Design method of portable diagnosis power supply

Abstract

The invention discloses a design method of a portable diagnosis power supply. The design method comprises the following steps: confirming the sizes of a battery cell and a shell; processing a plasticshell; assembling the battery cell; connecting the battery cells in series; leading out a power-on wire; and coating a protective sleeve. According to the design method of a portable diagnosis power supply, the four groups of battery cells are connected in series and a diagnosis power supply capable of directly starting an automobile system is formed; the diagnosis power supply can be used for powering on a battery system of a vehicle under the condition that a vehicle-mounted lead-acid storage battery does not exist, so that the diagnosis work of workers is facilitated, the diagnosis time issaved and thus the staff can deal with the fault of the car battery in time; in addition, the vehicle-mounted power source is simple in structure, convenient to manufacture, low in cost, light in weight, convenient to carry and suitable for diagnosing a battery system under the condition that no vehicle-mounted lead-acid storage battery is arranged outdoors, so that the battery problem can be solved in time.

Description

technical field [0001] The invention belongs to the technical field of diagnostic power supplies, and more specifically relates to a design method of a portable diagnostic power supply. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Vehicles with new technologies and new structures, and new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. With the country's strong support for new energy electric vehicles, the development of new energy vehicles has been greatly promoted, and the output of new energy vehicles has also increased rapidly. During the use of new energy vehicles, due to the mileage, drivin...

Problems solved by technology

[0003] Since most of the faulty vehicles are outdoors, it is difficult to find a matching system power supply to power on the battery system when the battery system is being maintained, so that the battery system can be diagnosed through diagnostic instruments. However, the volume of the existing on-board lead-acid batteries increases. Large, heavy, very inconvenient to carry, at the same time, it needs to be diagnosed after the battery system is disassembled and written, and the wiring needs to be reconnected to install the battery system, which consumes working time, so a simple and portable power supply is needed. To be able to power up a battery system without an on-board lead-acid battery, we need to come up with a design approach for a portable diagnostic power supply
