Aerial work platform lithium battery system with constant power function

Abstract

The invention provides an aerial work platform lithium battery system with a constant power function. The aerial work platform lithium battery system comprises an activation switch, a micro-control module, an electronic control module, a constant power control module and a main relay. The two ends of the activation switch are connected to the battery pack and the micro-control module respectively and used for generating an activation signal or a high-voltage cut-off signal. The micro-control module is used for responding to the activation signal, acquiring battery information of the battery pack and managing the battery pack according to the battery information; the main relay is arranged between the electronic control module and the battery pack and is used for correspondingly connecting or disconnecting a loop between the electronic control module and the battery pack in response to the activation signal or the high-voltage cutoff signal; the electronic control module is used for controlling each driving part corresponding to the electronic control module to move when a loop between the electronic control module and the battery pack is connected; and the micro-control module is also used for supplying power to the constant electric control module in response to the activation signal or the high-voltage cut-off signal. According to the invention, the constant electric control module can work continuously.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery system for an aerial work platform with a constant power function. Background technique [0002] At present, more than 95% of the power sources in the high-altitude vehicle field are lead-acid batteries. One of the direct characteristics of lead-acid batteries is that they can output directly without the need for a battery management system, ensuring that some electronic devices that require common electricity on the vehicle remain powered, even if the battery There is no safety hazard in over-discharging, and in recent years, the application of lithium-ion batteries in the field of construction machinery and aerial work platforms has been increasing, and the excellent performance of lithium batteries has been well received by users. [0003] However, lithium batteries must be equipped with a battery management system to prevent overcharge, overdischar...
