In September 2026, the first electric ship box-type power supply of Ganfeng Lithium Battery was officially offline. It passed more than 100 certification tests of China Classification Society at one time and obtained the certificate of marine products. This is the first power supply equipped with PACK-level active fire protection in China after CCS "ship application battery power Code 2025" came into effect..

The word "PACK-level active fire fighting" is worth a closer look. The fire fighting scheme of traditional ship batteries is usually to deploy fire extinguishing systems at the cabin level. Once the batteries get out of control of heat, the fire extinguishing agent needs to fill the whole cabin before reaching the heat source, and the response speed is limited. PACK-level active fire protection is to achieve accurate prevention and control at the battery PACK level, and to cooperate with cluster-level heptafluoropropane dual fire protection system to achieve accurate detection, millisecond response, fixed-point suppression, non-diffusion and non-spread of faults.. This scheme is applicable to scenarios such as passenger ship of 300 people, 4000kWh ships carrying dangerous goods and 4000kWh ships sailing in the Three Gorges Reservoir area.

For the PACK factory, ship battery system the threshold is much higher than that of ordinary industrial applications. Electric ship lithium battery needs to meet the high energy density and lightweight design at the same time-the maximum mass energy density of the product exceeds 150Wh/kg, and the maximum volume energy density exceeds 210Wh/L, part of the system adopts all-aluminum Pack shell and all-aluminum bracket scheme to ensure the structural strength and realize lightweight at the same time. The communication architecture must also comply with the IACS UR E26/E27 ship network security standard.Accurate to ensure the data security of intelligent ship operation.

Dongguan Juneng New Energy Technology Co., Ltd. has more than 10 years of engineering experience in battery pack structure design, thermal management application and waterproof technology. The company adopts a multi-layer protection strategy in PACK safety design, locks heat in local areas through aerogel heat proof mat, and releases high-temperature gas with pressure relief channels, the BMS temperature monitoring strategy implements hierarchical response to abnormal temperature rise. This system-level protection design idea is highly consistent with the PACK-level active fire protection concept required by ship batteries. For equipment manufacturers who are entering the supporting field of electric ships, choose a PACK partner who can provide solutions in three dimensions: thermal management, structural protection and BMS strategy, it is becoming the key to whether the project can pass the certification of classification society.
