Battery Management

Two decades of battery system design — from lead-acid solar to tiny devices running for years on a single AA.

Sh3d has built and managed battery systems for two decades — from lead-acid solar installations down to tiny embedded systems running on a single AA cell for years.

The WII wave buoys sleep for years and run in full-capture mode for months, automatically switching between capture, low-power and sleep modes to maximise longevity, reliability and recoverability.

Battery management is done at a low level: higher-level CPU loads and power drains are progressively shut down so GPS and communications can continue running, allowing a device to be located even when its main systems have failed.
