Check battery ports and contact points
Checking battery ports and contact points is an important step to ensure that the battery can properly connect to the external circuit and effectively conduct current.
Check battery ports and contact points
Battery port and contact point inspection is a key step to ensure a stable and reliable connection between the battery and the device during use. By checking the integrity, size, and cleanliness of ports and contact points, you can effectively prevent battery performance degradation, overheating, and short circuit caused by poor contact. This inspection not only helps to ensure the proper operation of the battery, but also improves the safety of the battery and reduces the risk of failures and accidents caused by contact problems. In addition, good port and contact design and inspection can enhance the long-term stability of the battery and ensure the compatibility of the battery with the battery pack or equipment.
Main aspect
Port integrity check
Check whether the battery ports (such as the positive and negative terminals and terminals of the battery) are intact, cracked, dented, or otherwise structurally damaged. Any damaged port may affect the connection between the battery and the device, causing the battery to fail to work properly or a security risk.
Ensure that ports are free of rust or oxidation, which may increase contact resistance, affect current transmission efficiency, or even cause short circuits.
Terminal size and position
Measure the dimensions of terminals and contact points to ensure they meet design standards and can be properly paired with connectors, charging ports, or battery management systems (BMS).
Ensure that the position and shape of the terminal comply with the specifications to avoid poor contact or damage due to assembly errors.
Check the cleanliness of contact points
Check the cleanliness of battery ports and contact points to ensure that there is no dust, oil, or other foreign matter. Dirt may affect the electrical contact between the battery and the battery management system (BMS) or external devices, resulting in degraded battery performance or electrical failure.
Ensure that the surface of the port is clean and flat through necessary cleaning procedures (e.g. wiping, decontamination, etc.).
Welding and joint quality inspection
Check the welding quality between terminals and battery electrodes. Ensure that the welding points are secure and free from welding or cracking. Virtual welding or poor welding can cause poor contact and increase internal resistance, which in turn affects the efficiency and life of the battery.
Perform the necessary electrical connection tests to ensure that battery current flows smoothly and that contact points do not cause overheating or battery damage.
Durability testing of electrical contact points
Durability testing of electrical contact points is performed to simulate wear during prolonged use to ensure that contact points maintain good electrical contact performance during frequent connections and disconnections.
Test the mechanical strength of the contact point to ensure that it can withstand repeated insertion, vibration and other external forces without loosening or breaking.
