In order to strengthen cooperation with key enterprises in automobile manufacturing, battery production, bus transportation, recycling and other industries, and reduce the pollution brought by new energy vehicle batteries, recently, China Tower Corporation in Beijing and Chongqing Chang'an, BYD, Yinlong New Energy, and Water Sixteen companies including Ma, Guoxuan Hi-Tech and Thornton New Energy signed a partnership agreement on the recycling of power batteries for new energy vehicles.
The “dismantling specification†for new energy vehicle batteries was announced in May 2017 and will be implemented in the near future. According to data from the Ministry of Science and Technology, as of 2017, the number of new energy vehicles in China has exceeded 1 million, accounting for 50% of the global new energy reserves. According to the new energy battery's service life of 5 to 8 years, there are already some new energy vehicles that will face the problem of battery recycling.
At present, new energy vehicles have been arguing over the issue of battery pollution. There is no complete system in China to ease the flow of operations from automakers to battery recyclers. The battery recovery project led by China Towers Corporation will implement standard procedures for manufacturing, recycling, and secondary use in the future, and face the problem of battery pollution.
It is understood that since the beginning of 2015, China Iron Towers has established 57 decommissioned battery ladder test sites in 9 provinces and cities including Heilongjiang and Tianjin, and has conducted active and beneficial explorations on the utilization of waste power battery cascades. The pilot area has been expanded to 12 provinces. The city has built more than 3,000 test sites.

A siren is a loud noise-making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulances, police cars, and fire trucks. There are two general types: pneumatic and electronic.
Many fire sirens (used for calling the volunteer fire fighters) serve double duty as tornado or civil defense sirens, alerting an entire community of impending danger. Most fire
sirens are either mounted on the roof of a fire station or on a pole
next to the fire station. Fire sirens can also be mounted on or near
government buildings, on tall structures such as water towers,
as well as in systems where several sirens are distributed around a
town for better sound coverage. Most fire sirens are single tone and
mechanically driven by electric motors with a rotor attached to the
shaft. Some newer sirens are electronically driven speakers.
Fire sirens are often called "fire whistles", "fire alarms", or
"fire horns". Although there is no standard signaling of fire sirens,
some utilize codes to inform firefighters of the location of the fire.
Civil defense sirens also used as fire sirens often can produce an
alternating "hi-lo" signal (similar to emergency vehicles in many
European countries) as the fire signal, or a slow wail (typically 3x) as
to not confuse the public with the standard civil defense signals of
alert (steady tone) and attack (fast wavering tone). Fire sirens are
often tested once a day at noon and are also called "noon sirens" or
"noon whistles".
The first emergency vehicles relied on a bell. Then in the 70s,
they switched to a duotone airhorn. Then in the 80s, that was overtaken
by an electronic wail.
