A cooking plate includes a metal plate for cooking; a heating element, which is in contact with the metal plate and is configured to heat the metal plate; and a temperature sensing element which is integrated with the metal plate and which is configured to sense a temperature of the metal plate and outputs a sensing signal for control heating of the heating element.

Cooking plate with temperature sensing element

A battery management system (BMS) used in a battery pack, the battery pack has a discharging switch coupled between a battery and a load, and the load has a capacitor charged by the battery pack. The BMS has a driver circuit having a power supply terminal to receive a drive voltage, a ground reference terminal coupled to receive the battery pack voltage and an output terminal coupled to a control terminal of the discharging switch. The BMS generates a normal drive voltage and a ramp drive voltage, and the normal drive voltage is selected as the drive voltage when the voltage difference between the battery voltage and the battery pack voltage is less than a threshold voltage, and the ramp drive voltage is selected as the drive voltage when the voltage difference between the battery voltage and the battery pack voltage is higher than the threshold voltage.

Battery pack and discharge method for limiting an excessive discharge current

In one embodiment, a fuel gauge system is described that comprises two or more battery chargers on different integrated circuits (ICs) coupled in parallel to a battery for charging the battery. Each battery charger IC generates a current signal indicative of current generated by said each battery charger IC into the same battery. A fuel gauge is responsible for accurately reporting the battery state of charge, based on a combination of voltage, current, and temperature information.

Battery fuel gauges sharing current information between multiple battery chargers

A system for estimating battery state of charge (SoC) includes evaluating a battery model to produce an estimated battery voltage using a previously produced SoC. Current and voltage measurements are combined with the estimated battery voltage to produce a present battery SoC. The battery model may be updated by taking battery measurements when certain conditions occur.
