ELECTRONIC DEVICE FOR CONTROLLING THE ELECTRIC CHARGE OF A LOAD ELECTRICALLY SUPPLIED BY A BATTERY PACK AND SYSTEM FOR MOVING AN ELECTRIC OR HYBRID TRACTION VEHICLE USING THE DEVICE

摘要

An electronic device (28) for controlling the electric charge of a load (L) electrically supplied by a battery pack (21), comprising: a support (29); a control module (30) integrated in the support (29); an electric pre-charging circuit (32) of the load (L), operatively associated to the control module (30), the control module being configured to control the electric pre-charging circuit (32); an electric active discharge circuit (33) of the load (L), operatively associated to the control module (30), the control module (30) being configured to control the electric active discharge circuit (33). The electric pre-charging circuit (32) comprises at least one first solid-state switch and is integrated on the support (29). The electric active discharge circuit (33) comprises at least one second solid-state switch and is integrated on the support (29). The first solid-state switch and the second solid-state switch can be configured to work either as a switch or as a variable resistor.
