Abstract
A battery management system is provided that controls at least a stack of battery cells. The battery management system may detect stack voltage and current. Characteristics of each battery cell in the stack may be monitored. The battery management system may detect ground fault within the stack of battery cells. Communication breakdown and/or failure in the battery management system may also be detected.
Claims20
A system, comprising:
- at least one battery stack having at least one battery cell;
- at least one interface for the at least one battery stack, which when activated, monitors a status of the at least one battery cell;
- a power interface, which when activated, controls whether a load is connected and whether a load is disconnected;
- the power interface includes at least one detector, which when activated detects data indicative of whether a fault is present;
- the power interface, when activated, takes actions based on the data pertaining to the fault.
2 more elements
A method, comprising:
- connecting at least one cell interface to at least one battery cell, the at least one battery cell being connected in series in a circuit, the circuit delivering electrical current to and from the at least one battery cell, wherein the at least one cell interface monitors status of the at least one battery cell;
- communicatively connecting the at least one cell interface to a controller, wherein the at least one cell interface sends the status of the at least one battery cell to the controller;
- communicatively connecting the controller to a power interface, wherein the power interface measures voltage and current in the circuit and sends the voltage and current to the controller, wherein the power interface detects data indicative of whether a ground fault exists;
- wherein the controller sends to the power interface instructions based on at least one of the status of the at least one battery cell, the voltage and current in the circuit, and the data of the ground fault, wherein the power interface controls connecting and disconnecting the circuit.
1 more element
A system, comprising:
- at least one battery cell that is connected in a circuit, the circuit delivering electrical current to and from the at least one battery cell;
- at least one cell interface that is connected to the at least one battery cell, wherein the at least one cell interface monitors status of the at least one battery cell and sends the status to a controller;
- and
- a power interface that controls connecting and disconnecting of the circuit, wherein, when activated, the power interface measures voltage and current in the circuit and sends the voltage and current to the controller, wherein, when activated, the power interface detects data indicative of whether a ground fault exists;
- the controller being communicatively connected to the at least one cell interface and the power interface, when in operation, the controller determines instructions to send to the power interface based on at least the status of the at least one battery cell, the voltage, and the current in the circuit, and the data indicative of whether the ground fault exists.
