Abstract: An apparatus includes a battery pack with N battery bricks, each with a DC output voltage. The output of each brick is connected in series providing a bus voltage. Each brick includes battery power modules (“BPMs”) connected in parallel and each connected to a battery cell. Each BPM charges/discharges the connected battery cell. Each brick has a battery brick controller that provides a control signal to each brick's BPMs. A control signal of a BPM is derived from a BPM error signal that includes a battery cell current of the battery cell of BPM subtracted from a summation of an average current signal, a local droop current and a balancing current. The balancing current is based on a current SOC of the battery cell connected to the BPM and a desired SOC for the battery cell connected to the BPM. A BMS derives the balancing current for the BPMs.

Abstract: The present invention relates to a lithium secondary battery manufactured by forming a negative electrode free battery and then forming a lithium metal on the negative electrode current collector by charging.
In the lithium secondary battery, since lithium metal is formed on the negative electrode current collector in the state of being blocked with the atmosphere, the generation of the conventional surface oxide layer (native layer) formed on the negative electrode does not occur inherently, thereby preventing the reduction of the efficiency and lifetime characteristics of the battery.

Abstract: A shareable battery pack for a portable ultrasonic apparatus, a trolley, a power supply system, and a portable ultrasonic system. The trolley can be connected to the portable ultrasonic apparatus and/or the shareable battery pack to supply power so as to extend operation time. Alternatively, the trolley is used to support the portable ultrasonic apparatus and/or the shareable battery pack without supplying power to extend operation time. In an embodiment, the shareable battery pack can be removed from the trolley, and then be fixedly connected to the portable ultrasonic apparatus to form an integral unit and serve as an external battery for the portable ultrasonic apparatus. Such design enables the portable ultrasonic apparatus to have extended operation time without relying on the trolley and requires only one shareable battery pack in special situations, thereby enhancing convenience of use.

Abstract: A method for charging or discharging a battery system, wherein the battery system comprises at least two battery cells connected in parallel and/or in series, which can only be charged or discharged together. A voltage is controlled as a control variable by a current or a power as a manipulated variable. The current or the power is specified by taking into account a first state of charge-dependent characteristic curve and a second state of charge-dependent characteristic curve. The first state of charge-dependent characteristic curve and the second state of charge-dependent characteristic curve have opposite gradients, at least in sections. An apparatus for charging or discharging a battery system is also provided.
