Test instrument you may have not seen - Liuqi Electric Vehicle Capacity Tester

Today, we go to a power-driven battery capacity tester, let's take a look at its internal structure, understand its principle and how to use. First, let's take a look at the main purpose of this product: 1. Applicable to the actual capacity test of various lead-acid, lithium ions, nickel-hydrogen and other battery packs. 2, used to determine the degree of damage to the old battery. 3. Judging the true and false of the new battery. 4. Used in the depth discharge of the battery, remove the battery memory effect, reducing the vulcanization in vivo to repair or maintain a battery. 5, can be used to switch the power supply to the electronic load (constant current mode). Tony said nonsense, look at things, very simple display control panel. Here start to disassemble and get up the screwdriver. This is the internal structure of the capacity tester. A total of six discharge resistors, the same as the spring is the resistance wire. Two heat dissipation fans, the resistance wire will produce a lot of thermal energy, so heat dissipation must be better. This is the surface of the fan shell, with electrical logo, 220V. This is a transformer, we can see that six discharge modules are independently powered mutually uninterrupted, so this tester can make capacity tests for tandem cells. The role of the following modules is that the detection of current detection and voltage and the display function are controlled by the microcontroller. We should see here, it is actually a separate six-way test instrument to be installed in a box. The discharge tube is 75nf75. Circuit city dismantling summary: This product is known as "a variety of styles" to meet the different needs of a variety of people, and multiple choices are selected. But by dismantling us, we know that the Liuyu test is placed in the same box, but this design is still worthy of affirmation, which is convenient for many practitioners. The circuit design is in the middle, the mid-range moments, there is no highlight. Source: Motor DIY, Circuit City Comprehensive Mode Editing
