    • The invention relates to the technical field of lithium-ion batteries, in particular to a method for estimating the state of charge of a lithium-ion battery. The method includes: charging a lithium-ion battery, recording multiple groups of ampere-hour integral values, and states of charge and voltage values corresponding to the ampere-hour integral values; taking the maximum value in the multiple groups of ampere-hour integral values as the first ampere-hour integral value, the state of charge corresponding to the first ampere-hour integral value as the first state of charge, and the voltage value corresponding to the first ampere-hour integral value as the first voltage value; monitoring the lithium-ion battery in real time, recording a real-time second ampere-hour integral value and a second voltage value, obtaining a second state of charge by an ampere-hour measuring method; and if the second voltage value is consistent with the first voltage value and the second state of charge is inconsistent with the first state of charge, replacing the second state of charge with the first state of charge. The invention increases the reliable evidence for judging the online equalization of the battery pack and most importantly avoids the situation where the state of charge of the battery can be corrected only on condition that the battery pack works at the extreme state of charge, and lowers the influences of the full charge and discharge on the lifetime of the battery.
    • 本发明涉及锂离子电池的技术领域,特别涉及一种用于估计锂离子电池的充电状态的方法。 该方法包括:对锂离子电池充电,记录多组安培小时积分值,以及对应于安培小时积分值的充电状态和电压值; 将多组安培小时积分值中的最大值作为第一安培小时积分值,对应于作为第一充电状态的第一安培小时积分值的充电状态和对应于 第一安培小时积分值作为第一电压值; 实时监控锂离子电池,记录实时第二安培小时积分值和第二电压值,通过安培小时测量方法获得第二充电状态; 并且如果所述第二电压值与所述第一电压值一致并且所述第二充电状态与所述第一充电状态不一致,则用所述第一充电状态代替所述第二充电状态。 本发明增加了用于判断电池组的在线均衡的可靠证据,最重要的是避免了仅在电池组工作在极端充电状态的情况下可以仅修正电池的充电状态的情况,并且降低 充电和放电对电池寿命的影响。

    • Multi-step statistical modeling in one embodiment of the present disclosure enables anomaly detection, forecasting and/or root cause analysis of the energy consumption for a portfolio of buildings using multi-step statistical modeling. In one aspect, energy consumption data associated with a building, building characteristic data associated with the building, building operation and activities data associated with the building, and weather data are used to generate a variable based degree model. A base load factor, a heating coefficient and a cooling coefficient associated with the building and an error term are determined from the variable based degree model and used to generate a plurality of multivariate regression models. A time series model is generated for the error term to model seasonal factors which reflect monthly dependence on energy use and an auto-regressive integrated moving average model (ARIMA) which reflects temporal dependent patterns of the energy use.

    • A USB (Universal Serial Bus) connector includes an insulating body which has a base portion, an inserting portion, and a pair of clipping walls and defines a receiving space therebetween. A plurality of signal terminals is assembled to the insulating body. Each of the signal terminals has a connecting arm disposed in the inserting portion and a signal contacting arm hanging out of the receiving space. A fixing body is mounted in the receiving space and clipped between the clipping walls. The signal contacting arms are restrained under the fixing body and further stretching behind the fixing body. A ground terminal has a fixing slice fixed in the fixing body, a resilient arm stretching out of the fixing body to be located above the inserting portion and a ground contacting arm restrained under the fixing body and further stretched behind the fixing body to be aligned with the signal contacting arms.
