Patent number: 10852332Abstract: Wide deployment of high voltage battery systems in traction, industrial and renewable energy installations is raising the concerns for human safety. Exposure to hazardous high voltages may occur due to deterioration of insulation materials or by accidental events. It is thus important to monitor for such faults and being able to provide timely warnings to affected persons. For this purpose it has become mandatory for electrified passenger vehicles (CFR 571.305) to maintain high isolation values which can be continuously monitored by electrical isolation monitoring devices. The task of monitoring isolation resistance within the electrically noisy car environment is not a trivial task and the solution to this problem has become quickly a field of research and innovation for all affected industries.Type: GrantFiled: January 30, 2019Date of Patent: December 1, 2020Assignee: Sendyne CorporationInventors: Nicolas Clauvelin, Victor Marten, Ioannis Milios

Publication number: 20200081417Abstract: A complete model numerical solver resides on an embedded processor for real time control of a system. The solver eliminates the need for custom embedded code, requiring only model equations, definition of the independent and dependent variables, parameters and input sources information as input to solve the model equations directly. Through elimination of the need for custom code, the solver speeds up the model deployment process and provides the control application sophisticated features such as Automatic Differentiation, sensitivity analysis, sparse linear algebra techniques and adaptive step size in solving the model concurrently.Type: ApplicationFiled: November 10, 2019Publication date: March 12, 2020Inventors: Robert C.

Patent number: 9812877Abstract: Cell balancing aims to prolong the battery operating life by equalizing the Electro Motive Force (or Open Circuit Voltage) of the participating cells. Even perfectly balanced cells though will exhibit different output voltages because of differences in their internal impedances. The difference in voltage will depend on the load current frequency and intensity. A method is described for re-distributing charge in such a way so when the worst (from the point of view of voltage spread) possible load conditions occur, cells will have similar outputs and none will cross the under-voltage threshold causing a premature shut down of the battery.Type: GrantFiled: February 18, 2015Date of Patent: November 7, 2017Assignee: Sendyne CorporationInventor: Ioannis Milios

Publication number: 20170234933Abstract: A method predicts the battery state in “real-time”, which is based on a nodal algorithmic model. Under this method, the battery is modeled as a network mesh of both linear and non-linear electrical branch elements. Those branch elements are interconnected through a set of nodes. Each node can have several branches either originating or ending into it. The branch elements may represent loosely some particular function or region of the battery or they may serve a pure algorithmic function. The non-linear behavior of the elements may be described either algorithmically or through lookup tables. Kirchhoff's laws are applied on each node to describe the relationships between currents and voltages. The system may be connected with a battery so that it can receive measured values at the battery, and the system yields state-of-charge, state-of-health, and state-of-function signals.Type: ApplicationFiled: January 23, 2015Publication date: August 17, 2017Inventor: Ioannis Milios

Publication number: 20140203737Abstract: What is described is a battery management architecture that eliminates previously described problems of the previous solutions and compensates for the extra cost of a cell-balancing circuit. These advantages are achieved by integrating the voltage step-up and balancing functions as well as charging functions inside a single converter topology. Instead of providing the entire output voltage and power, the converter in this configuration is merely assisting the battery by providing a portion of the power delivered to the load, rather than the entirety of the power delivered to the load. This portion of power is proportional to the difference between the output and the battery pack voltages.Type: ApplicationFiled: August 27, 2013Publication date: July 24, 2014Inventors: Aleksandar Prodic, Mahmoud Shousha, Victor Marten, Ioannis Milios

Publication number: 20120256593Abstract: A series array of electrochemical cells is charged by first applying a first charging current to the series array, thereby applying the first charging current to each of the cells in the series array. When one of the cells reaches a predefined maximum voltage, the series charging current is ceased. A second charging current is then selectively applied to various of the cells in the series array, topping up each of the cells in the series array. Priority is given to the weakest cell in the array. If there is an idle time for the battery load before the array is connected to a load, then charge is transferred from fully charged cells to weaker cells, thereby reducing charge imbalance among the cells. The array is connected to a load and power is drawn from the series array.Type: ApplicationFiled: February 10, 2011Publication date: October 11, 2012Applicant: SENDYNE CORP.Inventor: Ioannis Milios

Patent number: 7936150Abstract: A type of protection and cell conditioning circuit is proposed that partly uses the typically existing hardware present in traditional cell-protection circuits and that can achieve an optimum state of charge for the individual cell independently from the actions of the external battery charger. For minimum cost, the proposed circuit and system can solve the battery-cell-balancing problem, while optimizing the performance of the battery pack and while simultaneously enhancing the safety of the battery pack. Multiple battery cells can be communicatively combined to form large batteries. Information from and commands to each of the individual battery cells can be relayed through a low-power serial bus in order to form “intelligent” and optimally managed battery systems.Type: GrantFiled: February 17, 2010Date of Patent: May 3, 2011Assignee: Sendyne CorporationInventor: Ioannis Milios

Patent number: 7816057Abstract: In a direct methanol fuel cell, fuel efficiency is maintained by periodically adding a higher methanol concentration mixture through a cartridge into the primary fuel container. The cartridge replenishes methanol and partial water losses due to the consumption of fuel in the power generating process. In a typical system, the fuel replenishment mechanism is controlled through an electronic apparatus that monitors the power conversion process and is capable of predicting remaining operating capacity.Type: GrantFiled: January 15, 2004Date of Patent: October 19, 2010Assignee: Sendyne CorporationInventors: Tadashi Okuto, Ioannis Milios
