Battery gas production rate testing device

The utility model belongs to the field of lithium battery testing, and particularly relates to a battery gas production rate testing device which comprises a container body used for containing liquid. The liquid level meter is arranged in the container and is used for measuring the liquid level of liquid; the clamp is used for clamping a battery; the liquid level meter is arranged above the liquid level of the liquid; the clamp is connected with the vertical rod through the cross rod; and the clamp is rigidly connected with the cross rod. The battery gas production rate testing device is high in testing precision, simple, safe and wide in application range, can be applied to measurement of the battery gas production rate after soft package polymer battery pre-charging and electrical performance testing, and solves the problems that a traditional drainage method is large in error, a gas collection method and a pressure method are complex in testing device, low in safety and the like. 本实用新型属于锂电池测试领域，具体涉及一种电池产气量
