Traction battery for driving lifting device of battery-electric truck, has several single cells which are designed as lithium battery, where each single cell has specific capacity

摘要

The traction battery (1) has several single cells (3) which are designed as a lithium battery (2), where each single cell has a capacity in the range of 20-70 ampere hours. The lithium battery is Li-ion battery, lithium polymer battery, lithium titanate battery, lithium iron phosphate battery or lithium-air battery. The cells are switched in parallel or series in order to obtain a desired total capacitance value. Each cell module is provided with a monitoring device comprising controller, temperature sensor and/or voltage sensor. An independent claim is included for traction battery system.
