Abstract:
A lithium-ion battery may be provided. The lithium-ion battery may comprise: a housing (4) defining an opening end, a cover assembly (42a, 42b) sealing the opening end, a positive terminal (11) and a negative terminal (21), a battery core (3) positioned within the housing (4), an electrolyte filled within a space formed by the housing (4) and the cover assembly (42a, 42b); and an electrical protection element (9) electrically connected between the negative terminal (21) and one of the cover assembly (42a, 42b) and the housing (4).
Abstract:
A battery system having interconnected battery packs (2300) is provided. Each battery pack (2300) includes a plurality of rectangular prismatic shaped cells (300). Each cell (300) includes a positive terminal at one end and a negative terminal at the other end. The cells (300) are housed in a battery pack housing (2305) in a side-by-side manner. The cells (300) may be electrically connected in series so that the positive terminal for a cell (300) extends toward and contacts the negative terminal of an adjacent cell (300) and the negative terminal for the cell (300) extends toward and contacts the positive terminal of another adjacent cell (300).
Abstract:
The present invention discloses a method and a device for controlling battery heating. The method may comprise the following steps of: starting battery heating when conditions for starting battery heating are met; and stopping battery heating when conditions for stopping battery heating are met. The conditions for stopping battery heating may be at least one of the following: (a) an absorbed energy of the battery reaching a predetermined energy; (b) a period of time during which a discharging current of the battery maintains constant reaching a predetermined period of time; (c) the discharging current starting to decrease; or a heating time reaching a maximum heating time. The method and the device according to the present invention consider a plurality of conditions including temperature, discharging current, battery SOC and heating time etc. to determine battery heating, which may meet requirements of the practical applicabilities and may not damage the battery with enhanced battery lifespan.
