The invention relates to the field of energy accumulator design. A traction battery for a highly automated autonomous vehicle includes: a housing in which modules connected in series are mounted; a heating system comprising a heating mat disposed between the modules; and a control system. The modules are arranged in two layers. Each module includes lithium iron phosphate-based rechargeable cells interconnected in series that are electrically isolated from each other. And the control system comprises a temperature sensor and a humidity sensor which are arranged on each module, a voltmeter for each battery cell in the module, and a current sensor for loading and unloading the power supply module. The invention makes it possible to increase the nominal voltage and operating temperature range during discharge, and to provide safer maintenance of the traction battery.

    本发明涉及蓄能器设计领域。一种用于高自动化自动驾驶车辆的牵引电池包括:壳体,其中安装有串联连接的模块;加热系统,包括布置在所述模块之间的加热垫;以及控制系统。模块布置成两层。每个模块包含彼此电隔离的串联互连的磷酸铁锂基可再充电电芯。控制系统包括安装在每个模块上的温度传感器、湿度传感器、用于模块中每个电芯的电压表以及用于上下电源模块的电流传感器。本发明使得在放电期间增加标称电压和工作温度范围,并且提供牵引电池更安全的维护成为可能。
