1. A system for wireless communication in an electric vehicle and having a normal operating mode and a noise immunity operating mode, the system comprising:
a first wireless cell node in electrical communication with a first plurality of battery cells, the first wireless cell node including a first transceiver device;
a battery management system controller subsystem including a network manager, wherein the network manager includes a second transceiver device configured to wirelessly communicate with the first transceiver device,
wherein the first transceiver device and the second transceiver device are configured to switch from the normal operating mode to the noise immunity operating mode when a noisy environment is determined to be present,
wherein the normal operating mode has a first lengthening factor with a first number of transmitted bits per bit of information, and wherein the noise immunity operating mode has a second lengthening factor with a second number of transmitted bits per bit of information that is greater than the first number of transmitted bits per bit of information.
