According to embodiments, provided is an antenna comprising: a substrate of a square shape including first to fourth corners; a radiation unit disposed on the substrate and including a first radiation unit and a second radiation unit that radiate a wireless signal; a first feed line that applies the wireless signal to the first radiation unit; a second feed line that applies the wireless signal to the second radiation unit and has an extension line that perpendicularly intersects with an extension line of the first feed line; and a ground portion disposed on the substrate and spaced apart from the radiation unit and having at least a portion of a boundary area including a step shape, wherein the ground unit includes a shared ground unit that is disposed diagonally from a first edge to a third edge, is located between the first radiation unit and the second radiation unit, and performs impedance matching of the first radiation unit and the second radiation unit.

Antenna and vehicle

Disclosed is a battery management apparatus capable of effectively reducing the current consumption of a component for waking up a microcontroller unit. The battery management apparatus includes a wake-up unit, a first power supply path, a first regulator, a first switching element, a feedback module, and a microcontroller unit configured to convert a sleep mode to a wake-up mode by receiving a wake-up signal from the wake-up unit and connected to the feedback module to turn off the first switching element.

Battery management apparatus

An apparatus and method for preventing overcharge of a secondary battery that prevents the overcharge of a Starting Lighting Ignition (SLI) battery, which can be applied to both a regulated system with a voltage regulator and an unregulated system without a voltage regulator, by regulating the voltage applied to the cell assembly.
