Case Study
Tailored Maritime Battery Solution for Electric Boat Project in Spain
For our client’s electric boat project in Spain, we delivered a custom electric propulsion and battery solution, including maritime-grade battery packs, BMS, PDU, wiring harnesses, and battery racks.
In compliance with strict maritime redundancy regulations, the battery system required multiple fully independent packs (or battery groups), with complete isolation across mechanical structure, electrical architecture, thermal management, and control units.
Based on these requirements, we proposed an optimized configuration consisting of two independent battery groups, each comprising two clusters, with 10 battery modules per cluster.
The BMS adopts a three-level architecture (slave, master, and supervisory controllers) to effectively minimize cell imbalance and prevent associated risks of overcharging and over-discharging.
