Torqeedo Lithium Batteries Charger and Switch

Torqeedo lithium batteries, charger and switches

Lithium-based batteries are the technology of choice for electric mobility applications: they store significantly more energy than other batteries, delivering their capacity even under high loads – a very important benefit for electric propulsion; they don’t lose their charge, work in the cold and have no memory effect. plus, they deliver more cycles.for 7 years, Torqeedo has continually led the way in marine lithium battery development. improving their batteries every year, they have created the most comprehensive protection and safety concept for marine lithium batteries on the market – bringing together performance, safety and comfort.

Along with performance, safety is a key requirement for lithium batteries. based on 4 requirements that a safe lithium battery must fulfill:

1. Safe battery chemistry,  

2. Safe packaging of individual cells: Torqeedo uses only safety cells, i.e. welded steel cylinders equipped with multiple safety mechanisms. alternative packaging – foil-welded cells – offers a reduced safety standard because they don’t provide effective protection against internal short circuits of the cells (exceptions are foilwelded cells with ceramic separators, which provide safe packaging but are fairly rare). 

3. Precise and clean production processes at the cell manufacturer level: Torqeedo only uses cells produced by renowned manufacturers in Japan and the usa.

4. Battery-Management-System (BMS) with redundant safety: unlike lead-based batteries,
lithium batteries generally need a bms to perform balancing and safety functions. if electronic components in the bms fail, the bms can itself become a safety problem. which is why, with Torqeedo, all safety-relevant components are duplicated, the same way it is done in the automotive, air transport and medical industries.
