1. A method for monitoring a battery, the method comprising:
- transmitting, by a first sensor of a plurality of serially connected sensors configured to monitor the battery, a first data word to at least one further sensor of the plurality of serially connected sensors via a forward channel on a first data line;
receiving, by the at least one further sensor, the first data word, forming by the at least one further sensor a data packet including the first data word and a further data word, and transmitting by the at least one further sensor the data packet to a control unit separate from the plurality of serially connected sensors; and
receiving, by the first sensor from the control unit, the data packet including the first and further data words via a reverse channel on a second data line.

Abstract
A method is described for monitoring a battery, and a battery and a system for carrying out the method in connection with such a battery. A number of sensors are assigned to the battery, the sensors being connected serially to one another and to a control unit via a data line; at least one of the sensors putting in each case at least one data word on the data line.

9. A battery, comprising:
-
a plurality of cells; a plurality of sensors, which are serially connected to one another and to a control unit separate from the plurality of sensors via a forward data channel over a first data line, including a first sensor to transmit a first data word to at least one further sensor via the forward channel, and the at least one further sensor to form a data packet including the first data word and a further data word and transmit the data packet via the forward channel to the control unit; and a reverse channel on a second data line to transmit the data packet including the first and further data words from the control unit to the first sensor. - View Dependent Claims (10, 11)

12. A system for monitoring a battery, comprising:
-
a plurality of sensors, which are serially connected to one another and to a control unit separate from the plurality of sensors via a forward data channel over a first data line, including a first sensor to transmit a first data word to at least one further sensor via the forward channel, and the at least one further sensor to form a data packet including the first data word and a further data word and transmit the data packet via the forward channel to the control unit; and a reverse channel on a second data line to transmit the data packet including the first and further data words from the control unit to the first sensor.
