What NExT-e Solutions does
NExT-e Solutions (now NEXTES Inc. since April 1, 2026) is a Tokyo-headquartered battery technology company founded in 2008 that develops proprietary battery management systems (BMS), grid-connected energy storage systems, and IoT cloud-based energy services. The company serves Japanese power utilities, electric mobility manufacturers, and industrial battery operators across Japan, China, Taiwan, and Germany. Its customer base spans all major Japanese regional power companies — TEPCO, Kansai Electric, Kyushu Electric, Shikoku Electric, and Chugoku Electric — as well as Osaka Gas, Toyota Motor Kyushu, and government counterparties including NEDO and the Tokyo Metropolitan Government, with capital partnerships converting many of these counterparties into shareholders.
The company's core technology stack rests on three patented BMS modules — ACB (Active Cell Balance), AMB (Active Module Balance), and IHS (Intelligent Hot Plug Switch) — that together enable active balancing of lithium-ion cells and modules, parallel connection of battery packs at voltages of 700V or higher, and operation with batteries of varying degradation levels without prior sorting or supplementary charging. These modules underpin a portfolio that includes the 13ft Water-Cooled Grid-Connected Battery System (2,315 kWh nominal capacity, IEC 62933-5-2 certified), BaaS (Battery as a Service) rental operations for forklifts and aerial work platforms in China via wholly-owned subsidiary Shanghai EVTD Inc., VPP (Virtual Power Plant) resource aggregation services across Japan's capacity, supply-demand adjustment, and wholesale electricity markets, and a proprietary IoT cloud platform that performs remote monitoring and AI-assisted anomaly detection.
NEXTES generates revenue through a combination of custom-ordered hardware sales (battery solutions and grid storage systems), recurring subscription revenue (BaaS rentals and Energy Cloud monitoring), and managed services (VPP aggregation). Pricing is not publicly disclosed; enterprise projects are quote-based and contracted on multi-year terms. Distribution is direct to enterprise and government customers in Japan, with international development channeled through Japanese trading houses (Toyota Tsusho, Sumitomo) and the Chinese subsidiary. As of May 2024 the company had 86 consolidated employees and ¥100 million in registered capital, with FY2026 marking the transition from demonstration-scale projects to initial commercial deliveries.
