What is a Marquardt high voltage box?

The Marquardt High Voltage (HV) Box is a self-contained Battery Management System (BMS) designed to optimize battery performance and safety. With advanced, high-quality components, rugged durability and compact size, it’s what you want to drive your next EV project.

What is a battery management system (BMS)?

Every single watt-hour stored and retrieved from the cells is critical to extend the driving range. The main function of a battery management system (BMS) is to monitor cell voltages, pack voltages and pack current.

Why do we need a battery pack monitor?

The massive electrification efforts happening in the automotive industry are driving the need to reduce the complexity of BMS by adding electronics in the junction box, while enhancing system safety. A pack monitor can locally measure the voltages before and after the relays, the current through the battery pack.

What is a battery management controller (BMC)?

Ensure optimized, efficient battery protection and performance with the integrated Battery Management Controller (BMC) in our HV Box. It significantly extends battery lifespan, so drivers experience fewer disruptions and eliminate the cost of frequent battery replacements.

How does a BMS calculate power and impedance?

Calculating the impedance of the cell by measuring the voltage, current and power across the cell enables the BMS to monitor the instantaneous power of the car. The cell voltage, pack voltage and pack current have to be time-synchronized to provide the most accurate power and impedance estimations.
