Abstract
The invention relates to a vehicle comprising a motor (M), a converter module (MI), a DC housing module (MDC), and a battery module (MB) comprising an 800V battery (BT). A high-voltage (HV) circuit connects the converter module (MI) to the DC housing module (MDC) and to the battery (BT). A connector (CX) is connected to an 800V negative branch and includes a 400V circuit branch (LV) connected to the motor (M). The converter module (MI) includes an AC / DC converter connected to the motor (M) and the 800V battery (BT). According to the invention, the DC connector module (DCL) includes two capacitance branches (B1, B2), one of which is switchable and connected to a branch (D2) of the 400V branch (LV). The invention also relates to a method and a program based on such a vehicle. Abstract figure: Fig. 2
