When it comes to powering your AGVs, charge time is more important than runtime and uptime is king.
The drive for higher and higher levels of productivity has caused some AGV manufacturers to select larger batteries that can last longer between recharge periods. This is understandable: more runtime means more time doing work, right? As it turns out that is not always the case. What some end customers and OEM’s may be overlooking is how long it takes the battery to recharge.
To better understand this, let’s first define some things.
- When we talk about runtime, we typically think about the amount of time that an AGV can be operated before the need to charge it.
- Charge time is how long it takes to recharge the battery once it is depleted.
- Uptime is the amount of time the AGV is available to do work over a specified period, for example over 24 hours.
- Uptime takes into account the downtime needed to recharge.
- While runtime is important, what’s even more important is the uptime.
As you can see in the above charts, NEC’s fast charging battery allows the AGV to go from 75% uptime to 97% uptime. That is a 30% improvement in productivity! That’s why at least an equally important question to consider when choosing an AGV battery must be how much charge time is required. Not only does NEC’s battery give you more uptime, it is also likely to be physically smaller and lighter, taking up less precious room in the AGV.
