Onboard Charger
Current measurement for optimal charging
Onboard chargers (OBC) are essential components in electric vehicles that enable the vehicle battery to be charged via the power grid. They ensure that the battery is charged safely and efficiently, regardless of the available power source. An important technology in OBCs is precise current measurement, for which Isabellenhütte has the appropriate portfolio.

Precise current measurement for safe and efficient charging using Onboard Chargers
The use of onboard chargers offers flexibility and convenience, as charging can take place at various locations such as at home, at work or at public charging stations.
Accurate current measurement enables monitoring and control of the charging process to ensure that the battery is always charged with optimum efficiency and safety. It helps to accurately determine the state of charge, shorten charging times and extend battery life. Precise monitoring can prevent overcharging and overheating, which increases safety and improves the overall performance of the vehicle.
