Abstract

The invention provides a voltage monitor for a 48V rail storage battery. The voltage monitor comprises a first support plate, a second support plate and an upper cover, a DC / DC voltage converter and a battery management system are arranged on the first support plate, the second support plate and the first support plate are vertically and fixedly laminated together, a current sensor, a relay and a heat sink are arranged on the second support plate, a diode is attached and fixed onto a position, facing an inner side surface, of the heat sink, each component is connected according to requirement, the battery management system is used for acquiring current data passing through the current sensor and voltage data of a corresponding storage battery pack and controlling on / off of a switch of the relay, the upper cover is covered on the second support plate in a matching way, and the heat sink is arranged outside the upper cover. The voltage monitor for the 48V rail storage battery is simple and compact in structure and is convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a voltage monitor for a 48V rail accumulator. Background technique [0002] With the development of the new energy business, battery packs are used more and more widely, and nickel-metal hydride battery packs are increasingly used as power supply components on railway passenger cars. However, when the existing Ni-MH battery packs are manufactured, there are no components with data monitoring functions, and abnormalities in battery voltage and current cannot be detected in time, resulting in over-discharging and overcharging of the battery pack, resulting in potential safety hazards and affecting the battery pack. The cycle life is longer, which increases the use cost and maintenance cost to a certain extent. Contents of the invention [0003] The invention aims to provide a voltage monitor for a 48V track storage battery with simple structure, compact structure and convenient assembly and disassembly. [0004] The present i...
