Abstract

The invention relates to a heat balance test device and a test method for a fuel cell vehicle. The test device adopts the CAN bus of the vehicle controller, a resolver, a current sensor, a voltage sensor, a temperature sensor, a pressure sensor, a flow sensor, a wind speed sensor and a data acquisition module to synchronously collect data from the vehicle crew compartment, electric stack, cooling water pump, and heat dissipation. Current, voltage, temperature, pressure, flow, wind speed and other key signals of key components such as heaters, heaters, batteries, motors, and controllers. At the same time, it can also collect signals from environmental chambers and chassis dynamometers. The signal collection is comprehensive and reliable. Available Used in high temperature heat balance testing and R&D verification of fuel cell vehicles. The test device uses CAN data, which effectively solves the problem of difficult acquisition of key signals for some thermal management tests of vehicles.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a fuel cell vehicle heat balance testing device and testing method. Background technique [0002] Due to its advantages of energy saving, low carbon and environmental protection, fuel cell vehicles have become a current research hotspot. The high temperature environment adaptability of fuel cell vehicles has become one of the key performances of vehicle development and testing, especially for fuel cell vehicles in high temperature, low temperature, etc. The thermal balance performance in harsh environments has a decisive influence on the performance, safety and life of the vehicle. If the development and design are unreasonable, it will cause damage to the fuel cell components, affect the driving comfort of the vehicle, and even cause safety hazards. Fuel cell vehicle heat balance test components involve a wide range and many demand signals, including fuel cell system, power b...
