2020 Bolt EV Battery Updates Add to Electric Range

Starting with model year 2020, the Bolt EV will offer an EPA-estimated 259 miles (417 km) of range on a full charge, a 21-mile (34 km) increase over previous model years. With the increased range, the 2020 Bolt EV (Fig. 1) will appeal to even more customers by allowing them to travel farther between charging sessions.

The new high voltage battery pack capacity (Fig. 2) is 66 kWh, up from 60 kWh in previous model years. Proprietary improvements in both cell design and manufacturing contribute to the increased capacity. SAE Level 3 DC fast charge rates are also improved for 2020, especially in cold weather, reducing the amount of time spent at a charging station.

高电压电池组、档次e

全电池组和所有五个电池部分将通过在美国和约克Esc在加拿大的通用汽车服务中心（GM BSC）推出2020螺栓EV。新电池组和部分在外面看起来相同。然而，新的N2.2化学2020的化学与2017-2019螺栓EV模型之前的N2.1化学不兼容。

TIP:在订购和安装电池组之前，请务必确认修复的正确部件号。有关订购电池组和＃18-NA-236，请参阅公告＃19-NA-194进行订购电池组。

EV系列

With the increased EPA label range comes the potential for more customer questions about EV range variation. As with all GM plug-in vehicles, the displayed EV range is an honest estimate based on driving techniques and terrain, ambient temperatures and climate control settings, and battery factors.

当螺栓EV仪器集群上显示较低的EV范围（图3）时，一些客户可能对他们的车辆电池的存储容量失去了一些信心。GM使用螺栓EV电动和混合保修后备各电池组。在北美，如果电池组在8年或100,000英里/ 160,000公里处（以先到的）EV保修期限超过其容量的40％以上，则可以为客户替换电池组。

检查19-NA-210，了解有关新工具，服务程序和诊断辅助工具的亮点，了解为什么范围估计低于螺栓EV上的预期，LDSPORTS下载以及电池组修复是否会增加EV范围。这些诊断辅助辅助装置中的一些也适用于某些伏特，火花EV和CT6 PHEV车辆。在适当的服务信息中搜索“减少EV范围”，了解有关影响EV范围的因素的更多信息。

A new data screen in GDS2 is available under the Hybrid/EV Powertrain Control Module 2 entitled Energy Usage History. Some of the new information available includes the battery capacity in Amp-Hours and the energy impact score from several factors, such as outside temperature, cabin climate, and driving technique.

Share the energy usage data with customers to help better their understanding of why the EV range estimate may be lower than expected. The goal is to increase customer confidence and minimize concerns due to the fluctuations observed in the EV range estimate.

Action Center

技术援助中心（TAC）行动中心已经在2020螺栓推进系统上为产品反馈建立，以帮助确保成功介绍。报告任何推进或充电问题，要求提示和立即关注，而不仅仅是需要技术援助的担忧。

The gathering of information is critical for quick resolution to any propulsion-related concerns. The Action Center is connected directly to TAC and Product Engineering to address any technical concerns.

要报告一个问题，请使用经销商案例管理（DCM）系统（U.S.）创建TAC案例。关注的是螺栓EV专家回答。在加拿大，联系加拿大TAC。
