Abstract
A battery module comprising sub-module components, or bricks, that facilitate efficient assembly utilizing common hand tools and provide integrated cooling features for increased battery configurability and performance.
Claims20
A battery brick configured for mating with external components comprising:
- a first battery cell and a second battery cell, wherein the first battery cell and second battery cell are arranged as a first parallel layer of cells;
- a bottom cover and a top cover;
- a first mechanical mating member having at least one cooling medium flow passage and a locating member, wherein the mechanical mating member is configured to restrict the movement of the first battery cell and the second battery cell;
- a first electrical mating member having a parallel layer terminal and a locator aperture,
- wherein the first electrical mating member is configured to provide access to any series elements of the brick and allow parallel connections and voltage sensing of each series element with a single fastener;
- wherein the mechanical mating member and electrical mating member are configured to interface with a second mechanical mating member and second electrical mating member of a second battery brick having at least a third battery cell and a fourth battery cell arranged as a second parallel layer of cells.
3 more elements
A battery module comprising:
- a first battery brick and a second battery brick;
- wherein both the first battery brick and the second battery brick include at least one parallel layer comprising:
- at least one battery cell;
- a mechanical mating member, wherein said mechanical mating member has at least one cooling medium flow passage and a locating member, wherein the mechanical mating member is configured to restrict the movement of the first battery cell;
- a top cover having a flow passage and a bottom cover having a flow passage;
- an electrical mating member having a flow passage and a locator aperture, wherein the first electrical mating member is configured to provide access to any series elements of the brick and allow parallel connections and voltage sensing of each series element with a single fastener.
3 more elements
A battery module comprising:
- a first battery brick and a second battery brick;
- wherein both the first battery brick and the second battery brick comprise:
- at least one battery cell;
