Abstract

The present application relates to a method for estimating the temperature rise rate of a battery under pulsed heating. By establishing an equivalent circuit model of the battery, parameters in the equivalent circuit model of the battery are identified to obtain the effective entropy potential of the battery and the relationship between the open circuit voltage and the pulsed heating current of the battery. The amplitude and period of the pulsed heating current are pulsed parameters. Then according to the effective entropy potential and the relationship between the open circuit voltage and the pulsed heating current of the battery, a heat generation model is established. By using the heat generation model and the heat transfer power of the battery, an energy formulation of the battery in the process of pulsed heating is obtained, so as to obtain the temperature rise rate of the battery under pulsed heating. By establishing an equivalent circuit model of the battery and using the heat generation model of the battery and the heat transfer power model of the battery, the foregoing method can obtain the relationship between the temperature rise rate of the battery under pulsed heating and the pulsed heating current, providing a convenient and comprehensive estimation method for determining the heating effect of pulsed heating in practical applications.

Abstract

The present application relates to a method and system for determining parameters of battery pulsed heating. The reference potential of the anode of the lithium-ion battery is obtained in real time in the positive and negative pulsed heating process under various heating parameters. The reference potential of the anode is the voltage difference between the anode of the lithium-ion battery and the reference electrode. By judging the relationship between the reference potential of the anode and the threshold potential, it is judged whether Li plating has occurred to the lithium-ion battery. Li plating may lead to a decrease in the available capacity of the battery, and puncture of the membrane by dendrite, which causes a short circuit in the battery and induces thermal runaway of the battery, bringing about many hazards such as performance reduction and safety risks. Therefore, when the reference potential of the anode is smaller than the threshold potential, the first heating parameters need to be adjusted to avoid the occurrence of Li plating and improve the life of the battery. By recording the heating parameters when the reference potential of the anode is greater than the threshold potential, it can be ensured that the pulsed heating parameters have no significant impact on the life of the battery.

Abstract

The present application relates to a durability test method and system and a data table generation method for battery pulsed heating. The battery to be tested is put into a temperature chamber, and the temperature of the temperature chamber is set at a first temperature value. The lithium-ion battery is subjected to pulsed heating under first pulse parameters until the pulsed heating time reaches the preset pulse duration. The temperature of the temperature chamber is adjusted to a second temperature value and a capacity degradation value of the battery to be tested is obtained at the second temperature value, so as to obtain durability of the battery to be tested. Before testing of the capacity degradation value of the battery to be tested, continuous pulsed heating is conducted. After the battery is heated for a period of time, the temperature elevation and heat dissipation of the battery will reach stable values and the temperature will no longer rise. Such pulsed heating does not require a long period of standing at low temperature. Therefore, a large amount of test time can be saved, the test period is shortened, and the influence of battery temperature on battery durability can be verified through a large number of experiments.

Abstract

An energetics device is employed to create an outwardly directed pressure wave at a selected depth within a wellbore tubular cemented into a wellbore. The pressure wave causes the wellbore tubular to plastically deform at the selected depth. This locally expands the wellbore tubular at the selected depth, whereby a circumferential recess is created into an inner surface of the wellbore tubular and whereby the outer surface of the wellbore tubular is forced into the surrounding cement sheath at the selected depth. Microcavities and/or micro annuli in the impacted zone may be sealed as a result.

Abstract

The present invention relates to a reactor configuration comprising at least one electrically heated furnace which defines a space, with at least one reactor tube placed within the furnace space and said reactor tube having an exit and entrance outside of the reactor furnace, and wherein said furnace is further provided with - at least one electrical radiative heating element suitable for heating to high temperatures in the range of 400 to 1400 °C, said heating element being located inside said furnace in such a way that the heating element is in no direct contact with the at least one reactor tube; and; and - a number of inspection ports in the furnace wall such to be able to visually inspect the condition of the at least one reactor tube on each opposite side of said reactor tube during operation, the total number of inspection ports being sufficient to inspect all reactor tubes present in the furnace at their full length and circumference; and wherein the heating duty of the furnace is at least 3 MW.

Towards the exit the heat-flux is lower whilst having higher temperature. The present invention can accommodate this requirement. The reactor is useful in many industrial scale high temperature gas conversion and heating technologies.

Abstract

An elastomer sleeve is applied to a wellbore tubular. The elastomer sleeve, which defines a circumference around a longitudinal bore in a longitudinal direction, is brought in an elastically stretched condition by applying a stretching force to the elastomer sleeve. While the elastomer sleeve is kept in the elastically stretched condition, it is moved in the longitudinal direction over the wellbore tubular to a selected position on the wellbore tubular whereby the wellbore tubular extends through the bore. The elastomer sleeve is then snuggly fitted to an outside surface of the wellbore tubular by relaxing the elastically stretching force. The thus prepared wellbore tubular may be lowered into a wellbore in the Earth, and cement may be pumped on the outside of the wellbore tubular to form a cement sheath which fully surrounds the elastomer sleeve.
