Abstract

The invention discloses a BDU for a new energy automobile. The BDU comprises a shell and the like; a master positive connecting piece, a main positive relay and a high-voltage acquisition interface are connected in sequence; a master negative connecting piece, a main negative relay and a low-voltage control interface are connected in sequence; a pre-charging loop, a discharging loop and a slow-charging loop are arranged in the shell; a heating+pile head, a heating-pile head and a battery+pile head are simultaneously arranged on the front side wall of the shell; a quick charging+pile head, a quick charging- / slow charging-pile head and a slow charging+pile head are arranged on the left side wall of the shell; a discharging+pile head and a discharging-pile head are arranged on the right sidewall of the shell; a battery-pile head is arranged on the rear side wall of the shell; and a quick charging loop and a heating loop are arranged in the shell. The product is added with the quick charging loop, so that the charging time is greatly saved, and the working benefit is improved; the heating loop is added to relieve the influence of cold weather on the battery pack, so that the battery pack gives full play to power; and the design of the protective cover is added, so that safe operation of the electric automobile is guaranteed.

Description

technical field [0001] The invention relates to the field of high-voltage power distribution, in particular to a BDU for new energy vehicles. Background technique [0002] BDU (Battery Pack Disconnect Unit) is a protective battery module in the PDU (Power Distribution Unit) of new energy vehicles. It is an important part of the overall control system of new energy vehicles. Its role is to coordinate the drive motor control system, battery management system, charging management Function conversion and energy distribution of high-voltage accessories such as systems, electric air conditioners, and electric power steering. [0003] At present, the traditional design of the BDU for new energy vehicles only uses the positive and negative output of the control battery and the pre-charging circuit of the main positive relay. The control is simple and there is no fast charging circuit and heating circuit. Contents of the invention [0004] In order to solve the shortcomings of the...
