Problems solved by technology

One of the disadvantages of this technology is the large amount of engineering, and the capacity and voltage cannot be accurately measured during repair; the second disadvantage of this technology is the poor sustainability of repairs. For new batteries, they can be reassembled once after 200 cycles. , the number of reorganizations will be more frequent, so this equalizat

Embodiment Construction

[0102] The present invention is tested with the mechanical shaft transmission mode device.

[0103] 5.5 Mechanical shaft transmission mode device, the bus contact piece is fixed on the inner wall of the housing, and the bus contact piece is composed of two parts: a clockwise equidistant spiral contact piece and a counterclockwise equidistant spiral contact piece; There is a limit device between the clockwise equidistant spiral contact piece and the counterclockwise equidistant spiral contact piece. The rotation of the shaft drives the serial moving contact piece close to the serial bus contact piece until the shaft body or the housing. When the limit device prevents the rotation of the shaft body, the series movable contact piece is in full contact with the bus contact piece, and the battery pack enters the working state. At this time, the series contact piece connects the battery pack in series. When the shaft turns to drive the series moving contact piece to leave the series...

Abstract

The invention relates to an electromechanical device for battery charging and discharging balancing and braking energy recovery. The device is suitable for charging and discharging voltage overall balancing and subsection balancing in the application fields of various secondary batteries and applicable to the motor braking energy recovery, direct-current motor voltage reducing start control and current-double control and circuit connection conversion of an active two-terminal element or a passive two-terminal element. When the device is used for a renewable energy current transforming energy storage system, the battery pack total voltage can be reduced, and the energy storage of voltages of any level is facilitated. The device utilizes two switch driving modes of mechanical shaft driving and electromagnet driving. The two types of electrical work principles are same and used for group conversion of large scale grouped power component connecting circuits. Compared with current semiconductor elements, the device is stable, practical, safe and economical. The device can improve 80% of economic values in the application field.

Description

Technical field: [0001] The invention is an electromechanical integrated device for battery charging and discharging equalization and braking energy recovery. It is suitable for group equalization and segmental equalization of charging and discharging voltage in various secondary battery application fields, for motor braking energy recovery, for low-voltage energy storage of wind and solar energy storage systems, for DC motor step-down start control and multiplication flow control. Suitable for circuit connection conversion of active two-terminal components or passive two-terminal components. Background technique: [0002] 1. The necessity of battery voltage equalization: [0003] There are differences in capacity, internal resistance, assembly, and engineering application environment between secondary battery cells, all of which are concentrated in the voltage at a certain moment. [0004] At present, the 100% DOD cycle of lithium-ion battery cells can exceed 2000 times....
