TOCAD Energy Launches “Battery Testing RS Partners,” a Contract Service for Battery Reliability and Safety Evaluation Tests

Release date: May 14, 2026 TOCAD Energy Co., Ltd. (Head office: Mita, Minato-ku, Tokyo; President and Representative Director: Taro Fujikawa) announced the launch of “Battery Testing RS Partners,” a contract service for reliability and safety evaluation testing of batteries and battery packs. The company will externally offer the secondary battery pack evaluation and development expertise and facilities it has accumulated over approximately 50 years since its founding in 1972, supporting a wide range of customers facing challenges in battery testing and standards certification. Background: Japan’s domestic lithium-ion battery market reached approximately JPY 300 billion in 2024 and is forecast to grow to JPY 1.3 trillion by 2033, at a compound annual growth rate of about 18%. As battery applications expand into EVs, energy storage systems, medical devices, industrial robots, and other fields, demand for compliance with safety standards such as UN38.3, PSE, and IEC62133 is rising sharply. At the same time, reservations for equipment at external testing institutions remain chronically tight, making it difficult for SMEs and startups without their own evaluation resources to secure testing opportunities. TOCAD Energy has decided to respond to these needs by making its in-house equipment, personnel, and expertise available externally, contributing to the development of the industry as a whole. Service overview: Reliability tests cover charge/discharge characteristics, temperature characteristics, cycle characteristics, storage performance, environmental resistance such as low temperature, high temperature, and high humidity, as well as vibration and shock resistance. Safety tests include overcharge, overdischarge, external short circuit, AC charging, thermal shock, heating, drop impact, nail penetration, and crush tests. Standards and certification testing supports UN38.3, PSE, IEC62133, JIS, ISO, UL, and other standards. Related services include proposals for optimal test conditions, support for battery selection and analysis, and battery pack development proposals. Target industries include consumer and industrial equipment manufacturers, cell manufacturers, reuse businesses, research institutions, SMEs, and startups engaged in battery development. TOCAD Energy’s strengths include approximately 50 years of battery pack development and evaluation expertise, as well as various testing environments required for battery testing, including charge/discharge test equipment, constant temperature and humidity chambers with safety specifications, explosion-proof chambers, and nail penetration/crush test machines. The company supports compliance testing based on standards such as UN38.3, PSE, and IEC62133, from single cells to medium and large battery packs exceeding 80V and 250A. Through its integrated system at the Shiroishi Factory in Miyagi Prefecture, covering battery evaluation, design and development, and manufacturing, it also provides issue identification and technical consulting based on test results. Company overview: TOCAD Energy Co., Ltd. was established in January 1972 with capital of JPY 100 million. Its President and Representative Director is Taro Fujikawa. The head office is located on the 16th floor of Sumitomo Fudosan Tokyo Mita South Tower, 3-5-27 Mita, Minato-ku, Tokyo. Domestic bases include the Osaka Sales Office and the Shiroishi Factory in Shiroishi, Miyagi Prefecture; overseas affiliated companies are located in Hong Kong, Zhuhai, and the United States. The company develops, manufactures, and sells secondary battery packs and provides contract battery evaluation testing services.
