The Solution
Yamar's devices communicate serially over the existing power bus that connect the Li-Ion cells modules. The high voltage lines transfer the cells state of health, state of charge information to the battery management system (BMS) unit. Saving the need for dedicated wires, simplify the construction of vehicle’s high voltage battery.
The same solution is used in a photo-voltaic system that includes an array of solar panels and a central energy management unit. The Power line communication devices allow optimization of each solar panel to increase the system energy efficiency.
