressors at SSB in August, 2018, so that the global production system for 1.5 million of annual
volume was established. We are honored that SAIC, as a Chinese representative auto maker, appreciated and
adopted our heat pump system. Taking quality first as our motto, we will continually provide first-class
products in collaboration with SAIC.
