I-PEX株式会社（本社：京都府京都市、代表取締役社長：小西玲仁、以下 I-PEX）は、北九州市が推進する北九州エコタウン事業の環境学習拠点「北九州市エコタウンセンター」（北九州市若松区向洋町10-20）に、電気自動車のリチウムイオンバッテリー（以下 EVバッテリー）をリユース・リパーパスした蓄電池システムシリーズ「RENERATH」の「街路灯用内蔵バッテリーBOX」（以下、「バッテリーBOX」）を納入しました。
The Battery BOX, which uses refurbished EV batteries as storage batteries, will be operated as part of a "double-reuse LED lighting" system in combination with refurbished solar panels.
The delivered Battery BOX will be used in the double-reuse LED lighting system.
Background of the Battery BOX Delivery to Kitakyushu City
I-PEXは2024年より、EVバッテリーをリユース・リパーパスした蓄電池システムシリーズ「RENERATH」を通じて、持続可能で安心・安全な蓄電池によるエネルギー活用とEVバッテリーの活用による資源循環を両立する事業を展開しています。また北九州市は、太陽光パネルのリユース・リサイクルを官民一体で進め、太陽光発電の導入拡大と大量廃棄の課題を同時に解決する全国初のモデル「北九州トライアングルモデル」を構築するなど、再生可能エネルギーの導入や資源循環の課題解決に積極的に取り組んでいます。
This alignment of goals led to the introduction of the Battery BOX at the Kitakyushu Eco-Town Center, an environmental learning hub. As part of the city's environmental and disaster-prevention awareness efforts, the RENERATH Battery BOX was introduced as an update to the power supply unit while retaining the existing streetlights.
This initiative is being implemented as part of the Ministry of the Environment's pioneering decarbonization project, promoted by Kitakyushu City and 17 other collaborating municipalities.
About Kitakyushu City's Double Reuse LED Lighting System
The Battery BOX installed in the double reuse LED lighting system.
Kitakyushu City's double reuse LED lighting is installed as an emergency power supply and streetlight units that incorporate not only the Battery BOX, which utilize reused EV batteries as storage batteries, but also reused solar panels.
The electricity generated by the solar panels is stored in the Battery BOX and used to power the LED lighting at night. In the event of a disaster-related power outage, the Battery BOX can be removed and used as an emergency power source.
Installed at the Kitakyushu Eco-Town Center, an environmental learning hub, the double reuse LED lighting system is expected to have an educational and awareness-raising effect on citizens, as it will serve as teaching material that allows them to learn not only about the benefits of EV battery reuse and repurposing on resource recycling and the environment, but also about disaster resilience and disaster prevention efforts through emergency power sources.
2026 Winter Festival
「ダブルリユースLED照明」は、2月7日に開催された「2026ウィンターフェスティバル」においてお披露目されました。会場では、I-PEXの「バッテリーBOX」およびリユース太陽光パネルを題材として、資源循環（リユース・リパーパス）と再生可能エネルギーの活用、停電時の電源確保といった観点から、市民や来場者に向けた説明が行われました。
About RENERATH's Off-Grid Solar Streetlights
RENERATH Off-Grid Solar Streetlight
The RENERATH Off-Grid Solar Streetlight operates solely on renewable energy from solar panels, without the need for an external power source. In addition to its function as an LED streetlight, it features a built-in Battery BOX that can be removed and used as a portable battery during power outages. It can also be operated as a smart pole equipped with optional functions such as security cameras and various sensors.
- Easy to set up, operates off-grid.
The solar panels generate electricity, which is stored in a portable battery box to power the LED lights, allowing the solar streetlights to operate autonomously on their own. - It is used as a streetlight during normal times and as an emergency power source during power outages.
In the event of a power outage, the built-in Battery BOX can be removed and used as a power source at evacuation centers or other locations. - Utilizing reused electric vehicle batteries to maintain charging capacity over the long term
We use high-quality battery modules made from recycled lithium-ion batteries from electric vehicles. - Equipped with a safe and secure battery control system.
This reused battery features functions to appropriately control overcharging, over-discharging, and over-temperature, as well as a protection function to prevent short circuits inside the battery.
Regarding Future Developments
I-PEXは今後、「北九州市エコタウンセンター」での環境・防災啓発への協力を継続するとともに、北九州市をはじめとする九州各地の自治体や教育施設などを中心に「RENERATH」による事業展開を進めていきます。
Furthermore, with regard to the RENERATH Battery Storage System series, we aim to develop a model that balances decarbonization and resource recycling by promoting the social implementation of reused and repurposed EV batteries, with the goal of creating new value through collaboration with our partners and contributing to smart cities.
