Analysis of lithium battery level sanitation sweeper battery self-discharge rate

Source: 2020 - 04 - 01 for hits: the lithium battery health level sweeper battery lithium battery health level frequency sweep the battery self-discharge self-discharge self-discharge is what? The charging ability, self-discharge rate and mean battery when open circuit, battery power under certain conditions. Mainly by the battery production technology, materials, storage conditions and other factors. Is one of the important parameters to measure battery performance. Note: the battery open to 100% charge, the degree of self-discharge is normal. According to the regulations of the national standard of lithium ion in 20 & plusmn; 2 ℃ under open circuit for 28 days. The capacity of the battery can be allowed to be lost. Self-discharge rate and solubility in the electrolyte and anode materials after heating, the instability ( Since the differentiation) The relevant. The rechargeable battery self-discharge is much taller than the self-discharge of the battery at a time. Self-discharge rate and cell types, month is different also. General change between 10% to 35%. Battery was associated with significantly lower self-discharge rate, no more than 2% a year at room temperature. In the process of storage and self-discharge is accompanied by the rise of the battery internal resistance, which would constitute a battery load down, and in the case of large discharge current, the change of the energy loss is very obvious. The following table lists the self-discharge of approximation under normal storage conditions: type/alkaline manganese manganese zinc alloy/round the battery self-discharge: 2% zinc carbon zinc/MnO2 circular battery: & lt; 4% lithium ion MnO2 circular lithium battery: about 1% of lithium ion MnO2 lithium button cell: about 1% of the nickel cadmium battery: & lt; 35% nickel metal hydride battery: & lt; 20-35% lead batteries: 30% click view by phosphoric acid iron battery electric vehicle images domestic high-end lithium battery factory sweeps the floor home is pretty good, now the domestic sales of lithium electric sweepers many are imported, especially the health level of small street sweeper. For example: buch CityCat 2020 ev click to view the picture, talk about buch CityCat 2020 evbuch CityCat 2020 ev is 2 m3 series in the first all-electric small clean car. This machine has set a new standard in reducing noises. Has the function of zero emission and does not affect the power. Payload, suction or cleaning function is not restricted. A special policy is a combination of ecology and economy. CityCat 2020 ev, therefore, has significant low noise, zero emission and better cost effectiveness. Due to reduced fossil fuel, protection, service and maintenance costs, operating costs about 75% lower than conventional diesel-powered cars. A car can reduce 26 tonnes of carbon dioxide a year. Can click to view tai ze 500 small lithium electric sweeper picture 1) Suitable for from school, sidewalks, stores, parks, streets, pick up the paper scraps, such as empty land, soil, gravel, leaves, broken glass, etc. 2) 500 ze USES lithium batteries, no waste, no carbon emissions, adhere to the fresh air and clean city. 3) Cleaning can be dawn, late at night or in parks, schools, hospitals and residential area where noise sensitive receivers. In run mode, pedestrians can hardly hear the movement of the equipment operation. 4) 500 ze, powered by two lithium ion battery, car battery processing system is intelligent monitoring the battery case, balance the power reaches the equipment. Just 4 hours can fully charged battery. In general, the new scheme allows quickly replace the battery if necessary. 5) Efficient lithium battery technology can provide the same as the traditional fuel engine and reliable power supply. 500 ze equipped with real-time power flashlight, alarm, intelligent charging monitoring system with low consumption.
