Case N.C. Nielsen is now ready with the second generation of its proprietary Lithium-ION batteries. After five years of on-site production and more than 1,600 batteries delivered to its customers, N.C. Nielsen has now taken a giant leap and has developed a brand-new type of Lithium-ION batteries, pushing the boundaries for capacity, performance, life, temperature sensitivity and sustainability.

N.C. Nielsen continues to use Lithium LFP cells. They have high energy density, long life, an optimum weight relative to output and optimal safety as, among other factors, they do not contain cobalt. Practical experience shows that internal resistance of battery packages is so low that very efficient charging and discharging of the batteries can be ensured. Thus, energy savings of more than 70 % are obtained compared to conventional lead batteries.

 

Double capacity - same physical framework

The previous Lithium-ION batteries have a battery capacity of min. 80% after 3,000-3,500 charge cycles. N.C. Nielsen has doubled the number of charge cycles to 6,000-7,000 before the battery reaches 80 % of the original capacity. The improvement has occurred within the same physical framework, using thermal battery management and a mechanical construction where the battery is kept under pressure during installation.

- We insist on constantly developing our battery technology and have gained valuable experience from our customers. We have considered all key factors and asked ourselves what we could do better. We have developed the new generation of Lithium-ION batteries in close co-operation with external experts and have come far ahead of all other technologies in the market, says Per T. Nielsen, Technical Manager, N.C. Nielsen.

 

Monitoring around the clock

N.C. Nielsen has developed a new BMS system (Battery Management System) that constantly gives very accurate information about the charging and health of the battery. Data can be read out to help the customer optimise the battery operation to an even higher degree.

At the same time, highly improved balancing has been obtained to utilise capacity and extend life. Previously, it was necessary to fully charge Lithium-ION batteries at least once a week as the battery performed balancing at the end of a full charge cycle, but balancing is currently performed when starting charging - also for booster charging. The battery will then always be at the highest level and provide maximum performance.

 

Tolerates large fluctuations of temperature

Previously, a Lithium-ION battery from N.C. Nielsen was able to operate at temperatures between -20 to +45 degrees C. Significant improvement has occurred in that area as well. The new batteries are able to operate in environments from -30 to +60 degrees C without difficulty. This means that the battery cells can now be used in more types of industries and trades.

 

Ready for peak loads

Previous versions of Lithium-ION batteries were able to manage peak loads corresponding to C1 for 10 seconds. The new generation of Lithium-ION batteries can easily manage peak loads corresponding to C2 for 60 seconds. This means that the machine can be used more intensively, and capacity be utilised even better. In other words, twice as many amps can be pulled out of the machine six times as long as previously.
