A transceiver comprising: a transmitter configured to transmit a signal comprising differential voltages to at least a first terminal and a second terminal; at least one receiver; a controller configured to provide control signals to the transmitter to cause the transmitter to transmit symbols, wherein each symbol comprises a predefined set of said differential voltages including at least a positive differential voltage and a negative differential voltage; and a signal balance module configured, for one or more symbols, to: determine a first duration of the positive differential voltage of said one or more symbols; determine a second duration of the negative differential voltage of said one or more symbols; based on determination of a difference between the first and second durations, provide for control of the controller or control of the transmitter to reduce the difference between the first and second durations in a further symbol relative to the one or more symbols.
A transceiver comprising:
The transceiver of any preceding claim, wherein said symbols that the controller is configured to cause the transmitter to transmit, by provision of said control signals, comprise:
The transceiver of any preceding claim, wherein the signal balance module is configured to repeatedly perform said determination of the first duration, determination of the second duration and determination said difference for each symbol caused to be transmitted by the controller and the transmitter and wherein said further symbol comprises a next symbol for transmission.
The transceiver of any preceding claim, wherein the transceiver comprises part of a node of a battery management system, wherein said node provides for one or both of:
The transceiver of any preceding claim wherein said modification of the control signals and said control of the transmitter to reduce the difference between the first duration and the second duration comprises a reduction by the determined difference between the first duration and the second duration of said one or more symbols.
A method for a transceiver, wherein the transceiver comprises a transmitter configured to transmit a signal comprising differential voltages to at least a first terminal and a second terminal, the first and second terminals configured to be coupled to a galvanically-isolated bus;
