1. An electric system comprising:
a first battery module comprising at least one first battery cell, a first battery management system (BMS) and a first BMS switching power supply, the at least one first battery cell and the first BMS switching power supply being disconnected when the first BMS is in an inactive state, the at least one first battery cell and the first BMS switching power supply being connected when the first BMS is in a powered state;
a second battery module electrically connectable to the first battery module, the second battery module comprising at least one second battery cell, a second BMS and a second BMS switching power supply, the at least one second battery cell and the second BMS switching power supply being disconnected when the second BMS is in an inactive state, the at least one second battery cell and the second BMS switching power supply being connected when the second BMS is in a powered state; and
a user-controlled switch adapted for causing a connection of the at least one first battery cell to the first BMS switching power supply for energizing the first BMS and for changing the first BMS from the inactive state to the powered state;
the first BMS being adapted for causing a connection of the at least one second battery cell to the second BMS switching power supply for energizing the second BMS and for changing the second BMS from the inactive state to the powered state when the first BMS is in the powered state;
the first BMS being further adapted for closing a current-limiting path placed in series between the first and second battery modules to start a precharge phase of the electric system once a communication between the first BMS and the second BMS is established.
