![]() ![]() ![]() When charging lithium battery, it will naturally expand, but generally not more than 0.1 mm. Symptom 3: Lithium battery expansionĬase 1: Lithium battery expands when charging. The battery should be carefully tested to control product quality. Solution: Manufacturers should pay special attention to welding procedure. When the battery is processed (spot welding, ultrasonic, etc.), the battery is abnormally heated, causing the thermal closure of the diaphragm and sharply increased internal resistance. Solution: It can be solved by charging and discharging activation. Lithium batteries are stored for too long, resulting in excessive capacity loss, internal passivation, and increased internal resistance. Solution: The internal resistance should be tested by the principle of AC (Alternating Current) bridge method. If the detection accuracy is not enough or the contact resistance cannot be eliminated, it will show that the internal resistance is too large. Root cause 1: Detecting equipment differences. Solution: This low voltage has nothing to do with quality issues and can be solved by charging. In the short-term storage (12 hours), the voltage difference is very small, but the voltage difference is large when stored for a long time. Due to contact resistance or detection of charge, the current is inconsistent caused by the uneven charge of the cell. ![]() Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. Root cause 1: High self-discharge, which causes low voltage. If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected. Hope our post help you with what you need. So in here in this post, we share with you some of the most commonly seen root causes to lithium-ion battery accident and their solutions. As widely used as lithium-ion battery, it’s not uncommon that similar incidents happen every now and then. You can choose the alerts and notifications you want to receive.“…lithium battery caught fire, and exploded…” No, not another one! This is what we say or hear someone else say when there’s news about yet another battery accident. The tracker will even send a warning to your phone if your battery is getting low and needs a charge. You can view real-time data as well as historical results (31 days) that graphically displays the dates, voltages and more. The simple interface makes it easy to monitor the battery’s voltage, automatically check its performance during starting, and test your alternator’s charging operation. The app has three main pages: Voltage Test, Cranking Test and Charging Test. The Antigravity Battery Tracker monitors your vehicle battery status through your phone or tablet by using our free Battery Tracker App (iOS or Android, Bluetooth 4.0). Sends alerts to your Phone when within Bluetooth range. Immediate real-time data and history up to 31 days. Monitor Voltage, Starting Performance and the Charging system. Works on all 12V LITHIUM batteries (we also have Lead/Acid version).Įasily monitor your battery status through your phone using our App. Simple to install and track your battery’s health and status. The Antigravity Battery Tracker is a Bluetooth Monitoring system for your vehicle battery. ![]()
