    摘要： The present invention provides impulse-response-based algorithms for high-speed characterization of electrochemical systems (e.g., batteries) with good accuracy. In some variations, a method for dynamic characterization of an electrochemical system comprises selecting an electrochemical system to be characterized; sensing the measured current to or from said electrochemical system; sensing the measured voltage across said electrochemical system; sensing or calculating the time derivatives of the measured current and voltage; and calculating an impulse response using a recursive or matrix-based algorithm (as disclosed herein), wherein said impulse response characterizes said electrochemical system within a selected sampling window. The algorithms are robust, incorporating noise-reduction techniques, and are suitable for real applications under various operating conditions. These algorithms, and the apparatus and systems to implement them, are able to accept various exciting signals to provide dynamic characterization of various states of the electrochemical system.

    摘要： A handle has opposed ends and a central extent. A grip rotationally receives the central extent of the handle. An adjustment wheel is secured to each end of the handle. A side cover is fixedly secured to each end of the grip. A dowel disk is on the handle adjacent to one side cover with fingers and spaces. A plurality of cam bits are supported on the handle. A safety lock is within the side cover adjacent to the dowel disk. The safety lock has a first end extent and a second end extent with a radial recess and a central extent with an axial projection. A coil spring within the radial recess urges the safety lock radially outwardly. A safety indicator may be seen on one side cover that changes from red to green as the weight selection wheel is turned, indication proper weight selection when green and a potential unsafe condition when red.

    摘要： This invention employs a diamine electrolyte additive that enhances performance of lithium-ion batteries both at high and low temperatures, thereby minimizing the conventional performance gap across a wide temperature range, such as −30° C. to 60° C. At low temperatures, diamine additives can enhances cycling kinetics. At high temperatures, diamine additives can minimize capacity fading. In some variations, a lithium-ion battery electrolyte composition comprises a non-aqueous solvent, a lithium salt soluble in the non-aqueous solvent, and a diamine additive having the formula H2N—R—NH2, wherein R is an organic group such as (—CH2—)n, n=2-12.
