Novel lithium battery module design and device

Abstract

The invention discloses a novel lithium battery module design and device. The device comprises a cell core grid (1), cell cores (2), electrolytic connectors (3), a battery pack (4), a module box (5),a box cover (6), a sealing washer (7), fastening bolts (8), resistance wires (9), a module (10), an air cooling box (11), thermal insulation cotton (12), ventilation tubes (13), battery modules (14),a voltage regulation box (15), and an air conditioning coil (16). A unique double-tank nesting design concept combining liquid cooling and air cooling is adopted by the invention, a liquid cooling medium makes the temperature uniformity of the cell cores better, the cell cores have longer service lives, an air cooling system eliminates the influence of an environmental temperature fluctuation on abattery, the temperature is kept in a reasonable range, the efficient and stable operation of the battery is ensured, the operating temperature range is wide, and the energy consumption of an air conditioning system is significantly reduced.

Description

technical field [0001] The invention relates to a novel lithium battery module design and device, belonging to the technical field of energy storage. Background technique [0002] The global new energy continues to develop at a high speed. With the development of new energy vehicles, renewable energy and distributed power station technologies, the application of energy storage technology in new energy vehicles, renewable energy access and small distributed power stations has become more and more popular. more attention. Advanced energy storage technology can solve the volatility problem of new energy power generation to a large extent. It can not only realize the stable output of new energy power, but also effectively adjust the "changes" of grid voltage, frequency and harmonics caused by new energy power grid connection. , so that large-scale wind power and solar power generation can be safely integrated into the grid. As an energy storage technology, lithium-ion batterie...

AI Technical Summary

Problems solved by technology

The traditional lithium battery energy storage system only adjusts the operating temperature through the air-conditioning cabinet installed in the battery room. This method has poor temperature adjustment accuracy, large energy consumption, and cannot adjust the temperature of the battery core.
