  • Patent number: 11539240
    Abstract: A power system within a battery-powered node includes a primary cell, a secondary cell, and a battery controller. The battery controller includes a constant current source that draws power from the primary cell to charge the secondary cell. The battery-powered node draws power from the secondary cell across a wide range of current levels. When the voltage of the secondary cell drops beneath a minimum voltage level, the constant current source charges the secondary cell and a charging signal is sent to the battery-powered node. When the voltage of the second cell exceeds a maximum voltage level, the constant current source stops charging the secondary cell and the charging signal is terminated. The battery-powered node records the amount of time the charging signal is active and then determines a battery depletion level based on that amount of time. Battery replacement may then be efficiently scheduled based on the depletion level.

  • Patent number: 11532946
    Abstract: A power electronics charge coupler (PECC) unit allows vehicle-to-vehicle (V2V) energy transfer by forming a bidirectional buck/boost converter for supplying rapid energy transfer with wide input-output battery voltage and battery voltage levels. The PECC unit embeds DC-DC converter modules into the charging handles of the PECC unit. Each of the charging handles includes a half-bridge of the DC-DC converter and parasitic inductance of a cable between charging handles is utilized as a portion of the filter inductor for the converter. The PECC unit handles are each configured to connect to an electric vehicle and are dynamically configurable in one of four modes of operation based on the battery voltage of the electric vehicles to which the PECC unit is connected and based on which of the electric vehicles is designated as the receiver vehicle and which is designated as the supplier vehicle.

  • Patent number: 11472312
    Abstract: There is provided an electrically driven vehicle used for a car sharing system and configured to appropriately increase the temperature of a power storage device. The electrically driven vehicle used for the car sharing system is provided with a power storage device and a temperature raising device configured to increase temperature of the power storage device. When a user operates a communication device to make a direct reservation or an indirect reservation of the electrically driven vehicle for driving, the electrically driven vehicle estimates a driving start time of the vehicle, based on the position of the communication device, sets a temperature-rising start time of the power storage device, based on the temperature of the power storage device and the estimated driving start time, and controls the temperature raising device to start a temperature increase of the power storage device at the set temperature-rising start time.

  • 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.
