After an EV battery leaves the car, who is responsible for it?

A battery replacement leaves two objects: the new pack in the car and the old one that must go somewhere. A quotation that covers only the first has left an ownership question unanswered.

For Nepal's growing EV fleet, collection and treatment need to be clear before large numbers of packs reach retirement. “Recyclable” describes a technical possibility. It does not show that a particular battery was collected, transported safely and processed by an accountable facility.

There is a local document worth reading

Paramount Motors' Nepal website links a battery recycling process document. Its scanned agreement extract identifies Paramount Motors Private Limited and Lohum Cleantech Private Limited, with an execution date of July 23, 2023 in New Delhi. It also presents a process-flow diagram.

That is concrete evidence of a published relationship and proposed process. The short document does not by itself establish current collected volumes, every contractual obligation or the destination of an individual owner's pack. Ask the distributor what collection service is operating now and which records accompany it.

The distinction matters. An agreement is more informative than a general promise to protect the environment, but it is not a public audit of completed recycling. Readers should not be asked to infer the latter from the former.

Repair, reuse and recycling are separate outcomes

A repair returns a battery or component to an approved use. A second-life project uses a battery in another application, such as stationary storage, after suitable assessment and redesign. Recycling treats materials to recover useful fractions and manage the remaining waste.

A pack that no longer suits a car may retain energy capacity. That does not automatically make it suitable for a house. Condition, fault history, cell balance, enclosure safety, controls and the new application all need professional assessment. A damaged pack is not a cheap home-backup project for an owner to wire up.

Likewise, a battery sold as “second life” has not necessarily been recycled. It remains a battery with a later disposal requirement. Traceability should continue rather than ending when it changes owners.

The Basel Convention's 2022 guidance on inventories of waste lithium-containing batteries provides a framework for identifying and accounting for these waste streams. It is international inventory guidance, not a statement that a specific Nepal shipment meets every legal requirement.

Chemistry affects the material business

Battery chemistries contain different valuable materials. A process-flow chart mentioning nickel or cobalt should not be taken to mean every pack contains the same quantities or has the same recycling economics. LFP packs, for example, differ from nickel-containing chemistries in the cathode materials involved.

A responsible offer identifies what it accepts, how condition affects handling and what treatment is planned. An owner's task is to use the authorised collection process, not to dismantle the pack to discover its chemistry.

Avoid a blanket claim that every battery is “100% recycled”. Different material fractions, losses and definitions can produce very different recovery claims. Ask for the measure: collection rate, material recovery, reuse or something else. A percentage without that definition is difficult to evaluate.

Ask who keeps the replaced pack

Before approving replacement, ask whether the old pack remains your property, is returned under warranty, attracts a core return credit or passes to the repairer under the contract. The answer should be written on the estimate or repair record.

Obtain a handover record describing the vehicle, removed assembly, receiving organisation, date and intended route. Where permitted and available, pack identification helps trace the item. Keep that record with the replacement invoice.

Ask whether collection, storage and transport are included in the price. If treatment involves another country, the responsible businesses need to handle the applicable classification, approvals and documentation. An ordinary freight offer is not evidence that cross-border battery waste movement is lawful or safe.

The Punch EV manual hosted by Sipradi directs high-voltage battery disposal through authorised service. That is model guidance worth following; it should not be expanded into an invented nationwide recycling mandate or a guaranteed buyback price.

Damage changes handling

Tell the service provider about flooding, impact, unusual heat or other known damage. A pack with those conditions may require different recovery and storage arrangements. Do not leave it at an ordinary scrap shop, open it or transport it yourself as if it were luggage.

If there is smoke, fire or an immediate hazard, keep people away and contact emergency services and the responsible recovery team. A future recycling plan does not solve the immediate incident.

What useful public reporting would show

Distributors could publish how owners request collection, what chemistries are accepted, who handles the packs and how treatment is documented. Annual quantities collected, reused and recycled would answer different questions and should be reported separately.

Nepal also benefits from inventories that distinguish lead-acid batteries from lithium-based traction packs. Historical figures about Safa Tempo batteries should retain their year and chemistry; they are not a current estimate of retired electric-car packs.

Buyers can begin with a short request at the showroom: provide the end-of-life contact and explain who takes responsibility when the pack is removed. Keep the response with the warranty documents, and request a dated handover record if a pack is later removed. The service centre should be able to identify who received it.
