TVS Motor has been granted a patent for a charger device that charges vehicle batteries in two user-selectable modes: power and economy. The device monitors AC line input voltage and adjusts charging current accordingly, transitioning to constant voltage charging once a battery threshold voltage is reached.

Charger device with user selectable power and economy modes
The patent US12068630B2 describes a versatile charger device designed for charging one or more vehicle batteries. This device operates in multiple user-selectable modes, specifically a power mode and an economy mode. In the economy mode, the charger monitors the alternating current (AC) line input voltage and adjusts the charging current accordingly during a user-defined time interval. The device continues charging until a predetermined battery threshold voltage is reached, after which it switches to constant voltage charging until the charging current falls below a specified threshold. The charger is equipped with at least two switches, including a power switch and a mode selection switch, along with a user-adjustable time selection knob to facilitate user control over the charging process.
The claims further elaborate on the functionality of the charger in both modes. In the economy mode, the charger can perform either economy charging, which varies the charging current based on the AC line input voltage, or power charging, which delivers a maximum charging current independent of the AC voltage. The device is designed to ensure that charging is completed within the user-selected time interval, switching between economy and power charging as necessary. Additionally, the charger will cease operation when the charging current drops below the set threshold value. The method outlined in the patent emphasizes the charger’s ability to adapt its charging strategy based on user input and real-time monitoring of the battery and AC line conditions, ensuring efficient and effective battery charging.
