Problems solved by technology

[0003] The power battery of a hybrid electric vehicle is composed of multiple batteries in series. In order to meet the collection requirements of the management system, various wiring harnesses need to be added for connection. The assembly complexity is high and the probability of error is high.
The conventional detection method is to manually detect whether the key electrical parameters are correct, use a multimeter to confirm whether the connection is correct, etc., which consumes a lot of manpower and time, and cannot meet the needs of large-scale industrialization

Embodiment Construction

[0025] The electrical connection relationship between the power battery testing equipment and the power battery assembly is as follows: figure 1 shown. The main controller is connected with the self-test indicator light and the input device through signal lines, and the main controller is connected with the LCD display screen through parallel signal lines. The main controller connects the CAN bus, 12V power supply line and other signal lines with the power battery vehicle connector. Usually, the power battery vehicle connector includes the 12V power supply interface, CAN bus interface and other signal line interfaces. Depending on the manufacturer, the signals contained in other signal lines are also different. The other signal lines mainly refer to some signal lines that can enhance system reliability based on various security perspectives at the beginning of the design. The load resistor is connected to the power battery high-voltage wire harness. Among them, the self-insp...

Abstract

The invention provides an inspection device used for the automatic inspection of a power battery for a hybrid electric vehicle, which comprises a main controller, an automatic inspection indicating lamp, an LCD display, an input device and a load resistor. The functions of parameter acquisition and state judgment are realized via the communication between the main controller and the power battery, the automatic inspection result of the device is reflected by the automatic inspection indicating lamp, threshold parameters are variably set by the LCD display screen and the input device, and the load resistor is used for measuring the dynamic characteristics of the power battery. The device can realize the function of automatically inspecting different types of power batteries, and the inspection result is displayed by the LCD display screen. The invention also provides an inspection method, which comprises important steps inspection system initialization, power supply, important parameter acquisition via communication, high-voltage conduction, disconnection, parameter comparison and the like, and logical order. The method can complete the inspection on the basic state of the whole power battery within 1 minute.

Description

technical field [0001] The invention belongs to the technical field of automobile power battery detection, and in particular relates to a detection device and a detection method for automatic detection of a power battery for a hybrid electric vehicle. Background technique [0002] With the development of energy technology and automobile technology, the concept of energy saving and environmental protection is becoming more and more popular.
