We design and manufacture smart DC charge control systems for the marine, RV and commercial transportation industries. Our WS500 Advanced Alternator Regulator is the first of its kind to determine battery charge state by factoring battery voltage, amps-in and amps-out, and alternator and battery temperature – and it's the first regulator on the market to communicate with engine and battery BMS systems via CAN communication.
Firmware V2.2.0 Release

Wakespeed has released firmware Version 2.2.0 for its advanced WS500 alterrnator regulator. This firmware revision delivers significantly upgraded support for CAN-based BMS systems, and represents a major step forward in the delivery of more robust, easier-to-install system integration.

Included in this update are revisions to the default LiFePO4 charge profile, to better match manufacturers' charging recommendations, and improved recording of error messages to aid in accurate diagnostics. In addition, the default setpoint for alternator temperature regulation has been increased from 90°C to 100°C. This new firmware is packaged in a ZIP file, and is available for download on the Technical Page on this website.
