Swiss battery system manufacturer ecovolta develops standardized 4LR44 battery battery

According to foreign media reports, Swiss battery system manufacturer ecovolta has developed a standardized lithium-ion power battery (Li-iontractionbattery), which can save electric car manufacturers 500,000 euros in research and development costs.

This standard battery greatly reduces the time and cost required to put electric vehicles into mass production. Electric car manufacturers can quickly convert smaller models or previous model series into electrified models and create prototype electric vehicles within a few weeks. Previously, each electric model required a customized battery pack, and the time spent in the process also brought additional risks, and caused electric car manufacturers to be profitable only at a larger production scale. The evoTractionBattery power battery developed by ecovolta has been considered a universal solution that can be put into use quickly.

In addition, such standardized batteries reduce the cost of electricity storage per kilowatt-hour, lowering the entry barrier for companies to enter the field of electric mobility. The integrated battery management system enables master-slave operation, as well as connecting the battery to the CAN bus, allowing the battery to exchange data with a higher-level control system, which is essential for the safety and efficiency of vehicle operation. In addition, the system also integrates safety technology, relays and pre-charging technology.

The evoTractionBattery power battery has a voltage of 24 volts, 48 volts and 400 volts, and a capacity from 2.5 kWh to 15 kWh. In any configuration, up to 16 such batteries can be connected in series and up to 32 such batteries can be connected in parallel, with a battery voltage range of 24 to 829 volts and a total capacity of up to 7,600 kWh. Each battery module has a fixed length of 520 mm and a width of 218 mm, while the height depends on the battery voltage and capacity, providing clear parameters for vehicle design. In addition, the customized high-capacity battery systems and electric mobility solutions produced by ecovolta do not require active cooling.
