Energy Storage Management

In house battery manufacturing

Our energy management and storage solutions, developed and manufactured in our Aduna plant (Guipúzcoa), are designed to cover the needs of today’s European market and to offer the best solution for each of the operator’s requirements.

We offer different modular solutions, based on Lithium-ion technology:

- Slow charging (Energy Pack): Designed so that the vehicle can travel the maximum number of kilometres and complete the operation with a single daily charge. Its design enables us to find balance between vehicle range and number of people.

- Fast-charging (Nano Pack): The perfect coupling of vehicle range and charging capacity. Ideal for mixed operations, where the vehicles has sufficient battery life to operate during peak hours. The load can be both slow and fast.

- Ultra-fast charging (Power Pack): The solution for a 24/7 operation with charging of up to 600 kW.

Our Irizar battery packs are modular and incorporate liquid cooling systems that enable the service life of the batteries to be optimized and make it possible for the vehicles to operate in extreme weather conditions. They meet the latest European regulations on electrical, thermal and mechanical safety: R100.v2, R10.v5 and UN38.3.

We work with customers to study their needs so that we can provide the best solution within our range of different types of pack.

Our battery pack is highly recyclable. We use a controlled process to ensure that all its components are processed and we assess whether or not it can be used in other types of applications.

Second life batteries

Our batteries will get a second life and will duplicate their useful life via the collaboration agreement we have signed with Ibil. Through the collaboration, after their useful lives in buses has ended, our batteries and the power electronics will be reused as storage elements in the electric vehicle charging stations that Ibil is deploying in Repsol service stations.

Batteries are the most fundamental part of an electric vehicle. The range, price, charging speed and useful life of the vehicle depend on them. The useful life of batteries can reach 15 years for urban electric buses, because they are charged daily and at high power. After that time has passed, the accumulators need to be replaced in order for the vehicle to maintain its original functionality. The end of the first life, however, does not mean that the batteries have lost all their charging capacity. So, far from discarding the batteries and in service of their commitment to the environment and the circular economy, sustainable reuse in charging station storage applications will be introduced for stabilising energy demands when vehicles are charged at high power.

We have the solution to this situation. Batteries with a second life can be installed in Ibil charging points to store energy such that it can be used to achieve the following goals. It can reduce the power needed from the electrical grid, thus bringing down both operation and infrastructure costs. And it also makes it possible to deploy high power charging infrastructures, even in places where connecting to the electrical grid is more costly and complex. In addition, with that kind of charging infrastructure using storage back up, distributed photovoltaic power generation can be integrated into the system to generate power locally.

Electric Powertrain

Unlike other projects which are constrained by more standardised motors, the motorisation of the vehicles has been developed using own-brand technology that is developed exclusively for our products so that it adapts perfectly to the products’ requirements.

Doors and climate control

The electric climate control system is designed specifically for zero-emission electric vehicles. The vehicles have been equipped with electric or manual doors and ramps developed by companies belonging to the Irizar Group.

Assisted driver system

This system enables safe communication with the driver which helps them to be more efficient, improving their daily work as well as the service provided to the passengers. This solution assists the driver when approaching stops, at stops and when pulling out. It also improves safety, comfort and punctuality.
