Penghui Energy has obtained patent certificates for utility models such as battery modules and sealing plugs for lithium batteries.

On June 7th, Penghui Energy (300438) announced that the company recently received a patent certificate for a utility model issued by the State intellectual property Office. The name of the utility model is battery module, battery module, sealing plug for lithium-ion battery and lithium-ion battery.

Wherein, the battery module, certificate No. 13307762, inventors Yin Huahao, Yang Hua, Wang Xiangrong, patent number ZL202022665171.X, patent application date November 17, 2020, the utility model provides a battery module, relating to the technical field of battery related technology, the battery module includes a battery module body, the battery module main body comprises a plurality of cells with positive and negative electrodes, and the cells are sequentially connected in series. A plurality of the core groups are arranged in groups and form a plurality of electric core groups arranged side by side; a first insulation isolation board is arranged between the two adjacent core groups. A plurality of cells of the battery module main body of the battery module provided by the utility model can be arranged in groups and form a plurality of core groups, thereby doubling the number of cells of the battery module, compared with the existing mold composition group of the same number of cells, the efficiency of the module composition group is greatly improved, the use of parts and components is reduced, and the cost is reduced.

Battery module, certificate no. 13322870, inventors Huang Sen, Li Wen, Zhu Cong, Wen Hailong, Ding Yonghua, Guo Jun, patent number ZL202022614613.8, patent application date November 12, 2020, the utility model provides a battery module, relating to the technical field of new energy, the battery module comprises a main body of the battery module and a sampling circuit board, and a voltage sampling point connected with the sampling circuit board is arranged on each guide bar. And at least one conductive row of each core group is provided with a temperature sensor connected with the sampling circuit board. A sampling circuit board is arranged on the core set of the battery module provided by the utility model, and the sampling circuit board is located between the positive pole and the negative electrode of the core group, which reduces the distance between the sampling circuit board and the voltage sampling point, and also reduces the distance between the temperature sensor and the sampling circuit board; at the same time, because the connection lines between the sampling circuit board and the voltage sampling point do not cross each other, errors during installation are avoided.

Seal plug for lithium-ion battery and lithium-ion battery, certificate no. 13324492, inventors Chen Gao, Zhou Bin, Liu Yuli, patent number ZL202021995688.9, patent application date, 2020-09-11, the utility model provides a sealing plug for lithium-ion battery and a lithium-ion battery, relating to the technical field of lithium-ion battery, the sealing plug for lithium-ion battery comprises a sealing plug body and a negative pole column, The main body of the sealing plug is provided with a negative pole column hole that runs through the main body of the sealing plug, the negative pole column is arranged in the negative pole column hole, one end of the negative pole column is provided with a negative pole column cap, and the negative pole column cap faces the electric core and is used for welding with the current collector. The sealing plug for lithium ion battery provided by the utility model can increase the welding area of the negative pole column and the current collector plate by facing the end of the negative pole cap toward the battery core, reduce the phenomenon of virtual welding and missed welding, and effectively avoid the leakage or open circuit problem caused by the negative pole column being pushed out of the sealing plug due to the excessive air pressure inside the battery shell.

Battery net noted that recently, Penghui Energy said in investor relations activities that the company's square aluminum shell battery production capacity was planned for 5GWH this year, 2GWh was expanded in Henan and Changzhou bases, and 1GWH was expanded in Zhuhai base, among which Changzhou has 1GWh production line entering the mass production stage, and 4GWh production line is expected to be put into production in the second half of the year; the company's cylindrical battery capacity plans to expand the large cylindrical production capacity of 1GWh in Henan Province, which is expected to be put into production in the second half of the year; The company has a soft package battery capacity and has a follow-up production expansion plan in Zhuhai.
