Flat & Kube: innovative and powerful batteries

The Flat & Kube range is made up of sustainable batteries with unique sizes and shapes as well as exceptional energy capacity. Aimed for applications requiring high power like electric mobility, these are the largest lithium batteries made by TYVA Energie.

Flat & Kube batteries both have 2 similar power levels but they can be differentiated by their size and shape: the Flat casing is long and thin while the Kube one is a higher square. Both of our compact and innovative batteries include Moduloo Ax’s technology allowing them to be powerful and modular. They are build inside resistant and waterproof aluminium cases.

Many possibilities of the Flat & Kube range

Flat 7 & 12

Innovative Flat batteries are the finest one on the market with a thickness of 10 cm only. Their unique compacity, as well as their light and rigid aluminium casing allow their easy integration and setting inside an electric vehicle.

They also have external convenient mechanical fasteners in addition with TYVA Energie’s smart BMS technologies inside the battery.

Finishing touches: IP65 or IP67 aluminium waterproof casing with a 3000 V tolerability
Removable access panel
Flat version: 100 mm only
Discharge temperature: – 20 °C to + 60 °C
Charge temperature: – 20 °C to + 45 °C

Kube 7 & 12

Compact Kube batteries have a strong and waterproof aluminium casing which is larger and more massive while it is still easy to integrate inside the final product.

They are also fitted with TYVA Energie’s BMS and several mechanical fasteners. Kube are geniune condensed power which can weigh up to 65 Kg.

Removable access panel
Series or parallel assembly connection
Discharge temperature: – 20 °C to + 60 °C
Charge temperature: – 20 °C to + 45 °C

Custom Flat & Kube

Our Flat & Kube range can also be personalized in its casing and power like Moduloo Ax lithium batteries, in order to obtain a custom battery solution that perfectly fits with your application field.

Thus there are many things we can modulate for a reduced development cost: vary the battery’s final dimension, change its power and signal connectors and add a cooling system for example. Once more, we offer you a modular battery allowing various voltage and operating capacity depending on your needs.
