A hybrid battery system is provided for extending the shelf-life of rechargeable batteries. The hybrid battery system may contain sets of non-rechargeable and rechargeable batteries respectively. As the rechargeable batteries are discharged (e.g., from self-discharge), the hybrid battery system may utilize the non-rechargeable batteries to maintain the rechargeable batteries at a preferred state of charge. A preferred state of charge may be selected to extend the shelf-life of the rechargeable batteries. Alternatively, a signal may change the preferred state of charge to prepare the rechargeable batteries for use or for other reasons. The hybrid battery system may contain modular components, thereby allowing for easy replacement of defective or otherwise unsuitable non-rechargeable batteries, rechargeable batteries, or supporting electronics.

Methods and system are provided for a discharge system. In one example, an emergency response vehicle, comprising a battery discharge system having a charging connector configured to electrically couple a capacitor of the emergency response vehicle to a battery of an electric vehicle.

A method of estimating a maximum power limit of a battery cell at a specified prediction time using an improved RC equivalent circuit battery model and based on the battery cell's state of charge (SOC), temperature, and state of health (SOH). The method includes determining the battery cell's peak and continuous current limits, predicting a peak voltage after the specified prediction time based on the peak current limit, determining buffer values for the predicted peak voltage and the temperature of various battery components, setting a maximum current limit based on the buffer values, predicting a maximum voltage after the specified prediction time based on the maximum current limit, and determining a maximum power limit based on the predicted maximum voltage and the maximum current limit.

Provided are a used battery unit holder and a used battery unit storage system capable of easily storing and transporting used battery units from various manufactures while suppressing the deterioration of the used battery units during storage. The used battery unit holder is detachably attachable to a storage device for storing multiple used battery units, including: a connection unit for connecting a used battery unit held in the holder through a circuit included in the storage device in such a manner that the used battery unit can be charged and discharged; a battery status recognition unit which recognizes the battery status of the used battery unit; a charge/discharge instruction acquisition unit winch acquires charge/discharge instruction information; and a charge/discharge management unit which discharges from a discharge-target battery unit and charges a charge-target battery unit in a manner to fall within a predetermined SOC range according to the charge/discharge instruction information.

Disclosed herein is a blind system. The system includes an elongate rod for supporting a length of fabric. The system includes a motor that is connected to a spindle that is configured to rotate the rod about the longitudinal axis to extend and retract the blind in use. The motor may be disposed at a first end of the rod and may have a recess formed therein that is configured to receive a projecting portion of the support.

A safety status display system for an electric vehicle high-voltage (HV) battery is presented. The system contains a battery management module coupled to the HV battery to acquire status information and configured to disconnect the HV battery in the event of a faulty battery condition or a detected electrical insulation defect. An insulation monitoring module installed between the HV battery and the electric vehicle and configured to detect an electrical insulation defect between the HV battery and the frame portion as well as communicate the detected electrical insulation defect to the battery management module. An e-paper display unit coupled to the battery management module to receive the HV battery status information and configured to render a bistable display of the HV battery status information a detected faulty battery condition or electrical insulation defect.

A rechargeable energy storage system includes battery cell(s) and a battery management system (BMS) for detecting cell damage prior to the cell(s) entering an irreversible thermal runaway. The BMS includes gas sensor array(s) for detecting gas(es) vented by the cell(s). Each sensor detects a trace amount of one vented gas indicative of cell damage insufficient to trigger an irreversible thermal runaway. The BMS also includes a controller receiving from the sensor array(s) data indicative of the detected gas trace amounts. The controller compares the detected trace amount with a threshold margin relative to an amount indicative of cell damage that triggers irreversible thermal runaway. The controller additionally identifies damaged cell(s) when the detected trace amount is within the threshold margin. The controller further commands a corrective action to mitigate further damage to the damaged cell(s) and reduce a likelihood of the subject cell(s) entering the irreversible thermal runaway.
