Safe performance – designed down to the last detail for the most demanding use
Lithium-based batteries are the technology of choice for electric mobility applications. They store significantly more energy than all other batteries. They maintain a high current, which is a major advantage for electric drive systems. They do not lose their charging capacity and they supply power reliably even in the cold and have no memory effect. They also provide many more cycles than lead-based batteries.
Torqeedo has been a pioneer in the development of lithium batteries for boat applications for ten years. Since we make our batteries just a little bit better each year, we offer the most comprehensive and integrated protection and safety concept for lithium batteries on the market – coupled with outstanding performance and convenience.
Lithium Battery Safety
Aside from performance, safety plays an important role for lithium batteries. In our view, five influencing factors need to be considered in order to ensure that safe really means safe:
Clean, precision production processes on the part of the cell manufacturers. Torqeedo only uses cells sourced from reputable manufacturers in Japan and the USA.
Waterproof to IP67: water in lithium batteries can lead to various problems such as corrosion of the BMS hardware or the creation of electrolytic gas. Lithium batteries on board a boat should therefore be waterproof.
Safe battery chemical engineering, e.g. LiFePo (lithium iron phosphate) or LiNMC (lithium nickel manganese cobalt oxide). These are now widely used.
