The battery comprises a housing (1) with two main chambers (2,3) having a separating wall (5) in between. Two electrode coils (4) are arranged in each of the main chambers. The two coils form storage units that are located within the main chambers. The ele...

An accumulator battery comprising many storage cells in the same battery casing (1) has dividing sections between the cells to receive a cooling medium and the casing has many inlets (2) lying one above the other on the side of the casing which act as inle...

The invention relates to a battery with electrodes formed of spiral wound concentric metal tapes. The current collectors at top and bottom are disc shaped. At the top the current collector (1) has z-shaped contact lugs (2) which contact the top of the cell...

The device has a metal sleeve contact and connection element (4) whose internal diameter corresponds approximately to the external diameter of the connecting pole (2) and that is pressed into a close fit on the connection pole by a guide (3,8) that engages...

In a Ni/metal hydride secondary element with a positive nickel hydroxide electrode, a negative electrode with a hydrogen storage alloy, and an alkaline electrolyte, the positive electrode provided with a three-dimensional metallic conducting framework cont...

The characteristic of the critical charging voltage as a function of the charging current is determined for different temperatures, and linearized by a function of the form A(I)xT+B(I). The values A and B are stored in a battery management system. In opera...

Nickel/metal hydride secondary element comprises a positive nickel hydroxide electrode, a negative electrode containing a hydrogen storage alloy, and an alkaline electrolyte. The positive electrode provided with a three-dimensional metallic conducting stru...

The device has a housing (1) containing a wound electrode arrangement (2) in which the edges of the electrodes are joined to tapping plates (41,42) by laser welding. A number of laser welding points are arranged on most of the surface of the tapping plate ...
