For the race strategy these are important questions to answer if you want to be as efficient as possible. In Nuna8 the energy streams are continuously measured by imc µ-CANSAS modules. These modules accurately convert analog voltages into digital CAN-bus data. The currents are measured by means of the small voltage drops across shunt resistors. imc µ-CANSAS modules are available with one channel and with four channels. The single channel module is so small, it can be built into the battery module of Nuna8.
"The µ-CANSAS modules simply have it all: Small mass, low energy consumption and accurate measurements." according to one of the team members.
