Lead-acid Battery State Sensors (BSS)

Lead-acid battery state sensors monitor battery charging / discharging current, voltage and temperature with high precision, and provide battery information that is important for automotive energy management. They contribute to prevention of battery rundown, improved fuel efficiency and reduction in CO2 emissions through the charging control and idling stops

Junction Boxes with
Semi-conductor Power Devices

By replacing mechanical relays with semiconductor switches, we provide added value such as improving high-precision circuit protection, current suppression through pulse width modulation, silence, and toughness not available with conventional junction boxes.
