Equipment Overview
Test purpose: The remote control high-current short-circuit
device is designed based on the requirements of various battery
short-circuit test standards. The short-circuit device must meet
the internal resistance range of <5mΩ, so as to obtain the
maximum short-circuit current required by the test. Design overview: The circuit design of the short-circuit
device must also be able to withstand the impact of large currents,
so we will choose industrial-grade DC electromagnetic contactors,
all-copper terminals and internal copper plate diversion, and the
built-in active ball axial flow fan provides effective heat
dissipation protection, which will make the high-current
short-circuit device is safer, effectively reduces the loss of the
test equipment, and ensures the accuracy of the test data. Features

PLC introduction S7-200CN | Processing speed | 0.2~12.ms | | Memory unit | 2K | | Digital | 248 | | Analog | 35 | | Features | PLC has high operability. It has the characteristics of simple
programming, convenient operation, easy maintenance, etc., and is
generally not prone to operating errors. The operation of PLC
includes the operation of program input and program change. The
input of the program can be directly displayed, and the operation
of changing the program can also directly follow the required
address number or contact number to search or search for the
program, and then make changes. PLCs are available in a variety of
programming languages. Used for ladder diagram and electrical
schematic diagram is closer. The PLC has a self-diagnostic
function, which reduces the requirements for maintenance skills of
maintenance personnel. When the system fails, maintenance personnel
can quickly find the fault location through hardware and software
self-diagnosis. |

in flame retardant and corrosion resistance, and easy to clean | | Bottom of box | Install 4 universal wheels and 4 fixed feet, which is not only easy
to move, but also can be parked and fixed stably | | Exhaust system | Independent control, when the test sample produces smoke, the
equipment can automatically detect and discharge the smoke through
the pipeline | | Automatic explosion-proof pressure relief system | It has an exhaust function, that is, a large amount of exhaust gas
generated in the test is discharged to the outside; it has an
explosion-proof pressure relief function, that is, there is a
magnet adsorption pressure relief door (specification: 300*300mm)
at the rear of the protective box. When the strong airflow impacts,
the pressure relief The door opens automatically, reducing the
impact of the explosion. | | Around the explosion-proof box | Equipped with a pressure relief hole, the pressure can be released
in time | | Door of box | It is fixed by high-strength hinges, and at least 3 sets of
explosion-proof locks can be installed on the door to be fixed. | | Principle of explosion-proof box | The double-layer explosion-proof pressure relief structure is
adopted, and the pressure relief holes of the inner layer and the
outer layer are dislocated and separated, which plays a buffering
effect and avoids the ejection of explosive fragments, which plays
a role in safety protection. | | Fire extinguishing device | The explosion-proof box is equipped with a fire extinguishing
device. Once the battery explodes, the fire can be extinguished by
remote control, and the fire extinguishing device and system can be
opened by remote control. | | Lighting system | Open a 400X400 glass hole at the top of the test area, 20MM thick
tempered glass, and install a group of high-brightness LED lights
above the glass to illuminate the entire test space. | | Explosion-proof door design | The front door of the test box adopts a reinforced design, which
can effectively isolate the damage caused by fire and explosion
during the test. The door panel adopts a double-layer design with a
mezzanine, and the hinge and door lock adopt reinforced
equipment-specific standard parts. The window on the door adopts a
double-layer explosion-proof design (the inner layer of
anti-projectile mesh). The explosion-proof door is equipped with an
explosion-proof lock, and an explosion-proof chain is installed on
the explosion-proof door for double protection. |
