Southwest Electronic Energy (SWE), an industry leader in subsea batteries has announced that it successfully completed 10,000 psi pressure testing of its SWE SeaSafe Smart Battery Module.
The exhaustive test conducted in the 30 inch hyperbaric chamber at a third party test laboratory included nine complete pressure cycles between zero psi and 10,000 psi while continuously performing battery charge and discharge.
10,000 psi enables a safe operating sea depth of 6,000 meters plus margin. SeaSafe Modules are autonomous battery building blocks each with their own BMS (battery management system).
“In addition to pressure and temperature instrumentation provided by the test lab, the module’s BMS supports continuous monitoring of around 50 module parameters and status registers,” said David White, Senior Member, Technical Staff at SWE.
“And as far as I know, we are the first to support full battery recharge at these depths.”
The pressure test was preceded by a sophisticated external shorts test validating the module automatically shuts off safely for currents in excess of 90 amps.
