Abstract: Some embodiments of the present invention provide a system that estimates a state of charge for a battery. During operation, while the battery is relaxing toward a fully rested state, the system determines if a modified state of charge of the battery is substantially consistent with a predetermined decay pattern. If so, the system estimates the state of charge of the battery as a value of the modified state of charge determined at the time when the consistency is observed. Otherwise, the system continues monitoring the modified state of charge of the battery. In one embodiment, the predetermined decay pattern is a single exponential decay. After estimating the state of charge of the battery, the system may determine an uncertainty of the estimated state of charge. More specifically, the system can estimate the uncertainty as substantially equal to a fraction of the difference between the value of the modified state of charge and the value of the voltage-based state of charge at the time when the consistency is observed.

The system also includes a charging circuit configured to charge the plurality of asymmetric battery banks through the series connection. To balance voltages between the battery banks, the system includes a balancing mechanism comprising switching circuitry and an additional switching bank. This balancing mechanism equalizes voltages among the plurality of asymmetric battery banks by using the switching bank to transfer charge among the plurality of asymmetric battery banks during operation of the system, including during charging, discharging, and/or resting.

Abstract: Some embodiments of the present invention provide a system that adaptively charges a battery, wherein the battery is a lithium-ion battery which includes a transport-limiting electrode governed by diffusion, an electrolyte separator and a non-transport-limiting electrode. During operation, the system determines a lithium surface concentration at an interface between the transport-limiting electrode and the electrolyte separator based on a diffusion time for lithium in the transport-limiting electrode. Next, the system calculates a charging current or a charging voltage for the battery based on the determined lithium surface concentration. Finally, the system applies the charging current or the charging voltage to the battery.

Abstract: Configurations for light source modules and methods for mitigating coherent noise are disclosed. The light source modules may include multiple light source sets, each of which may include multiple light sources. The light emitted by the light sources may be different wavelengths or the same wavelength depending on whether the light source module is providing redundancy of light sources, increased power, coherent noise mitigation, and/or detector mitigation. In some examples, the light source may emit light to a coupler or a multiplexer, which may then be transmitted to one or more multiplexers. In some examples, the light source modules provide one light output and in other examples, the light source modules provide two light outputs. The light source modules may provide light with approximately zero loss and the wavelengths of light may be close enough to spectroscopically equivalent respect to a sample and far enough apart to provide coherent noise mitigation.
