Industry Solutions | Battery Accident Handling Methods

1. Industry Background

New energy vehicle battery maintenance is a job that requires high attention to safety. Incorrect operation will not only cause economic losses, but may also cause casualties. Therefore, if a maintenance accident occurs during battery maintenance, there must be appropriate solutions and handling methods.

2. Maintenance accidents caused by common battery failures

1. Battery failure

When a car battery fails, it is mainly manifested as insufficient power to start the engine. This may be caused by battery aging, insufficient charging or over-discharging. If this happens suddenly while driving, it may cause the vehicle to break down and cause traffic hazards. For example, if the battery suddenly fails on the highway, the vehicle loses power and may cause accidents such as rear-end collisions. In addition, during the maintenance process, if the maintenance personnel do not operate properly, such as not using a suitable charger when charging or the charging environment is unsafe, it may cause maintenance accidents such as battery overheating, combustion or even explosion.

2. Battery leakage accident

Battery leakage is the situation where the electrolyte leaks out from the inside of the battery, which will reduce the battery performance and even cause safety accidents such as fire. If the maintenance personnel do not find the leakage during maintenance or do not properly handle the leaked battery, such as not taking protective measures when contacting the leaked electrolyte, it may cause harm to the body. At the same time, if the leaked battery continues to be used or is improperly handled, it may cause more serious accidents such as combustion.

3. Internal short circuit of the battery

Internal short circuit of battery is the abnormal conduction phenomenon between positive and negative electrodes, which will increase the temperature inside the battery and may cause safety accidents such as explosion in serious cases. During the maintenance process, if the maintenance personnel use improper tools, such as causing the positive and negative electrodes of the battery to be accidentally connected, this dangerous situation may occur. Moreover, if the battery after the short circuit is not inspected and repaired according to the correct process, it is easy to cause the accident to happen again.

4. Electric vehicle bottoming accidents

The battery pack of electric vehicles is located at a low position, which is prone to bottoming accidents. Bottom-up accidents can be divided into bottoming scraping and bottoming collisions. Bottom-up accidents are more damaging to the battery pack, which may cause deformation of the battery pack box, damage to the fixing bracket, damage to the connector, damage to the module or single battery, etc. When repairing such bottoming accidents, if the repairman does not accurately judge the degree of damage to the battery pack, he may take the wrong repair method. For example, if the battery pack should be replaced but only a partial repair is performed, it may cause the battery to leak, short-circuit, and other problems in the future, causing a repair accident.

3. Emergency handling methods for maintenance accidents

       1. If skin contact occurs, rinse with plenty of water.

       2. If you inhale gas, you must breathe plenty of fresh air immediately.

       3. If it comes into contact with eyes, rinse with plenty of water (at least 10 minutes).

       4. If the contents of the battery are swallowed, drink plenty of water and avoid vomiting.
