Abstract

The invention relates to a power battery parameter collection system. The power battery parameter collection system comprises parameter collection boards and a main control panel; one parameter collection board is mounted in each single battery in a battery pack; the parameter collection boards are used for collecting battery parameters of the single batteries; one main control panel is mounted inthe battery pack; and all parameter collection boards are in wireless connection with the main control panel. One parameter collection board is mounted in each single battery of the system, and the parameter collection boards are used for collecting battery parameters of the single batteries; one main control panel is mounted in the whole battery pack; all parameter collection boards are in wireless communication with the main control panel; the parameter collection boards transmit the collected battery parameters to the main control panel in a wireless manner, so that error caused by line connection and the potential safety hazards of cable damage and the like can be avoided effectively; and meanwhile, the cable acquisition expenses, wiring expenditure and post period maintenance expenditure can be lowered to the maximum degree, the cost is lowered and the service period of the battery pack is prolonged.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a power battery parameter acquisition system. Background technique [0002] In the prior art, there are mainly two ways to monitor battery parameters such as voltage and temperature of a battery cell: manual measurement and wired automatic measurement. [0003] Manual measurement mostly uses multimeters, thermometers, etc. to measure the parameters of each battery. Since manual measurement is to manually measure the parameters of each battery cell, there are problems such as time-consuming, inability to collect the cell information of the entire battery pack synchronously, and manual readings may be falsely reported. [0004] Although the wired automatic measurement can synchronously collect the single information of the entire battery pack. However, an independent acquisition wire needs to be configured for each battery cell. Taking a 450V battery pack commercial vehi...
