 @brief
 This file contains the core code which runs on the BMU LPC1768 MBED. The primary function of the BMU is to obtain the relevant parameters of the battery pack which we are interested in monitoring and]

+placing it on the CAN Bus for the other nodes on the network to utilise. In the event that one of our parameters goes out of a predefined safe threshold (typically specified in the cell manufacturers
 datasheet) we begin to limit the performance of the car so that it gets back to a region needed for safe operation (to be discussed further with telemetry).
