摘要:
A battery controller with monitoring logic for a model-based battery control of a battery performs battery current characterizing, parameter and state variable abnormality detection, and bound checking of error signals between measured and predicted output variables to generate an output. Switching between closed-loop operation (i.e., the model-based battery control) and open-loop operation (i.e., a traditional battery control) is done based on the output of the monitoring logic such that closed-loop stability and performance are reasonably guaranteed.

A method of controlling an electric vehicle including an internal combustion engine, a battery having a state of charge (SOC) and an open circuit voltage (OCV), includes establishing a system for estimating battery SOC. The system includes (i) a parameter estimation subsystem including a recursive parameter estimator for identifying battery parameters and (ii) an OCV estimation subsystem including a nonlinear adaptive observer for estimating battery OCV. Estimated battery OCV is related to estimated battery SOC by a mapping. An output is generated based on the estimated battery SOC.

An electric vehicle includes a controller configured to estimate battery capacity in accordance with a first state of charge estimation, a charge integration, and a second state of charge estimation. The first and second state of charge estimations are in accordance with time and temperature constraints and are such that the estimated battery capacity has limited uncertainty. The controller is further configured to generate an output based on the estimated battery capacity.

A method for determining a power capability for a battery includes the step of defining at least one equation based on a circuit model for the behavior of the battery. The equation includes a plurality of battery parameters, including a battery current. The value of at least one of the battery parameters is measured, and the battery current is solved-for from the at least one equation. A limiting battery current is defined based at least in part on the battery current. A limiting battery voltage is determined, and the power capability of the battery is determined based on the limiting battery current and the limiting battery voltage.

The present invention relates to a method and system for actively publishing a message in an IM group using a chat robot. The method includes: a client adding a chat robot in an IM group satisfying a configured condition; the chat robot automatically obtaining a message and publishing the message in the IM group. In the present invention, a chat robot is added in an IM group, and a function of timed publishing messages by the chat robot is added to increase the message quantity and topics of the IM group, thus not only messages can be sent to users in time, but also IM group activity may be enhanced, which enables users to accept and love the IM group gradually.

An automotive braking system includes a windshield wiper system, a traction wheel, and a non-friction brake system configured to apply a braking force to the traction wheel. The system also includes one or more controllers operatively connected with the windshield wiper system, and configured to, in response to a braking request, command the non-friction brake system to apply the braking force to the traction wheel. The braking force has a magnitude that depends on whether the windshield wiper system is active.
