We'll be happy to explain the Miba FLEXcooler^®to you.

Suitable for all cell types, forms and sizes

Our flexible battery cooling is compatible with every cell type on the market, whether pouch, prismatic or cylindrical cells of all formats.

The same applies to the cooling direction. The Miba FLEXcooler^® can be integrated to cool the bottom, pole, tab or side of any type of battery cell. Once the FLEXcooler^® has been integrated in the selected cooling direction, it inflates due to the coolant flow in its flow field until a positive connection is made between all surfaces to be cooled, without the need for TIM or other filling agents.

New approach to battery cooling

Thermal management is a critical success factor for electric vehicles. Long service life, short charging time and energy density are directly related to an efficient battery cooling system.

Traditional battery cooling takes the form of a plate, usually made of aluminum, with embedded channels for the coolant. The battery cells, which are usually surrounded by a metal sleeve, and the cooling plate are rigid. Direct contact - e.g. due to manufacturing tolerances - always results in an air gap and thus poor thermal conductivity. By adding thermal conductive pastes, good thermal coupling can be achieved at this point.

Miba's flexible battery cooling system now replaces the cooling plate with a heat exchanger that adapts to the shape of the battery cell. The flexibility of the heat exchanger enables direct thermal contact between the heat exchanger and the battery cell, even without the use of a heat-conducting paste.

Joint work in battery initiatives - Battery cooling as an essential part

iModBatt stands for an industrial modular battery concept, with high energy densities, environmental friendliness, flexibility and cost efficiency for automotive applications. The goal of iModBatt is to create a battery that meets the most modern demands. The production and design should be as environmentally friendly as possible, while the battery itself delivers high performance and is flexible enough to be used in cars or small stationary applications.

iHeCoBatt — i-HeCoBatt stands for an Intelligent Heating and Cooling solution for enhanced range EV battery packs. The aim of i-HeCoBatt is to achieve a smart, cost bursting industrial battery heat exchanger to minimize the impact on full electric vehicle range in extreme conditions. Smart, because new sensing functionalities will be embedded to the thermal system in order to monitor the behavior of the whole battery pack thermal system. Cost bursting, because components of current state of art products will be replaced by even more cost-efficient components as well as the number of parts minimized. Industrial, because mass production means will be used to manufacture the heat exchanger.

One of the EU Commission's important strategic goals is to establish competitive European battery production. To this end, it has launched the European battery initiative "EuBatIn". Of the only six Austrian companies in the initiative, Miba Battery Systems and Miba Battery Components are part of the project to establish European battery production.

Our Experts

Our flexible battery cooling adapts perfectly to the battery cell housing, even if the hydrostatic pressure of the cooling circuit is only 0.05 bar. This results in efficient thermal coupling. Since a gap filler is no longer needed, weight is saved and a fixed connection between the heat exchanger and the battery modules is also avoided. This makes it realistic for the first time to easily separate battery and heat exchanger for recycling and repair purposes.
