The invention relates to a battery
management system performance
test platform and a testing method based on semi-physical
simulation and belongs to the field of systems. According to the battery
management system performance
test platform and the testing method based on semi-physical
simulation, the problems existing in the aspects of effectiveness, practicality, accuracy, generality and comprehensiveness of an existing battery
management system testing device and method are solved. A BMS to be tested and a
simulation control and emulating unit of the
test platform are connected with a
CAN bus. A
signal output end of an
insulation resistance testing device, a
signal output end of an insulation
voltage resistant testing device, a
signal output end of a 24-channel single-body
voltage simulator, a signal output end of a high-
voltage source, a signal output end of a
current source and current reversing module, a signal output end of a high-accuracy temperature environment box, a signal output end of an
insulation resistance simulator and a signal output end of a
direct current power source are respectively connected with corresponding signal input ends of the BMS to be tested. The BMS to be tested is arranged in a high-low-temperature operational testing box. The testing method comprises the steps of
safety testing and the comprehensive testing of
state parameter measuring accuracy, SOC estimating accuracy, a battery fault diagnostic function, a
heat management function and environment adapting performance and is used for testing the battery management
system.
