Battery recycling refers to the collection of used batteries to prevent them from entering the ecosystem and causing harm to the environment. Waste chassis energy storage batteries contain a lot of heavy metals and electrolyte solutions such as waste acid and waste alkali.
Can chassis energy storage battery system be recycled?
What are the disadvantages of chassis energy storage battery system?
How to test the capacity of chassis energy storage battery system?
According to environmental protection experts, for every 1000 grams of metal recovered from waste chassis energy storage batteries, there are 82 grams of mercury and 88 grams of cadmium. It can be said that the recycling and disposal of waste chassis energy storage batteries not only deals with the pollution source, but also realizes the recycling and reuse of resources. We attach great importance to the recycling and utilization of waste chassis energy storage batteries.
95% of the substances in the waste battery can be recycled, especially the recovery value of heavy metals. For example, 55% of the existing lead production comes from recycled lead. In the renewable lead industry, the recycling treatment of waste chassis energy storage batteries accounts for a large proportion. 100kg of waste lead battery can recover 50 to 60kg of lead. For the regeneration treatment of waste batteries containing cadmium, about 20kg of metal cadmium can be recovered by treating 100kg of waste batteries containing cadmium. Environmentally friendly treatment methods are mainly used to prevent from polluting the environment.
The chassis energy storage batteries are usually called maintenance free batteries. In fact, they need to be inspected at least twice a year to ensure that they are free of corrosion, in good working condition and closely connected between single batteries.
In order to ensure the reliability of the chassis energy storage battery, the only way is to monitor the battery. However, each test of the battery will reduce its capacity and shorten its service life.
The service life of sealed chassis energy storage batteries is generally 4 to 5 years. The replacement cost is much higher.
The chassis energy storage battery is heavy in weight and large in volume.
During the battery capacity test, standby power supply must be set as a preventive measure to ensure safety. However, due to the large number of battery packs and long discharge time, the chassis energy storage battery must be charged in time after discharge, which requires a lot of manpower consumption and a certain loss of the battery itself.
The capacity of chassis energy storage battery is the discharge capacity, which refers to the capacity that the outside world can obtain from the battery when the battery discharges under certain conditions. It is generally expressed by ampere hour. Chassis energy storage battery capacity is divided into theoretical capacity, rated capacity and actual capacity according to different conditions.
The commonly used method to test the capacity of chassis energy storage battery is to connect the battery to a load for discharge, according to the constant discharge rate, put it to the termination voltage, stop the discharge, and calculate the product of discharge time and discharge current to obtain the capacity. It is to discharge the core capacity through the discharge instrument.
There are two traditional monitoring methods, that are, manual measurement and wired automatic measurement. Manual measurement cannot be continuous and synchronous in time that there are many human errors and low accuracy. Although wired automatic measurement improves the speed and accuracy of data acquisition and reduces the workload compared with manual measurement, it has more connections and complex operation, which is easy to cause connection errors.
