The present disclosure relates to a redundant power device, and an object of the present disclosure is to provide a redundant power topology that can ensure normal operation of a battery management system (BMS) by securing normal operating power of the BMS even when a disconnection occurs in a cable connecting a battery cell and the BMS or an abnormality or failure occurs in an uppermost battery cell. The present disclosure provides a configuration of switching a power supply cable to a processor so that power is supplied to the processor through a sub-cable when an abnormality occurs in a main cable.

An electric vehicle supply equipment (EVSE) using a Solid-state circuit breaker (SSCB) with an integrated Electric Vehicle (EV) charging interface disposed within a distribution panel allows power to and from an electric vehicle. The EVSE Solid-state circuit breaker further detects arcing on EV load connections or leakage current through ground and disengaging based on an arcing signature or leakage levels through ground. It uses proven materials and technologies that are produced at high volumes, hence taking advantage of economies of scale. Product will be compact in nature and housed in a standard building load center, eliminating the need for an external housing.

An energy storage system (EMS) for mobile and stationary applications includes multiple battery circuits connected in parallel via bidirectional DC-DC converters and managed by centralized or distributed control. Each circuit comprises one or more electrochemical storage elements, and the EMS regulates current flow based on system data indicative of state-of-charge (SOC), state-of-health (SOH), temperature, and chemistry. The EMS performs active balancing by adjusting current commands to equalize SOC across circuits and isolates faulty or degraded modules when necessary. In vehicle applications, the EMS manages power flow between traction batteries, electric drive units, and low-voltage systems, supporting propulsion, regenerative braking, and accessory loads. In stationary systems, the EMS integrates with generators, renewable sources, or grid-tied inverters to coordinate energy delivery, provide backup power, and optimize battery usage.

A closing parameter is calculated that is based on at least one of the comparisons. The closing parameter is compared to a predefined closing parameter value to result in a connect determination. The electronic isolation system connects or disconnects the battery pack to the first set of power contacts based on a positive or a negative result respectively of the connect determination.
