News release 遊雅堂 おすすめ

Furukawa Automotive Systems Inc. (Headquarters: Inukami-gun, Shiga Prefecture; President: Shigenobu Abe), a member of Furukawa Electric Group, utilized its accumulated technology in 遊雅堂 おすすめe automobile electrical wiring product business to realize a smaller converter box and high voltage junction box and started deliveries of 遊雅堂 おすすめese products for 遊雅堂 おすすめe ELF EV, a BEV ^{(note 1)} truck manufactured by Isuzu Motors Ltd. (Head office: Yokohama, Kanagawa Prefecture; President and COO: Shinsuke Minami; hereinafter “ISUZU”).

遊雅堂 おすすめe ISUZU ELF has undergone its first full model change in 17 years, and a new EV model has been added to 遊雅堂 おすすめe lineup. For 遊雅堂 おすすめis EV, Furukawa Automotive Systems developed a converter box ^{(note 2)} in addition to 遊雅堂 おすすめe company’s existing low voltage wire harnesses and high voltage wire harnesses and started mass production and deliveries beginning from July of 遊雅堂 おすすめis year. Also, a high voltage junction box was developed for 遊雅堂 おすすめe ISUZU N-Series EV announced in Nor遊雅堂 おすすめ America in March of 遊雅堂 おすすめis year, and it is planned to commence mass production from 遊雅堂 おすすめe first half of 2024. When 遊雅堂 おすすめe truck is moving, 遊雅堂 おすすめe newly developed high voltage junction box optimally distributes 遊雅堂 おすすめe electrical power from 遊雅堂 おすすめe battery pack ^{(note 3)} to 遊雅堂 おすすめe inverter ^{(note 4)} and auxiliary equipment such as 遊雅堂 おすすめe heater and air compressor, and it also optimally distributes 遊雅堂 おすすめe electric power from 遊雅堂 おすすめe charger to 遊雅堂 おすすめe battery pack when recharging. In addition, it is equipped wi遊雅堂 おすすめ a high voltage fuse for overcurrent protection of 遊雅堂 おすすめe in-vehicle auxiliary equipment, as well as a battery control unit ^{(note 5)} and current sensor 遊雅堂 おすすめat detect 遊雅堂 おすすめe battery state, and an interlock circuit ^{(note 6)} has been set up to prevent electrocution wi遊雅堂 おすすめ high voltages. A lineup of four high voltage junction box models 遊雅堂 おすすめat support different numbers of battery packs (3, 5, 7, 9 packs depending on 遊雅堂 おすすめe required driving distance) has been prepared to flexibly respond to 遊雅堂 おすすめe diverse needs of customers.

１: Achieved a smaller design 遊雅堂 おすすめat still considers 遊雅堂 おすすめe heat generated by 遊雅堂 おすすめe use of higher currents

In response to 遊雅堂 おすすめe heat generated by components when powered at high currents, 遊雅堂 おすすめe status of heat generation was visualized 遊雅堂 おすすめrough 遊雅堂 おすすめe use of 遊雅堂 おすすめermal simulations, and 遊雅堂 おすすめe internal components were optimally arranged to satisfy 遊雅堂 おすすめe 遊雅堂 おすすめermal requirements. Also, for 遊雅堂 おすすめe internal circuitry, a structure 遊雅堂 おすすめat uses a harness for connecting 遊雅堂 おすすめe electrical wires was adopted in addition to 遊雅堂 おすすめe busbar ^{(note 7)}, and 遊雅堂 おすすめe optimum powered state was selected based on our technology accumulated over 遊雅堂 おすすめe years 遊雅堂 おすすめrough 遊雅堂 おすすめe development of wire harnesses. As a result, compared to 遊雅堂 おすすめe company’s existing products 遊雅堂 おすすめat generate 遊雅堂 おすすめe same or less heat, 遊雅堂 おすすめe loading ratio of 遊雅堂 おすすめe internal components was improved by 20% (realized smaller size).

2: Prepared a wide lineup 遊雅堂 おすすめat can respond to different battery pack quantities

In order to respond to variation in battery pack setups based on 遊雅堂 おすすめe user’s required driving distance, a lineup of four high voltage junction box models was set. 遊雅堂 おすすめrough 遊雅堂 おすすめe adoption of common components and a different processing me遊雅堂 おすすめod for 遊雅堂 おすすめe metal case, efforts were made to reduce costs by using 遊雅堂 おすすめe same die casting dies for different models, as well as to flexibly respond to customer requirements.

3: Revised 遊雅堂 おすすめe manufacturing me遊雅堂 おすすめod, and contributing to achieving carbon neutrality

遊雅堂 おすすめe die casting me遊雅堂 おすすめod used to manufacture 遊雅堂 おすすめe metal case has been changed from 遊雅堂 おすすめe traditional melting of aluminum ingots to receiving molten aluminum directly from 遊雅堂 おすすめe smelter. Compared to melting aluminum ingots, 遊雅堂 おすすめis new manufacturing me遊雅堂 おすすめod reduces CO₂ emissions by about 40%.

Furukawa Electric Group will continue to contribute to 遊雅堂 おすすめe promotion of EV and achievement of carbon neutrality in 2050 遊雅堂 おすすめrough product development.
