    Abstract: A control device of a power supply circuit includes processing circuitry. The processing circuitry includes a state-of-charge calculator and a target calculator. The state-of-charge calculator calculate a state of charge of the first battery. The target calculator calculates a target voltage range. When an output voltage of the first battery detected by a voltage sensor cannot be acquired and an acquisition failure occurs, after the occurrence of the acquisition failure, the state-of-charge calculator is configured to obtain the state of charge of the first battery, as a held state-of-charge, that was calculated before the occurrence of the acquisition failure. When a pre-charge process is performed in a state in which the acquisition failure is occurring, the target calculator is configured to calculate an estimated output voltage of the first battery from the held state-of-charge and calculate the target voltage range based on the estimated output voltage.

  • Patent number: 11462929
    Abstract: Electrochemical models for the lithium-ion battery are useful in predicting and controlling its performance. The values of the parameters in these models are vital to their accuracy. However, not all parameters can be measured precisely, especially when destructive methods are prohibited. In some embodiments of the present disclosure, a parameter estimation approach is used to estimate the open circuit potential of the positive electrode (Up) using piecewise linear approximation together with all the other parameters of a single particle model. Up and 10 more parameters may be estimated from a single discharge curve without knowledge of the electrode chemistry using a technique such as a genetic algorithm. Different case studies were presented for estimating Up with different types of parameters of the battery model. The estimated parameters were then validated by comparing simulations at different discharge rates with experimental data.
