In addition, insulation treatment is also required on the EV battery assembly.<\/p><p>The insulation treatment of this part of the station not only affects the safety of the battery, but also affects the safety of the operator.<\/p><h3 id=\"Connection-and-installation-of-high-voltage-copper-bars\">Connection and installation of high-voltage copper bars<\/h3><p>The high-voltage copper bar is used to connect the conduction between the modules, the current is large and the use is intensive, and the assembly is complicated.<\/p><p>As the key structure of the battery conduction, the safety of the EV battery assembly is also very important, and the negligence of the car battery assembly is likely to cause a short circuit of the battery.<\/p><h3 id=\"Car-battery-module-installation\">Car battery module installation<\/h3><p>The battery pack is composed of multiple battery modules.

Generally, long bolts are used to pass through the module and fixed to the nuts at the bottom of the box.<\/p><p>There are also battery packs in the form of double-layer modules to save space, and there will be module mounting brackets for fixing the upper module.<\/p><h3 id=\"Top-cover-installation\">Top cover installation<\/h3><p>In order to meet the needs of light weight and high efficiency, battery packs usually use aluminum casings.<\/p><p>Dozens of bolts are used to connect and assemble the upper cover and the lower box of the battery pack aluminum case.<\/p><p>The bolts are numerous and distributed regularly, and the tightening direction is vertical downward.<\/p><p>It is necessary to tighten sequentially during assembly to ensure that the tightening stress of the upper cover is evenly distributed.<\/p><h2 id=\"Major-difficulties-and-solutions-of-EV-battery-assembly\">Major difficulties and solutions of EV battery assembly<\/h2><p>From the key assembly processes of the above five power batteries, we can understand that the most difficult points of EV battery assembly are the problems of overcurrent parts, insulation and tightening sequence.<\/p><h3 id=\"Overcurrent-parts-problem\">Overcurrent parts problem<\/h3><p>There are many parts in the power battery that will pass current during or after assembly, which are called overcurrent parts. These overcurrent points are usually connecting terminals.<\/p><p>If the connecting terminals are not locked, the contact at the terminal connection will be poor, and there will be a large contact resistance, which is equivalent to connecting a resistor in series in the circuit.<\/p><p>Because of this resistance, when current flows, heat will be generated here. When a large current flows, there will be a large voltage drop on the terminal, which will overheat and may burn the terminal.<\/p><p>Solution: Based on this, it is recommended to use sensor-type electric tools to monitor the tightening process curve in real time to ensure that the assembly terminals achieve the correct torque and prevent false fit and false torque from occurring.<\/p><h3 id=\"Insulation-problem\">Insulation problem<\/h3><p>The battery module will be charged and discharged in the production factory, and the installation and replacement of the module are generally performed under the charged condition.<\/p><p>Therefore, the use of hand-held wired tools has the risk of conductive metal conduction, which eventually forms a loop.<\/p><p><img decoding=\"async\" class=\"aligncenter size-full wp-image-108722\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/07\/Major-difficulties-and-solutions-of-EV-battery-assembly.webp\" alt=\"Major difficulties and solutions of EV battery assembly\" width=\"1000\" height=\"500\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/07\/Major-difficulties-and-solutions-of-EV-battery-assembly.webp 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/07\/Major-difficulties-and-solutions-of-EV-battery-assembly-300x150.webp 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/07\/Major-difficulties-and-solutions-of-EV-battery-assembly-768x384.webp 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/07\/Major-difficulties-and-solutions-of-EV-battery-assembly-600x300.webp 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p>The potential difference passes through the bolt to the tightening tool, and then to the controller. The tool held by the person will also be connected in series to the loop.<\/p><p>There is a great risk in this working condition, because the short-term current generated at 400-600V can be fatal.<\/p><p>In the EV battery assembly, there are many assembly positions with a voltage as high as several hundred volts.<\/p><p>When the bolts are assembled in these positions, the insulation treatment is particularly important.<\/p><p>Solution: When using electric assembly tools with <span style=\"text-decoration: underline\"><span style=\"color: #333399;text-decoration: underline\"><a style=\"color: #333399;text-decoration: underline\" href=\"https:\/\/www.takomabattery.com\/instructions-and-faqs-on-lithium-ion-power-tool-batteries-manufacturers\/\" target=\"_blank\" rel=\"noopener\">power tool batteries<\/a><\/span><\/span>, in order to prevent personal injury, eliminate environmental hazards and product liability cases, it is very important to strictly follow the insulation requirements for tool use. In addition, some insulated tools can be used.<\/p><h3 id=\"Residual-torque-problem\">Residual torque problem<\/h3><p>In EV battery assembly, the upper cover station, connector assembly station, etc. are particularly prone to the problem of torque attenuation.<\/p><p>This is mainly due to the installation of elastic materials, seals, etc. at the connection position, so pay special attention to the sequence of bolt tightening during assembly, and use multiple stages of different bolt assembly tightening speeds to alleviate the torque attenuation of the bolts.<\/p><p>When necessary, a digital display torque wrench can also be used to detect the residual torque of the bolts for quality control.<\/p><p>Solution: In EV battery assembly, torque attenuation caused by different reasons needs to be solved in different ways.<\/p><h3 id=\"Tightening-sequence-problem\">Tightening sequence problem<\/h3><p>As mentioned above, it is necessary to ensure uniform stress distribution when tightening and assembling large flat parts such as the upper cover of the battery pack, so there is a tightening sequence requirement.<\/p><p>By controlling the sequence of tightening the bolts, the stress distribution is ensured as evenly as possible, which can also alleviate the occurrence of torque attenuation to a certain extent.<\/p><p>Solution: Usually, the commonly used tightening sequence control in the factory is to use the ergonomic arm to realize the control of the position point through the encoder.<\/p><p>This method is more conventional, but it is not the optimal solution for the bolt positioning of the battery pack cover.<\/p><p>Because the upper cover of the battery pack usually has a relatively large size range, it will be difficult to cover the arrangement with the force arm, and it is also difficult for personnel to operate, and it is easy to have dead spots in coverage.<\/p><h2 id=\"Technology-prospect-of-future-EV-battery-assembly\">Technology prospect of future EV
