BATTERY SYSTEMS

We supply various battery systems that enable you to store available energy in the battery that you can use when you need it. The simplest variant is to store excess energy produced during the day. This will then be available in batteries and the energy can be used at night.

We have developed our own power electronics and management of energy systems which enable us to realize the following functions:

ENERGY STORAGE

Energy storage is the easiest way to use battery. The energy is stored in the battery so that the stored energy can be used at a time when there is no access to electricity. For example, in cabins that are not connected to the electricity grid (off-grid), energy will typically be produced when the sun is shining and stored in the battery. This means that in the evening and at night you will have available energy to use from the battery.

DIESEL HYBRID

Diesel hybrid is an energy system comprised of diesel generators and batteries. The generator creates energy which goes to usage as well as charging batteries. When the batteries are fully charged the generators stops, and all the energy used comes from the batteries. When the battery nears its minimal or charge level, the generators restart to refill the batteries.

The benefit of such an energy supply is that the generators will be turned off for most of the day and energy production happens under optimal loading of the generators. As a rule of thumb, a generator produces four times more energy per liter of diesel than the generators running at low loads.






The figure shows how 24 hours can be visualized. The example is from aquaculture and fish farms, in which one has low energy requirements through the night and high usage during the day when industrial equipment is running.

PEAK SHAVING

Batteries that have been used for cutting power peaks are called peak shaving. When there is too little power available from the generator, batteries are used to take the peaks.

You can also use this in connection with the power grid to prevent using more power than you have agreed with the electricity supplier. In this way, high energy prices caused by power peaks are saved.

GRID SUPPORT

Grid support can be a solution when the public electrical grid cannot cover the needs of the area. These are locations where there isn’t enough energy during specific times. The battery will be charged when the energy needs are low or prices are low. When the need is increased, and the need is greater, the battery kicks in to help cover those exceedance requirements.

This is already typical of charging stations for electric vehicles. The electrical grid typically cannot manage to charge many cars at a time, and therefore the energy is stored in batteries which aid when the charging demand is high

EMERGENCY ELECTRICITY

Batteries can also be set up as an emergency energy solution. This means that one is supplied with electricity even if the standard electrical supply should fail. The battery solution can also be used for UPS applications. The reaction time for emergency electricity is so fast that one won’t notice the transition from running normally to emergency supply. Emergency electricity can be delivered with the effects and charging capacity required.
