Solid State Batteries, a revolutionary development for the marine industry.
A significant step forward
High energy density
Wide temperature range
When we start from scratch, we do extensive failure analyses before and during design stage
Our BMS is robust and proven, used in many industry and marine applications
We measure each single cell voltage and get alarms if one of the cells should get bad instant, even on a trend
4/7 balancing as soon as the cells hit a certain target, this to avoid self-discharge and unneeded heat production
Each cell has its own cell fuse
Gas exhaust system
Pre-charge circuit for start-up
Black-out start, systems can start up when the ship is totally depowered, must have emergency supply battery 24V
PERFORMANCE AND LIFETIME
Like all batteries, also EPTechnologies batteries age, by usage and by calendar aging. Calendar aging is around 1% per year if kept below 30 deg storage temp and if stored at 50 to 60% SOC.
With repeated charging and discharging (cyclical ageing). The 6 year 75% SOC capacity guarantee for the batteries is only valid if below restrictions are followed.
