battery: the energy density of the battery system is about 160~175Wh/kg, the battery capacity is 9.2~26.5kWh, and the battery life range is 120km-300km. The battery comes with a temperature management system and is heated at low temperature.
Currently, there are 8 suppliers of battery, namely Guoxuan Hi-Tech , CATL , Penghui Energy, Honeycomb Energy, Xingheng Power , AVIC Lithium Battery , Ruipu Energy, and Huating Power. Some of them are lithium iron phosphate batteries , and some are ternary lithium batteries.
motor : motor has 27 horsepower and 41 horsepower, corresponding to power is 20kw and 30kw, both of which are permanent magnet synchronous motor . Because the motor itself is not very powerful, it does not use liquid cooling, but is naturally air-cooled.
motor has 3 suppliers: Founder Motor , Shuanglin Co., Ltd. , and Wolong Electric Drive.
electronic control has 2 suppliers, namely: Huayu Electric and Ningbo Yangteng
Tesla Model Y
batteries, currently uses lithium iron phosphate and ternary lithium batteries, with battery capacity of 60kWh and 78.4kWhhh. With battery temperature management system low temperature heating and liquid cooling. battery supplier: CATL, LG Chem. In terms of
motor, uses two solutions: permanent magnet synchronization (194KW 264 horsepower single motor solution) and front induction/ asynchronous motor + rear permanent magnet/synchronous (331~357KW 450~476 horsepower dual motor solution ). is equipped with a three-in-one drive system for driving motors, motor controllers, , and a single-speed gearbox, with high integration.

Zekr 001
battery : The "extreme core" battery pack uses high-voltage single crystal Ni55+ battery cell, is a type of NCM523, and its suppliers are Xinwangda and CATL, all of which are ternary lithium batteries. The battery is characterized by increasing the working voltage of the single unit from 4.2V to 4.35V, thus giving the single unit a larger capacity and an energy density of up to 250Wh/kg. The battery comes in two capacities: 86kWh and 100kWh, both with low temperature heating and liquid cooling.
Motor electronic control: adopts an integrated three-in-one electric drive system with motor, motor controller and high voltage module, which can effectively improve power density and drive efficiency. The maximum power of the dual motor version is 400kW and the maximum torque is 768N·m. The characteristics are high speed and the maximum speed can reach 16500r/min.
