Shenzhen Dianzhonghe New Energy Equipment Co., Ltd.
Dianzhonghe is a Shenzhen maker of electrical test equipment for lithium batteries. Its DC-300V tester inspects finished and semi-finished packs: an operator connects the pack and the instrument runs a set inspection sequence. It suits pack assemblers who need a release test at the end of the line.

A specialist in battery electrical testing
Shenzhen Dianzhonghe New Energy Equipment describes lithium-battery testing as its business and lists development, manufacturing, sales and technical service on its official company page. The registered Chinese name is 深圳市电中和新能源装备有限公司. The company gives Longhua District, Shenzhen, as its contact location.
Its range is narrower than a general battery-equipment catalogue. Dianzhonghe groups its products into comprehensive battery testers, charge/discharge aging equipment, PACK or module end-of-line equipment and protection-board testers. The company introduction also names bidirectional DC supplies and regenerative loads. Each family handles a different electrical job, so pick by the task you need done.
The first choice for a buyer is between inspecting an assembled pack and cycling a battery over time. The DC-300V sits in the comprehensive-test family. If your process needs long aging or a different release-test sequence, discuss the DL-series charge/discharge equipment or the separate EOL listings on their own terms, with their own specifications.
Where pack release testing fits
Dianzhonghe works at the last stage of battery production, after cells are grouped, welded into modules and closed into packs. A release tester checks voltage, insulation, protection functions and communication before a pack ships. Cells still need formation and capacity-grading equipment earlier in the line to qualify them.
That makes Dianzhonghe most relevant to pack assemblers and to repair or second-life operators who need a fixed inspection sequence. When you compare it with larger test-system makers, give every bidder the same pack voltage, current and communication protocol, and read each accuracy figure together with its range. If you also need long-duration aging, ask about the company's charge/discharge aging family.

What these details mean for selection
Dianzhonghe's machine on BatteryEquip is the DC-300V Battery Pack Comprehensive Tester. An operator connects an assembled pack and the tester runs the inspection, so it is built for release checks, with no multi-day cell cycling. The machine page covers the test sequence, the configuration options and the points to confirm.
Decide who owns the pack connection
The DC-300V sequence starts once a person has connected the pack. For a production project, ask Dianzhonghe to price the test cabinet, current cables, sense leads, connector fixture and any handling mechanism as separate lines. Cover connector wear and how easily contacts can be replaced, because a worn physical contact will spoil results however good the software is.
Agree who supplies the BMS message map and who demonstrates the MES upload. A good acceptance approach follows one identified pack from connection to its saved release record. It should also show how the system marks an incomplete communication or an aborted step so that neither is logged as a pass.
