Instructions for use of CTS pure electric buses

Instructions for using pure electric vehicles in winter are as follows:

At present, the energy system of pure electric buses is mainly lithium-ion batteries. Due to the limitations of their chemical properties, lithium-ion batteries have lower low-temperature performance than The normal temperature is poor, which means it is not suitable for large current charging and discharging. In this case, there will be some changes in the low-temperature performance of the vehicle

Dynamic issues: Due to the reduction in battery discharge capacity, the output current during driving becomes smaller and the vehicle power becomes worse.

Reason: This situation usually occurs when the first train departs in the morning. Because the battery temperature in the morning is lower than that during operation during the day, the driving range and power consumption are affected.

Problem: In low temperature environments, the battery will turn on self-heating to meet the vehicle's operating requirements. At the same time, due to the reduced battery charging capacity at low temperatures, the braking energy feedback of the vehicle is reduced.

Reason: The power consumption of the vehicle increases accordingly, and the driving range decreases accordingly. On the other hand, in order to prevent slipping, when the vehicle turns on the ice and snow mode, the braking energy feedback will be reduced, which will also affect the vehicle's performance. Increased power consumption and reduced driving range
