Battery systems

The traction battery module is located underneath the seats. Here, the module is well protected and ideally placed from a safety point of view. This gives a good distribution of weights between the front and rear axel, and provides the vehicle with a very low centre of gravity.

The battery compartment can accommodate different types of battery systems. Currently, TH!NK city features three battery options, two different lithium-based (Li) systems and one sodium battery system.

Sodium batteries: Zebra

The Zebra (Mes-Dea) battery has high energy density, and provides long range performance, independent of ambient temperature. It is a “hot” battery, which means that the operating temperature is between 260 and 360 degrees. The battery is also made from environmentally friendly materials. This option is perfect for users who have a regular and frequent usage pattern. Active materials in the Zebra battery are sodium and nickel. The hot materials are contained in a vacuum insulated and sealed container. Thus, these batteries operate very efficiently in areas with very hot and very cold climate.

Lithium-based systems: A123 and Enerdel

TH!NK city will also come with two state-of-the-art lithium-based battery options. Both lithium options operate at ambient temperatures. This means that the car does not have to be plugged in when not in use. Think is currently co-operating with two suppliers of lithium-based battery systems; A123 Systems and Enerdel.

The Mobility Pack : A monthly fee with ”Batteries Included”

We will own the battery, and take full responsibility for its performance: The customer will only pay a monthly mobility fee (of typically EUR 200) which includes a full maintenance service agreement, carbon offset payments and in some countries even all electricity used, and insurance. In other words, customers can drive with the peace of mind that everything is taken care of. We will continue to take responsibility for battery performance throughout the cars life span, (and exchange the battery when necessary). We also provide body panels which are practically indestructible and do not rust, dent or fade over time. This means that the car will remain “young and agile” throughout its lifetime, and the re-sell value of the car will remain very high, as we have experienced with over 1,000 previous models of the TH!NK city car that still exist on Scandinavian roads.
