HKS to exhibit at Automotive Engineering Exposition 2023
Product technologies for a sustainable future, such as replaceable battery packs for EVs and battery
degradation diagnostic equipment, will be presented at the Automotive Engineering Exposition 2023
HKS Co., Ltd. (Headquarters: Fujinomiya, Shizuoka; President: Daisuke Mizuguchi) is pleased toannounce its participation in the Automotive Engineering Exposition 2023 YOKOHAMA and theAutomotive Engineering Exposition 2023 ONLINE STAGE 1. The company will showcase a widerange of products, cutting-edge technologies, and its commitment to electriﬁcation for asustainable future.

The Automotive Engineering Expositi on 2023 YOKOHAMA will take place from May 24( Wednesday) to May 26 (Friday). Once again, HKS will present the latest technologies andproducts during the event. Additionally, from May 17 ( Wednesday) to June 7 ( Wednesday),visitors will have the opportunity to access information through the Automotive Engineering
Exposition 2023 ONLINE STAGE 1.

Our exhibition will feature IoT devices, EV batteries, turbogenerators, and advanced ICE
technology. Here are the highlights of each oﬀering:

1. IoT Devices: Experience our cutting-edge Internet of Things (IoT ) devices designed toenhance automotive connectivity, safety, and convenience.

2. EV Batteries: Discover our state-of-the-art electric vehicle (EV ) batteries, which deliver
outstanding performance, range, and durability.

3. Turbogenerators: Learn about our advanced turbogenerators, combining eﬃciency andreliability to meet the power demands of modern automotive applications.

4. Advanced ICE Technology : Explore our innovative internal combustion engine (ICE)technology, designed to maximize performance while minimizing emissions.

01 IoT Connected System① EV Battery Residual Performance Diagnostic System (BLDS)- Developed jointly with Toyo Systems Co.,

② 360°Camera Drive Recorder Solution with AI Analysis③ MAMORU, a s afety device for preventing left behind
pick-up buses (interlocked with key removal).

(Key removal-linked system)

02 Replacement battery packs for EV trucks
The battery packs being developed are introduced aspart of the 'Sector Coupling Demonstration Project for
the Development of EVs with Interchangeable Batteries
and the Use of Renewable Energy', commissioned by theMinistry of the Environment

03 Immersion-cooled batteries for EV
The immersion- cooled battery pack, being developed incooperation with XING Mobility, Taiwan, is introduced. The

batt ery cells are directly immersed in a non-conductiveandnon-ﬂammable

refrigerant,

which

enhancesheatabsorption for eﬃcient rapid charging and discharging.
Add itionally, this design mitigates thermal stress on thecells during abnormal conditions, ensuring a safe andhigh-performance EV conversion system.

04 Turbogenerator
Introduction of engine high-eﬃciency equipment
for converting exhaust energy into electrical energy
for regenerative use.

05 Advanced technology development (internal combustion engines)
HKS is developing more eﬃcient internal combustion
engines to help realize a decarbonized society, and thefollowing are some of the advanced internal combustion
engine technologies we are working on.
1. Pre-chamber combustion technology
Pre-chamber

combustion

technology

enables

rapid

combustion and oﬀers various methods to achieve higher

eﬃciency, such as utilizing a high compression ratio, ultra
lean combustion, and high EGR.

2. 3D camshafts (radial valves)

In the case of conventional camshafts used for oscillating

followers, creating cam proﬁles for radial valves has beenchallenging. However, the HKS cam grinding machine(manufactured by EMAG) is capable of 5-axis grinding,allowing the creation of 3D cam proﬁles that cannot be

reproduced by conventional cam grinding machines.
