Batteries for overnight charge
Batteries designed for overnight charging ensure full-day autonomy, which demands high energy capacity, reliability, and durability.
WATTALPS batteries provide certified safety, energy savings to operate, and long-life for maximizing your return on investment.
If your application requires overnight charging and high energy density, you should consider the following key challenges when selecting a battery.
Key challenges for batteries for overnight charge
Thanks to our battery solutions based on immersion cooling technology, we have helped our customers address these challenges successfully.
Energy density
Energy density is the key parameter for this application.
Safety
Safety is paramount, requiring advanced protections against overvoltage, short circuits, and thermal risks.
Thermal constraints
Managing thermal constraints is critical, as cell chemistries with highest energy densities are generally the ones with highest sensitivity to temperature. These cells lose a lot of capacity in cold temperatures and age much faster when used outside their optimal temperature range (15 to 30°C).
Why choose WATTALPS batteries for overnight charging
Certified safety
Learn more on:
⊕ Battery safety
WATTALPS batteries are engineered to meet the industry’s most rigorous safety standards and are certified against fire risks. For more details, explore our dedicated battery safety section.
Energy savings
Thanks to our immersion cooling technology, the fluid stabilizes the battery temperature. Our batteries are preconditioned to the optimum temperature while being charged, using energy from the grid to store heat in winter or coolness in summer. This removes any need for additional energy to control battery temperature during use, enabling up to 5% energy savings.
Life increased up to 2 times*

⊕ Temperature control
Battery life is highly dependent on the cell temperature variation during operation. Going beyond 45°C reduces battery life by 66%. Our patented immersion cooling technology provides superior temperature control, enabling stable, reliable long term operation, and a lifespan up to two times longer than conventional lithium batteries for this application*.
