Vehicle-mounted lithium-ion battery energy storage system for engineering

Abstract

The invention discloses a vehicle-mounted lithium ion battery energy storage system for engineering, which comprises a battery system, a bidirectional inverter, a soft starter, a high-voltage controlbox and a vehicle-mounted 12V power supply. The high-voltage control box has built-in battery management system BMS. The battery system is connected with a high-voltage control box through a bidirectional inverter and a soft starter to form an AC charging or discharging circuit. The battery system is directly connected with the high voltage control box to form a DC charging circuit. The battery management system BMS is connected with the battery system through CAN communication, and is connected with a bidirectional inverter through RS485. The vehicle-mounted 12V power supply is a battery system, a bidirectional inverter and a low-voltage power supply of a high-voltage control box. The invention has no pollution discharge during operation and improves the construction environment. In addition, there are many power supply interfaces and flexible power supply mode, which is not affected by time and place, so it is especially suitable for supporting field construction projects.

Description

technical field [0001] The invention belongs to the technical field of battery energy storage. Specifically, the invention relates to a lithium-ion battery energy storage system, especially a vehicle-mounted lithium-ion battery energy storage system for engineering. Background technique [0002] Because the field project construction is far away from the national public power grid, the difficulty of obtaining electricity is the key problem restricting the construction progress of the project. In order to solve the problem of electricity consumption in construction, vehicle-mounted power supply systems with mobile power supply characteristics are widely used in engineering. Today, commercially available on-board power systems usually use generators as the power source. This kind of on-board power system is simple in structure, easy to use, and cheap, and can effectively solve the problem of power consumption in engineering construction. However, the side effects during the u...
