    Ensuring safety in new mobility



    Intelligence meets safety

    Full of energy for the electric age

    High range, durable and safe: This is the expectation for batteries of the latest generation. The lithium-ion cells enable high energy densities on a small space. Their applications are manifold, from small backup batteries, to large battery packs for electric drives, fitted in cars, trucks, mobile homes, boats or garden tools. However, despite their high performance, lithium batteries react very sensitive to misuse. Needed are solutions that guarantee the long-term, safe and efficient use of these cells. Marquardt delivers: With our innovative battery management systems, cells are continuously monitored, their charge levels measured, data reported to the vehicle or equipment system, and reliable protection provided in the event of an emergency. Whether 12 or 800 volts: With our technological know-how we are a development and production partner for manufacturers of electric drives worldwide.

    Long live the battery!

    The battery is the heart of the electric car – and an Achilles’ heel at the same time. After all, what good is the most powerful lithium-ion battery if it fails or is even damaged due to heat, cold or high loading? For many car buyers, the fear surrounding limited range is the main argument against buying an electric vehicle. But if you want to convince customers, you have to provide answers. Just like Marquardt: the company has developed a key technology for e-mobility with its new battery management systems.
