A HYBRID FLOOR SAW COMPRISING AN ELECTRIC POWER TAKE-OFF WITH A COMBINED CHARGING SYSTEM, CCS, INTERFACE

Patentradars sammanfattning

This patent covers a hybrid floor saw (Husqvarna AB) that pairs an internal combustion engine (ICE) with an electric machine (EM) to drive a concrete/asphalt cutting spindle, while an onboard electrical energy storage (ESS, <112 V, ≥5 kWh) supplies the EM. A switchable electrical power take-off (PTO) equipped with a Combined Charging System (CCS) interface allows the control unit—responding to operator commands—to selectively export at least 5 kW (preferably ≥15 kW) of electrical power to external equipment such as EVs or heavy construction tools on the work site. The driveline supports serial and parallel configurations, optional first/second clutches for fully-electric or gen-set modes, and recuperative braking via the EM.
