Batteries & chargers 42 Ring has expanded its professional battery care range with the JUMPSTART PRO 3000 (RJST3000) portable lithium jump starter. The RJST3000 is 12V and 24V compatible and will jump-start all petrol engines and up to 13L diesel engines, which makes it suitable for a wide range of vehicles, including heavy-duty trucks and tractors. The unit has been designed to be tough and simple to use, so jobs can be done quickly. The interface uses easy to navigate lights to signify the different modes and battery status. There is also a warning light that alerts the user if there is an issue with the connection. A solid light indicates reverse polarity protection, and a flashing light indicates temperature protection. Auto voltage detection ensures safe operation across different vehicle types. A boost function is able to revive completely flat batteries, reducing downtime for customers or fleets. The unit weighs just 3kg, making it easy to carry, while the built-in clamp holders are ideal for storage and keep the wires tidy and safe. Additional features include a bright LED light, which allows the unit to be used in varying light conditions. It can also be used as a powerbank, in case the user needs to charge their phone to call for assistance. www.ringautomotive.com FORVIA HELLA has launched its first fully integrated 12-volt lithium-ion battery pack to address the increasing demand for a reliable and intelligent low-voltage power supply in electric and hybrid vehicles. By integrating lithium-ion cells and the battery management system, the battery pack is said to be able to reduce both weight and system complexity while also increasing the safety and reliability of the vehicle’s energy supply. The 12-volt battery pack uses stateof-the-art multidimensional algorithms that precisely measure current, voltage, temperature and other parameters. This enables highly accurate determination of both the state of charge (SoC) and the state of health (SoH) even under demanding real-world conditions and across the entire battery lifetime. Integrating lithium-ion cells and the battery management system into one subsystem also reduces the required installation space and simplifies system interfaces. This enables simpler and more flexible integration into the vehicle architecture. In addition, the 12-volt battery pack is around 20% lighter than conventional lead-acid batteries. Together with a high-voltage DC-DC converter the 12-volt battery pack enables a redundant power supply for safetyrelevant functions up to ASIL D. The highvoltage DC-DC converter initially supplies the 12-volt loads as the primary source from the high-voltage on-board network. If the high-voltage on-board network fails, the 12-volt battery pack will take over to ensure an uninterrupted power supply. www.hella.com/en 12-volt Lithium-Ion battery pack for electric and hybrid vehicles Portable lithium jump starter
