Survey Background
China poses significant challenges for machinery operation due to its tough and hazardous fields. Moreover, the region experiences a higher battery failure rate compared to other areas. The cross-border delivery of batteries presents logistical difficulties, making it necessary to analyze battery failure components within China and determine the underlying causes of the elevated failure rate.
Surveyed sites
1.Taiyuan

| Machine in Taiyuan |
Taiyuan one of the largest sites and serves as a significant customer base. The majority of machines utilized at this location weigh over 36 tons. The primary tasks performed are digging and dumping. Due to the vast size of the jobsite, finding the ideal machine for the job can be challenging.

| Batter tooth damage |
Some of the tooth and other material in Tool box could touch the battery case. It could make battery leakage.
 |
| Fuse modified |
In Some case, operator sometimes use direct electrical line connected from battery terminal and modified electrical line in fuse box.
Summary
In China, operators often take it upon themselves to modify the electrical circuits, which poses a significant risk of thermal events, especially with lamps and electrical options. Each worksite has its unique characteristics in terms of working modes and conditions. It is crucial for operators to pay close attention to the conditions they are working in. In China, local brand lamps and components are commonly used in the fields due to cost considerations and easier accessibility.
