Dynamically reconfigurable batteries merge battery management with output
formation in ac and dc batteries, increasing the available charge, power, and
life time. However, the combined ripple generated by the load and the internal
reconfiguration can degrade the battery. This paper introduces that the
frequency range of the ripple matters for degradation and loss. It presents a
novel control method that reduces the low-frequency ripple of dynamically
reconfigurable battery technology to reduce cell ageing and loss. It
furthermore shifts the residual ripple to higher frequencies where the lower
impedance reduces heating and the dielectric capacitance of electrodes and
electrolyte shunt the current around the electrochemical reactions.Comment: 8 pages, 8 figure
