Note: Due to technological improvements, the above data are subject to change without prior notice.
 

1. Battery life span is 4,000 times full charging, 8 years, how to dispose of it when expired?

Different machinery will have a different life span

4,000 times full charging, 8 years is the life span for the electric excavator  

When the battery expires, there still 70% volume remains and it can be used for energy storage

There will be professional recovery companies soon.

2. Is the CATL battery safe and will not catch fire as incidents happened on electric bikes and electric scooters?

The battery and the battery management system that we use for our electric construction machinery

 is totally different from that are used for electric scooter

The battery that catches fire  is  MnNiCo ternary battery

We use lithium phosphate battery from CATL (also the supplier for Tesla and BMW cars)

The spontaneous combustion temperature of a ternary lithium battery is 200℃,

The spontaneous combustion temperature of lithium phosphate battery is 500-800℃,

and the spontaneous combustion temperature of ternary lithium battery is significantly lower

In addition, the chemical reaction of the ternary lithium material is more intense,

it will release oxygen molecules, the electrolyte will burn rapidly under the action of high temperature, and a chain reaction will occur.

3.We have the following measures to protect our machinery from spontaneous combustion

1, The battery is with cooling and heat management system which guarantees the battery works safely

2, We have software to strictly grade to limit battery overcharge and over-discharge performance

According to the working conditions of the whole vehicle,

formulate corresponding fault protection and corresponding fault handling to ensure the safety of the whole vehicle

3, For our electric machinery  There will be insulation control, which always checks the insulation resistance,

and immediately cut off the high voltage when an emergency occurs.

For spontaneous combustion, we will have a sound and light alarm if a fire occurs
