Problems solved by technology

At present, the main capacity-distribution equipment of lithium-ion battery manufacturers use resistance to convert into heat and consume it. This part of energy is not only useless, but also causes the temperature of the ambient space to rise sharply, which increases the investment in cooling equipment and consumes less power. rise with it

Embodiment Construction

[0015] Such as figure 1 As shown, in this embodiment, the present invention includes at least one unit module, and the unit module includes an MCU1, a bidirectional AC / DC control board 2, a bidirectional DC / DC control board 3, and the bidirectional AC / DC control board 2 The bidirectional AC / DC rectifier 4 connected and the bidirectional AC / DC converter 5 connected with the bidirectional DC / DC control board 3, the bidirectional AC / DC control board 2 and the bidirectional DC / DC control board 3 Both are connected with the MCU1, and the bidirectional AC / DC rectifier 4 and the bidirectional AC / DC converter 5 are connected. At present, the design of the same industry is based on the way that one main AC / DC drives multiple DC / DCs to run. The main disadvantage of this is that when the main AC / DC fails, the multiple DC / DCs connected to it cannot work normally, affecting Larger surface. This design is a unit modular design, and each unit module has its own AC / DC and DC / DC conversion f...

Abstract

The invention discloses lithium-ion battery forming and grading equipment, and aims at providing high-frequency isolating two-way single-power lithium-ion battery forming and grading equipment with high efficiency, a low heating value and high production efficiency. The high-frequency isolating two-way single-power lithium-ion battery forming and grading equipment comprises at least one unit module, wherein the unit module comprises an MCU (1), a two-way AC / DC control board (2), a two-way DC / DC control board (3), a two-way AC / DC rectifier (4) and a two-way AC / DC converter (5); the two-way AC / DC rectifier (4) is connected with the two-way AC / DC control board (2); the two-way AC / DC converter (5) is connected with the two-way DC / DC control board (3); the two-way AC / DC control board (2) and the two-way DC / DC control board (3) are connected with the MCU (1); and the two-way AC / DC rectifier (4) is connected with the two-way AC / DC converter (5). The high-frequency isolating two-way single-power lithium-ion battery forming and grading equipment is applied to the technical field of the lithium-ion battery forming and grading equipment.

Description

technical field [0001] The invention relates to a lithium-ion battery formation and capacity device, in particular to a high-frequency isolation bidirectional single-power lithium-ion battery formation and capacity device. Background technique [0002] Formation is to activate the inside of the battery through electric energy, and capacity separation is to perform a full-load charge-discharge cycle process on the activated battery. At present, the main capacity-distribution equipment of lithium-ion battery manufacturers use resistance to convert into heat and consume it. This part of energy is not only useless, but also causes the temperature of the ambient space to rise sharply, which increases the investment in cooling equipment and consumes less power. It rises accordingly. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a high-frequency isolated bidirectional si...
