In recent days, heavy rains have caused severe floods in various parts of the South. Among them, Hunan Province is the most severely affected. According to preliminary statistics, the number of affected people in Hunan exceeded 4 million, ranking the highest in the same period in history since 1951.

At present, along with the increasing ownership of new energy buses in China, especially new energy buses, there is more urban planning to achieve “no dieselization” of buses. The annual rainy season is also a season for electric buses. In heavy rain, what is the wading performance of pure electric buses? What are the precautions during the rainstorm season? If there is a wading problem, does the pure electric bus have "risk insurance"? In the event of a wading accident, how can an electric bus owner or operator complete the settlement?

Heavy rain weather pure electric bus wading hidden worry

Xia Bangjin, deputy general manager of Hefei Public Transport Group, pointed out in a public occasion that the spontaneous igniting of batteries is a major hidden danger in the safety of new energy vehicles. Because the vehicle's water intake causes the short circuit and leakage of power batteries, it is especially dangerous during the rainy season.

According to media reports, on the morning of July 7, 2016, two electric buses in Nanjing suddenly caught fire. Fortunately, no casualties were caused. According to the results of the later inspections, the battery pack seal standards used by the vehicles caught in the fire are too low, causing the batteries to enter water, causing short circuits and eventually catching fire. In the general public’s cognition, water is a highly conductive substance. If the battery-driven vehicle’s electric vehicle causes spontaneous combustion in the event of a sudden rain and water shortfall, endangering the safety of drivers and passengers, the trust of the electric bus will be greatly reduced. .

"In terms of battery waterproofing, the majority of electric vehicles in China have a waterproof rating of IPX7 or higher, that is, even if the battery is immersed in water, it is not allowed to enter the water under the specified conditions." Yu Zhengjing, Service Manager of Yutong Beijing-Tianjin-Hebei Region, is involved in electric buses. The attitude of water performance is positive. In his opinion, vehicles with a protection level above the IPX7 standard will not have any problems in wading for 30 minutes under normal temperature and pressure.

Insurance is difficult to protect the operation of the rainy season

According to the introduction of the bus home Li Yiren, at present, 30%-50% of domestic electric buses are idle, and this part of the vehicles usually does not have enough insurance. Of the electric buses that were put into operation, only 20% of the vehicles had selected insurance premium insurance + carrier liability insurance + third party liability insurance + vehicle damage insurance, and 30% of vehicles had selected compulsory insurance + third party liability insurance, exceeding 40%. Vehicles are only insured against traffic risks, and less than 10% of the vehicles are not covered by any insurance. In addition, Zhao Chen (a pseudonym), who is responsible for the sales of a new energy bus company, bluntly stated that many passenger transport companies are forced by the pressure of survival and make a fuss about the cost of insurance that occupies a large proportion of the cost. In the repair shop to pay a relatively low amount of 'insurance funds'." Or even choose to "go to the surrounding cities or very small insurance companies insured," This will give the follow-up vehicle after the accident's claims laid a hidden danger.
