Problems solved by technology
At present, lithium-ion batteries generally use a test cabinet to conduct centralized charge and discharge tests on a batch of lithium batteries. The test cabinet includes a charging module and a discharging module. The charge and discharge test is carried out at night, and the electricity cost during the day is high, so in order to ensure the progress of production, it is necessary to equip more test cabinets

The invention discloses a charging and discharging circuit, a charging and discharging method and an energy-saving lithium battery charging and discharging system, the charging and discharging circuit comprises a power supply module, a first lithium battery, a second lithium battery and a load; a first charging circuit is arranged between the first lithium battery and the power module, a second charging circuit is arranged between the second lithium battery and the power module, a first electric energy recovery module and a second electric energy recovery module are arranged between the first lithium battery and the second lithium battery, and a first discharging circuit is arranged between the first lithium battery and the load. A second discharging circuit is arranged between the second lithium battery and the load; the electric quantity is recycled through the first electric energy recycling module and the second electric energy recycling module preferentially, after the recycled electric quantity is insufficient, the charging test is completed through the first charging circuit and the second charging circuit, the electric quantity recycling process is also the discharging test process, and high efficiency and energy saving are achieved.
Description
technical field [0001] The invention relates to the technical field of lithium battery testing, in particular to a charge and discharge circuit, a charge and discharge method, and an energy-saving lithium battery charge and discharge system. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. . With the development of science and technology, lithium batteries have become the mainstream. Before lithium batteries leave the factory, it is often necessary to perform charge and discharge tests on lithium batteries. At present, lithium-ion batteries generally use a test cabinet to conduct centralized charge and discharge tests on a batch of lithium batteries. The test cabinet includes a...
