Toshiba Corporation today announced the launch of a new SCiB lithium-ion battery module featuring advanced heat dissipation capabilities designed specifically for EV buses, electric ships, and stationary power applications. The new module, which incorporates an innovative aluminum baseplate, will be available globally from mid-April 2025.
The module addresses growing industry demands for batteries capable of sustained high-power charging and discharging while managing heat-related degradation issues. By doubling heat dissipation performance compared to current modules, the new product extends battery life during intensive operations.
"Adding new products to its module lineup allows Toshiba to respond flexibly to customer demands and application requirements," the company stated in its announcement, emphasizing its commitment to meeting evolving market needs.
The key innovation in the Type4-23 module is its aluminum baseplate, replacing traditional resin materials. Although aluminum conducts electricity and required special design considerations, Toshiba developed a novel structure that achieves the necessary voltage resistance while leveraging aluminum's superior thermal conductivity.
The new module maintains the core advantages of Toshiba's SCiB technology, which utilizes a lithium titanate negative electrode to deliver safe operation, long service life, excellent low-temperature performance, fast charging capability, and high input/output characteristics across a wide effective state of charge.
Technical specifications include a rated capacity of 45 Ah (1,242 Wh), nominal voltage of 27.6 V, and continuous current rating of 160 A with burst capability of 350 A for 30 seconds. The module weighs approximately 16.5 kg and measures 203.8mm × 395mm × 134.2mm (W×D×H).
The new product will be certified under the UL1973 safety standard for stationary applications, including off-grid systems and microgrids. It features integrated cell voltage measurement, temperature monitoring, cell balancing functions, and communication capabilities.
Toshiba's SCiB batteries are already widely deployed in hybrid vehicles and industrial applications including public transportation, construction equipment, rail systems, and logistics automation. The company indicates it will continue expanding its product line to address customer lifecycle considerations from installation through maintenance and disposal.
