Fault finding – Features
The function of the charging circuit is to:
●Ensure electrical energy is supplied to the vehicle whilst respecting the dynamic performance constraints
of the engine and transmission assembly: the alternator resisting torques and the torque gradients
measured must be managed.
●To control alternator loading and load shedding during engine management authorisation or variation of
the electrical load.
●To ensure the quality of the on board network voltage in terms of the voltage level and variation
(voltage gradient management).
●To optimise the battery charge by applying a voltage to its terminals correlating to its initial charge status
(in sleep mode) and to its internal temperature.
●To inform the engine management about the mechanical power taken from the accessories pulley,
the alternator charge rate and the rotor excitation current value.
●To run fault finding on the charging circuit: “Battery” warning light display.
The function of the starting circuit is to:
●Start the vehicle during a starting request with the ignition key if necessary. New Twingo
