Dataset of electric passenger cars with their specifications

This dataset lists all fully electric passenger cars with their attributes (properties). The collection does not contain data on plug-in hybrid cars and electric cars from the so-called “range extenders”. Hydrogen cars were also not included in the dataset due to the insufficient number of mass-produced models and different (compared to EV) specificity of the vehicle, including the different charging methods. The dataset includes cars that, as of 2 December, 2020, could be purchased in Poland as new at an authorized dealer and those available in public and general presale, but only if a publicly available price list with equipment versions and full technical parameters was available. The list does not include discontinued cars that cannot be purchased as new from an authorized dealer (also when they are not available in stock). The subject of the study is only passenger cars, the main purpose of which is to transport people (inter alia without including vans intended for professional deliveries). The dataset of electric cars includes all fully electric cars on the primary market that were obtained from official materials (technical specifications and catalogs) provided by automotive manufacturers with a license to sell cars in Poland. These materials were downloaded from their official websites. In the event that the data provided by the manufacturer were incomplete, the information was supplemented with data from the SAMAR AutoCatalog (link can be found in References section). The database consisting of 53 electric cars (each variant of a model – which differs in terms of battery capacity, engine power, etc. – is treated as separate) and 22 variables (25 variables, including make, model and “car name” merging these two previous).

本数据集收录了所有纯电动乘用汽车及其各项属性（特征参数）。本数据集未纳入插电式混合动力汽车，以及所谓的“增程式”电动汽车相关数据。由于量产车型数量不足，且氢燃料汽车与纯电动汽车（EV）在车辆特性（包括充电方式等）上存在显著差异，本数据集同样未纳入氢燃料汽车。本数据集涵盖2020年12月2日于波兰境内可通过授权经销商全新购买的车型，以及已公开预售的车型；但前提是该车型需公开包含配置版本与完整技术参数的售价表。本列表未纳入已停产、无法通过授权经销商全新购买的车型（包括无库存在售的车型）。本数据集的研究对象仅为以载人为主的乘用汽车（例如，不包含用于专业配送的厢式货车）。本电动汽车数据集收录了波兰授权销售汽车的汽车厂商官方发布的一手市场纯电动汽车相关信息，信息来源包括厂商提供的官方技术规格与产品目录，且相关资料均从厂商官方网站下载获取。若厂商提供的数据存在缺失，则会通过SAMAR汽车目录（相关链接详见参考文献部分）补充完善相关信息。本数据集共包含53款电动汽车（同一车型的不同变体，例如电池容量、电机功率等参数存在差异的版本，均视作独立条目），并收录22项属性变量；若将品牌、型号以及合并二者的“车辆名称”三项单独统计，则总变量数为25项。
