摘要： Disclosed are a battery box body and a battery pack. The battery box body includes a lower box body (10) and a cover plate (20). The cover plate (20) is connected to the lower box body (10). One end of the cover plate (20) is bent to form a folded edge (21). A receiving groove (22) for accommodating a low-voltage wire harness (41) is formed between the folded edge (21) and the lower box body (10) to allow the low-voltage wire harness (41) to pass through. In this manner, the folded edge (21) provides position-limiting protection for the low-voltage wire harness (41), thereby serving as a support structure for the low-voltage wire harness (41) to provide protection for the low-voltage wire harness (41), and making it convenient to arrange routing of the low-voltage wire harness (41).
