Abstract
A hybrid drive of a hybrid vehicle has an internal combustion engine (10), at least one electrical machine (11, 12) and an electrical energy storage (13) that can be discharged when the electrical machine is operated as a motor, and can be charged when the electrical machine is operated as a generator. Each electrical machine (11, 12) has a converter (15, 16) coupled to the respective electrical machine (1, 12) by a plug connection (19, 20), and the electrical energy storage (13) has a converter (14) coupled to the converter (15, 16) of the electrical machine (11, 12) by a plug connection (18). The plug connections (18, 19, 20) are connected firs in a high-voltage circuit and second in a protective circuit. The plug connections (18, 19, 20) are automatically disconnected from the high voltage when the protective circuit is interrupted.
