  • Patent number: 12126208
    Abstract: The disclosure relates to a method for adaptively fast-charging a battery pack using a battery charging device. At least one voltage and the temperature of the battery pack are continuously or periodically detected by means of a detection unit. A charging current of the battery charging device is adapted by means of a control and/or regulating unit of the battery charging device on the basis of the detected voltage and/or the detected temperature of the battery pack. At least one battery-specific threshold of the voltage and/or the temperature is taken into consideration in order to adapt the charging current by means of the control and/or regulating unit. Prior to starting the charging process, the battery-specific threshold of the voltage and/or the temperature is transmitted from a memory unit of the battery pack and/or the battery charging device to the control and/or regulating unit by means of a communication unit.

  • Patent number: 12126202
    Abstract: A method detects electrical fault states of a removable battery pack. Cell voltage values of a plurality of energy storage cells of the removable battery pack are detected by a first monitoring unit integrated in the removable battery pack and a voltage of the removable battery pack is detected by a further monitoring unit integrated in an electrical device, in particular a charging device, a diagnostic device or an electrical consumer, that can be connected to the removable battery pack. The cell voltage values detected by the first monitoring unit are transmitted to the further monitoring unit. The further monitoring unit sums the cell voltage values and compares this with the voltage value of the removable battery pack.

  • Patent number: 11314566
    Abstract: In one embodiment, a method includes creating, by a computing device, an inter process communication (IPC) channel for communication from a producer process to a consumer process. The IPC channel includes a message buffer mapped to a first virtual address space of a kernel of an operating system and to a second virtual address space of the consumer process in a user space of the operating system. A sender handle for the message buffer is sent to the producer process. The kernel receives a request, which includes the sender handle, to send a message from the producer process to the consumer process through the IPC channel. Responsive to a determination that the request is permitted, the kernel writes the message to the message buffer using the sender handle, such that message written in the message buffer is accessible to the consumer process through the second address space.
