Abstract:
The present disclosure relates generally to the field of lead-acid batteries. More specifically, the present disclosure relates to handle retention features that are integrated into the packaging of lead-acid batteries. A disclosed lead-acid battery includes a battery handle assembly having a woven fabric strap with a pair of tabs, wherein each tab includes polymer overmolded about a respective end of the strap. The battery also includes a polymer packaging having a cover, wherein a top portion of the cover defines a pair of slots. Each slot is engaged with a respective tab of the battery handle assembly, and wherein each slot includes a respective retention feature that blocks the respective tab from disengaging from the slot.
Abstract:
The present disclosure includes a battery module having a housing with a cell receptacle region defined by walls of the housing and configured to enable passage of electrochemical cells therethrough. The battery module also includes a bus bar carrier sealed in the cell receptacle region. The bus bar carrier includes a perimeter having flexible ribs extending along at least a majority of the perimeter and configured to enable intimate contact between the walls of the housing and the perimeter of the bus bar carrier.
Abstract:
The present disclosure relates to washers for lithium ion battery cell terminals. A lithium ion battery module includes a housing, a first battery cell disposed in the housing and having a cell terminal protruding from a surface of a casing of the first battery cell, where the cell terminal is configured to enable electrical connection to the battery cell, and a washer stack disposed about the cell terminal. The washer stack has an electrically insulative washer and an electrically conductive washer. The electrically conductive washer is disposed adjacent to the electrically insulative washer such that the electrically insulative washer is positioned between the electrically conductive washer and the surface of the casing, and the electrically conductive washer is configured to enable electrical connection to the cell terminal.
Abstract:
The present disclosure relates to a battery module having a housing and a stack of battery cells disposed in a receptacle area of the housing, where each battery cell has a top having a battery cell terminal and a bottom, where the top of the battery cells face outwardly away from the receptacle area. The battery module includes an integrated sensing and bus bar subassembly positioned against the stack of battery cells and has a carrier, a bus bar integrated onto the carrier, and a biasing member integrated onto the carrier. The bus bar electrically couples battery cells in an electrical arrangement, and the biasing member is between the top of each battery cell and the carrier, where the biasing member has a first material, more compliant than a second material of the carrier, and the biasing member biases the stack of battery cells inwardly toward the housing.
Abstract:
The present disclosure relates to a battery module that includes a stack of battery cells disposed in a housing, where each battery cell of the stack of battery cells has a terminal, and a bus bar having a body and an indicator disposed on the body, where the bus bar is configured to couple a first terminal of a first battery cell of the stack of battery cells to a second terminal of a second battery cell of the stack of battery cells. The battery module also includes a sensing component disposed on the indicator and configured to monitor a condition of at least one battery cell of the stack of battery cells and a weld physically and electrically coupling the sensing component to the bus bar.
Abstract:
The present disclosure includes a battery module having a housing with a first end (having a cell receptacle region) and a second end opposite to the first end. The battery module includes a stack of electrochemical cells inserted through the cell receptacle region of the housing, disposed between the first end and the second end of the housing, and having terminal ends of all the electrochemical cells of the stack aligned in a planar area. The battery module includes a bus bar carrier disposed over the stack of electrochemical cells and within the cell receptacle region of the housing. The bus bar carrier includes bus bars disposed thereon that interface with the terminal ends. The battery module includes a layer of thermal epoxy disposed between the second end of the housing and a bottom side of the stack of electrochemical cells.
Abstract:
The present disclosure relates to a battery module having a housing with a first cover and a second cover. The battery module includes a plurality of lithium-ion (Li-ion) electrochemical cells disposed in the housing adjacent to the second cover. The battery module also includes a reinforcement column disposed within the housing that extends along a direction from the second cover to the first cover. The reinforcement column is positioned against the first cover and is coupled to a feature between the first and second covers, and the reinforcement column is configured to enhance a load bearing capacity of the battery module.
