Automotive battery

The use of Lithium batteries in cars, motorcycles, heavy vehicles and off-road equipment is increasing rapidly. Lead Acid batteries are being replaced by Lithium batteries to improve charge/discharge performance, save weight, save space, increase lifetime and avoid Pb (lead) in the environment. Within these industries different types of batteries are used. The main categories are: 12V starter batteries, 48V batteries (new board net standard) and EV batteries. Super B is specialized in the 12V and 48V solutions.

Lithium batteries vs conventional batteries: Some numbers

  Up to 80% weight saving

  Charge and discharge at high currents: Charging times of 5 minutes can be reached.

  Our automotive batteries offer phenomenal starting power and massive deep cycle reserve power. They are capable of providing engine cranking pulses of 2250 amps for 5 seconds!

  Longer lifespan with a minimum of 5 years' service life, up to 10 years depending on use

  Our Lithium Iron Phosphate technology with BMS offers enhanced safety compared to traditional lithium iron battery types as well as Lead (Pb) batteries

Super B Lithium Iron Phosphate starter battery
Motorsport has long served as a proving ground for developing and improving vehicle technology. A lot of racing series provide an ideal research and development platform for pushing the boundaries of mainstream vehicle technology. At present, research into rechargeable Lithium Iron automotive batteries is being driven mainly by the requirement in the automotive industry for long service life and charge lifetimes, high discharge currents, the need for rapid charging, and, additionally, cost targets.

While Lithium Iron Phosphate has helped reduce the weight of automotive batteries, it has also helped bolster safety. Safety is extremely important and therefore Super B uses the safest Li-ion technology available: Lithium Iron Phosphate. Thorough testing of all our batteries is carried out in accordance with current legislations and we meet all relevant type approvals like UN 38.3, for full reference see Certificate of Compliance.

Advanced Automotive Battery
Super B’s lightweight automotive batteries have been developed for a number of applications ranging from motorbikes to military trucks. Our existing customers include car manufacturers like Renault, Aston Martin, several military contractors and many more. Super B possesses several patents on the complete battery design.

Reliable Starter Batteries
In addition to standard solutions, we offer customer specific dedicated developments for higher volume projects. The long term Lithium battery expertise of Super B leads to innovative improvements for your energy storage: Best in class reliable battery designs at very competitive cost.

48Volt built for OEM
Building on the success of the 12 volt technology, Super B has been at the cutting edge of nominal 48 volt developments so you can take full advantage of our Lithium Iron technology in your designs. Introducing 48V systems will help comply with stringent CO2 regulations and fuel saving by introducing mild hybrid 48V systems and reduce (cabling) weight. Super B can assist engineers of global car manufacturers to produce a vehicle application suited to their individual needs.

Features & Benefits of the 48 volt system:
• Scalable packaging solutions to optimize for your capacity and envelope needs
• Best in class efficiency, lowest self-heating. Solutions possible without active cooling.
• Integral BMS/switch/fuse with very accurate State Of Charge management.
• Standard CAN or LIN interface to vehicle for battery monitoring, switch control and diagnostics.
• Development according automotive standards including ISO26262 functional safety, AutoSAR etc.

Large marine battery banks store a huge amount of energy, and this needs to be treated with great care. Because Super B believes Safety comes first in any marine application, we base our batteries on Lithium Iron Phosphate Technology (LFP), the safest lithium technology available today with superior abuse tolerance. Our technology avoids the risk of self-combustion or in extreme cases even explosions known from other Lithium technologies. Next to our inherently safe LFP battery technology, our batteries have advanced secure internal electronics with integrated temperature and current sensors to continuously monitor and report the state of the battery.

BMS / Battery Communication Interface / PLC code
By improving the conventional BMS and implementing the Battery Communication Interface and PLC code for the integrators switchboard, the next step in battery integration has been realised. This provides flexible ‘plug and play’ solutions which are cost and time effective – delivering safe, powerful yet reliable, low maintenance results. All batteries can be interconnected and act as one big battery system – Scalable configuration options are endless.

High Energy Density
Super B cherishes your precious energy by offering best in class efficiency compared to other technologies. Battery energy management reaches more than 96 percent efficiency, which not only saves valuable energy but also minimizes self-heating of the battery systems, further increasing lifetime and safety.

Long Lifespan & Best TCO calculation
Super B has a team of experienced engineers and system integrators that will help tailor a battery solution for your specific large marine project. We can calculate all the trade-offs for you based on your usage profile, lifetime needs in your application, capacity need, initial cost and system integration. Our mutual goal is to achieve the lowest possible TCO and the best investment strategy for you as our valued customer.

In large marine projects, Super B can pre-build and pre-test the battery systems to allow easy plug and play installation on the ship. This avoids a trial and error approach on the ship itself, simplifies system integration and shortens integration time on board.
