International Classification:

G01B 7/16
H01M 10/48

Abstract:

Systems and methods are provided for determining a deformation event in a battery pack. The battery pack may comprise a conductive path coupled to a first electrical connector and a second electrical connector. Processing circuitry may be configured to detect a change in an electrical characteristic of the conductive path indicating a transition from a first circuit state of the conductive path to a second circuit state of the conductive path. The processing circuitry may be configured to determine, in response to the detecting, a deformation event in the battery pack.

International Classification:

G01R 31/00
G01R 31/36

Abstract:

A system for detecting a condition of a contactor configured to connect a battery string to a direct-current bus in a vehicle may include a controller configured to open or close the contactor. The system may also include an alternating-current (AC) signal source configured to provide an AC test signal when the controller opens the contactor. The system may further include an AC coupling circuit. The AC coupling circuit may include a primary side of the AC coupling circuit connected to the AC test signal source, and a secondary side connected to the contactor. The system may also include a detection circuit configured to receive an AC return signal corresponding to the AC test signal, and determine a defective condition of the contactor based on the AC return signal.

Inventors:

- Gardena CA, US
Long Huynh - Gardena CA, US

International Classification:

B60L 11/18
H02M 7/44
B60L 11/08

Abstract:

A system is disclosed for connecting a battery string to a direct-current (DC) bus of a vehicle. The system may include a pre-charge circuit coupled between the battery string and the DC bus. The pre-charge circuit may include a first transistor. The system may also include a first contactor connected to the pre-charge circuit in series. The system may further include a controller configured to close the first contactor and switch on the first transistor.

Inventors:

- Gardena CA, US
Long Huynh - Gardena CA, US

International Classification:

B60L 11/18

Abstract:

A method is disclosed for connecting a plurality of battery strings to a direct-current (DC) bus. The method may include sorting the plurality of battery strings in an order based on respective output voltage values of the battery strings. The sorted plurality of battery strings may include, in the order, at least a first battery string and a second battery string. The method may also include connecting the first battery string to a pre-charge circuit. The method may further include pre-charging the DC bus using the first battery string and the pre-charge circuit. The method may further include connecting the first battery string to the DC bus. The method may further include connecting the second battery string to the DC bus.
