A novel multi-output lithium battery power supply device and its control method

Abstract

The invention relates to a novel multi-output lithium battery power supply device and a control method thereof. The novel multi-output lithium battery power supply device comprises three battery packs arranged on one side of a protection plate support, protection units and control units. The protection units and the control units are arranged on the other side of the protection plate support. The protection units are correspondingly connected with the battery packs respectively. The control units are correspondingly connected with the battery packs respectively. The control method includes the steps that the control units correspondingly detect and judge the charging and discharging states of the first battery pack, the second battery pack and the third battery pack respectively; if the first battery pack, the second battery pack and the third battery pack are in the abnormal charging and discharging states, charging and discharging circuits are correspondingly opened through the combination with the protection units. By means of the novel multi-output lithium battery power supply device and the control method of the novel multi-output lithium battery power supply device, a novel, convenient and stable power supply is provided, and requirements of devices for power supply of various positive and negative power supplies are met.

Description

technical field [0001] The invention relates to a novel multi-output lithium battery power supply device and a control method thereof. Background technique [0002] Traditional multi-power supply equipment often uses more individual power supplies for combined access, which is extremely inconvenient to use. Moreover, equipment powered by multiple power sources has great requirements on the stability of the power supply, safety and reliability, and anti-interference ability. Moreover, the assembly of multiple discrete battery packs is complicated and occupies a large space, which is not conducive to the utilization of equipment structural space. And the installation is fixed. The management circuit is scattered, multiple output lines are connected to the device, the anti-interference ability and stability are poor, and there are problems of functional malfunction. Contents of the invention [0003] The object of the present invention is to provide a novel multi-output lit...
