Qué cubre este vídeo

Dan and Kika from Sailing Uma attend Boat Düsseldorf — described as the world's largest indoor boat show — to research replacement batteries for Uma's electric drivetrain, interviewing manufacturers of marine-specific high-voltage and 48-volt systems.0:48 Chris and Jenny from SailHub assist with coverage across 17 halls and 34 battery exhibitors.2:26

EP Technologies (Denmark) presents NMC high-voltage batteries at 5.2 kg/kWh energy density, rated IP65/IP67, with an integral passive fire-suppression system that floods cells with non-dielectric fluid at 68°C before thermal runaway can start.6:06 Their solid-state batteries — demonstrated by driving a nail through a cell with no heat or smoke — carry an ignition threshold above 300°C versus roughly 240°C for LFP and 180°C for standard NMC, and last three to four times longer.8:09 EP Technologies plans 12- and 24-volt solid-state versions for the cruising market by spring.10:33 The interview covers BMS function, per-cell voltage monitoring on prismatic cells, cold-temperature charging limits, deep-discharge recovery down to 2.6V, and Raymarine/Garmin display integration.12:00

GS Power presents a 48-volt, 5.3 kWh stainless-steel marine battery developed for InnoPower, rated fully waterproof, using a MOSFET-based BMS with cell-level voltage monitoring, 125A discharge and 50A charge per unit, parallel-only configuration.22:17
