The Charging Conundrum: Charging Vs Swapping. What Will Win The Consumer?

Customer needs to find real value in the proposal. It’s not only about changing times but also about changing expectations

The world is moving towards electric mobility. Governments are coming out with ambitious targets, companies are investing in technology and capabilities, newer businesses are looking for a share of the pie and organizations are publishing reports that proves the rationality of this inevitable shift.   

Although facts and figures suggest the increasing adoption of battery powered automobiles, the concern about a feasible way to distribute energy to these devices lingers around. The real question to ask is: how can companies box a commercially viable proposal and establish competitive advantage in this non-existent yet booming market? To answer this question let’s see how the two main ways to charge an EV, charging station and swapping station, fare in the future mobility scenario.   

Customer experience   Today’s market is very dynamic with customer being the actual king. The product or service needs to appeal to the customer and clearly display the benefits over the previous commodity. If the proposal lacks answer to why the product will really benefit the customer, the efforts are most likely to reap unfavorable outcomes.    

To explain this further, a canvas is given below that attempts to compare refueling, charging and swapping on the lines of factors most crucial to consumer experience. The horizontal axis captures the range of factors and vertical axis captures intensity of focus of the factor.   

Refueling time   

An ideal trip to the petrol bunk takes around 2-3 minutes today. With electric vehicles coming in, this time has changed. A swapping station without human intervention takes about 2-5 minutes while a plug-in charging facility with a type 1 & 2 takes 2-6 hours and type 3 takes 10 minutes - 2 hours.   

The charging requirements vary with vehicle landscape. A taxi aggregator or a fleet owner operating at high capacity clearly values swapping over charging but for a 2 wheeler rider or a personal car owner, its opposite. This is because for a majority of passengers on road (74%), intra-city or last mile travel is the requirement that is limited to 5-40 km/day. Visualizing the bigger picture, both the facilities seem essential but the scope really depends on how the buyer perceives it.  

Ease of use   

The range anxiety, as many call it, is very subjective. At a petrol bunk, fuel is bought keeping in mind requirements of the trip and spending capacity. Intra-city passengers are given the freedom to choose what they require. Charging stations will function on similar lines. Moreover charging points at homes, offices, cafes, malls etc will create an additional sense of ease of use for the consumers, eliminating the need to visit a charging station.    

In case of a swapping station, the flexibility of choice is not widely explored. Moreover, it becomes inefficient for operators to tailor make the battery charging levels, due to infrastructural barriers. For the inter-city travel, swapping finds a great fit into the plot, cutting down travel time to appreciable grade. But the ease of use is still a bargain. 

Freedom of design  

To swap a battery from a vehicle, the design must allow certain considerations in the structure that ensures easy deportation and reattachment of the battery pack with the body. This feature in your car will eventually limit freedom to design the vehicle and customize it to an undeniable limit. As time progresses, aesthetics and construction will gain a bigger share of consumer requirements and with the slight limitation of ideation, compromises are imminent.  

Standardization intricacy   

To access the swapping station, one needs to have a standardized battery pack i.e. the battery used in the vehicle must have similar architecture. Not only does this setup seem impossible when comparing CV with PV, 3W & 2W, it is very difficult for two rivals in the CV space to have similar designs which evidently cut down their competitive advantage and innovation capabilities.   

Companies like Tesla and Better Place have tried a good hand at comprehending swapping infrastructure, but the efforts have been frivolous due to the low adaptability from the consumer segment. Moreover, if the framework was essential to adopt, the main dilemma that vehicle manufacturers would face would be to keep a similar battery dimension for all their models. Charging on the other hand also requires standardization but to an extent of adapters that connect charging plug to the vehicle. This apparently looks workable.  

Cost of infrastructure   

The swapping station operators must ensure the number of batteries to recharge and which battery to accept. The operators find it extremely arduous to plan the answers to these two questions. Firstly, car owners with different battery degradation levels visit the operator for a swap. It is very difficult to interpret the real time condition of the battery on the basis of which the new battery will be swapped. Secondly, if the switch takes place between different or competing operators, establishing an intermediate system to retain a battery becomes a challenge which increases costs to disproportionate levels.   

If this cost was to be included in the subscription model of the driver, the vindication of the cost seems painful because of the lack of real time monitoring of condition of batteries received and batteries given for every vehicle. Also the surety of the exact same car visiting the station every time is hard to find.   

Cost of ownership   

In the charging scenario, you own your car’s battery. But in a swapping scheme, you can either own one or not own one. If you own a battery then you need to have atleast two batteries, one for powering the vehicle and one which will get charged at the swapping station, cutting down the benefits of a swapping station making your EV more expensive.  

If you let the swapping operator own your battery, it makes your EV cost somewhere closer to the petrol variant. But the price a customer pays for the energy will include the maintenance costs of the battery. Again, the cost of degradation of battery is unknown and eventually the subscription costs will include cost of two batteries with swapping costs, making the entire need to own an EV a gimmick. This can be avoided in the case of charging points which lets you pay for the electricity your battery uses.   

Finally, energy distribution infrastructure will boom as time advances and both battery charging & swapping will be given their due preference. Standardization and fast charging will become mainstream. The charging conundrum will then shift from adoption to optimization and synchronization of the already built. However, as expressed, customer needs to find real value in the proposal. It’s not only about changing times but also about changing expectations.
